The document contains information about Tarandeep Kaur, including her name, section, and roll number. It then lists and describes various topics related to functions in C++, including definition of functions, function calling, function prototypes, void functions, local vs global variables, function overloading, and recursion. Examples are provided to illustrate function calling, passing arguments, return values, and differences between call by value and call by reference.
Functions allow programmers to structure C++ programs into modular segments of code to perform individual tasks. There are two types of functions: library functions and user-defined functions. User-defined functions are defined using a return type, function name, and parameters. Functions can be called by value or by reference and can also be inline, recursive, or friend functions.
This document discusses functions in C++. It defines what a function is and explains that functions are the building blocks of C++ programs. Functions allow code to be reused, making programs easier to code, modify and maintain. The document covers function definitions, declarations, calls, parameters, return types, scope, and overloading. It also discusses local and global variables as well as pass by value and pass by reference.
Constructors are special class functions which performs initialization of every object. The Compiler calls the Constructor whenever an object is created. Destructor on the other hand is used to destroy the class object.
C++ functions require prototypes that specify the return type and parameters. Function overloading allows multiple functions to have the same name but different signatures. Default arguments allow functions to be called without providing trailing arguments. Inline functions expand the function body at the call site for small functions to reduce overhead compared to regular function calls.

The document discusses functions in C programming. The key points are:
1. A function is a block of code that performs a specific task. Functions allow code reusability and modularity.
2. main() is the starting point of a C program where execution begins. User-defined functions are called from main() or other functions.
3. Functions can take arguments and return values. There are different ways functions can be defined based on these criteria.
4. Variables used within a function have local scope while global variables can be accessed from anywhere. Pointers allow passing arguments by reference.
Call by value or call by reference in C++Sachin Yadav
Call by value means passing the value directly to a function. The called function uses the value in a local variable; any changes to it DO NOT affect the source variable. In call by value method, the called function creates its own copies of original values sent to it. Any changes, that are made, occur on the function’s copy of values and are not reflected back to the calling function.
This document discusses polymorphism in C++. It defines static polymorphism as function overloading and overriding, where functions can have the same name but different parameters. Dynamic polymorphism uses virtual functions and runtime binding via pointers. Virtual functions allow overriding in derived classes. Pure virtual functions make a class abstract, requiring implementation in derived classes. Interface classes are like abstract classes but inheritance is not required.

The document discusses functions in C programming. It defines a function as a self-contained block of code that performs a specific task. Functions make code more modular and reusable. There are two types of functions: standard/library functions and user-defined functions. Functions can take input parameters and return values. Functions are an essential part of program structure in C as they help organize code and logic.
Function is a set of statement which is designed to perform some specific task. Function gives functionality to programmer to use one module(task) for more times rather then write same code again and again....
Functions allow code to be reused by defining formulas that can be called from different parts of a program. Functions take in inputs, perform operations, and return outputs. They are defined outside of the main body with a function prototype, and can be called multiple times from within main or other functions. This document demonstrates how to define a FindMax function that takes in two numbers, compares them, and returns the maximum number. It shows function prototypes, defining the function outside of main, and calling the function from within main to find the maximum of two user-input numbers.
The document discusses C++ functions. It explains that functions allow code to be reused by grouping common operations into reusable blocks of code called functions. Functions have three parts: a prototype that declares the function, a definition that implements it, and calls that execute the function. Functions can take parameters as input and return a value. Grouping common code into well-named functions makes a program more organized and maintainable.
The document discusses functions in C programming. It defines what functions are and their advantages, such as modularity, reusability and avoiding code repetition. It covers different types of functions based on arguments and return values. Additionally, it discusses function definitions, prototypes, scope, storage classes, recursion, call by value vs reference and examples of functions.
This document discusses classes and objects in C++. It defines a class as a user-defined data type that implements an abstract object by combining data members and member functions. Data members are called data fields and member functions are called methods. An abstract data type separates logical properties from implementation details and supports data abstraction, encapsulation, and hiding. Common examples of abstract data types include Boolean, integer, array, stack, queue, and tree structures. The document goes on to describe class definitions, access specifiers, static members, and how to define and access class members and methods.
This document discusses parameters in C++. There are two types of parameters: formal parameters defined in a function and actual parameters passed during a function call. C++ supports two ways of passing parameters: call by value where the formal parameter is a copy of the actual value, and call by reference where the formal parameter is an alias to the actual parameter. Call by reference allows a function to modify the original value. While it is more efficient for large data types, it can be ambiguous whether a parameter is intended for input or output.
The document discusses arrays of objects and pointers to objects in C++. It defines an array of objects as a collection of objects of the same type. Syntax for an array of objects is Class_name object_name[size]. It also defines a pointer to an object as a variable that stores the address of an object. A pointer can be used to access members of a class using dot (.) or arrow (->) operators. The document provides examples of an array of objects, a pointer to an object, and an array of object pointers in C++.
Pointers,virtual functions and polymorphism cpprajshreemuthiah
This document discusses key concepts in object-oriented programming in C++ including polymorphism, pointers, pointers to objects and derived classes, virtual functions, and pure virtual functions. Polymorphism allows one name to have multiple forms through function and operator overloading as well as virtual functions. Pointers store the memory address of a variable rather than the data. Pointers can be used with objects, arrays, strings, and functions. Virtual functions allow calling a derived class version of a function through a base class pointer. Pure virtual functions define an abstract base class that cannot be instantiated.
This document discusses if and if-else statements in C++. It provides the syntax for if statements, which execute code if a test expression is true. If the expression is false, the code is skipped. It also covers if-else statements, which allow specifying different code blocks to execute depending on whether the test expression is true or false. Examples are given of programs using if and if-else statements to check if a user-input integer is positive or negative.

This document discusses different types of functions in C programming. It defines standard library functions as built-in functions to handle tasks like I/O and math operations. User-defined functions are functions created by programmers. Functions can be defined to take arguments and return values. Functions allow dividing programs into modular and reusable pieces of code. Recursion is when a function calls itself within its own definition.
This document discusses pointers in C++. It defines pointers as variables that store memory addresses of other variables. It covers declaring and initializing pointers, using the address and dereference operators, pointer arithmetic, references, and passing pointers as function arguments. The document includes examples of pointer code and output to demonstrate these concepts.
This document discusses classes, objects, and methods in Java. It defines a class as a user-defined data type that contains fields and methods. Objects are instances of classes that allocate memory at runtime. Methods define behaviors for objects and are declared within classes. The document covers defining classes, creating objects, accessing members, constructors, method overloading and overriding, static members, passing objects as parameters, recursion, and visibility control.
Function overloading in C++ allows defining multiple functions with the same name as long as they have different parameters. This enables functions to perform different tasks based on the types of arguments passed. An example demonstrates defining multiple area() functions, one taking a radius and the other taking length and breadth. Inline functions in C++ avoid function call overhead by expanding the function code at the call site instead of jumping to another location. Demonstrated with an inline mul() and div() example.

1. Functions allow breaking code into reusable chunks that perform specific tasks. The main() function is required in every C program.
2. Functions are declared with a return type, name, and parameters. Definitions include the function body.
3. Standard library functions like strcat() and memcpy() are pre-defined for common tasks.
4. Functions are called by name and pass arguments by value or reference. Parameters allow customizing a function's behavior.
5. Recursion allows a function to call itself, enabling solutions to problems like factorials and Fibonacci sequences.
The document provides an overview of functions in C++. It discusses declaring functions with prototypes specifying the return type and parameters. It also covers defining functions by providing the body enclosed in curly braces. Functions are called by specifying the name and passing arguments for any parameters. Parameters can be passed by value, where a copy is made, or by reference, where changes to the parameter also affect the argument. The document uses examples to demonstrate declaring, defining, calling, and passing arguments to functions. It also discusses default parameter values and recursion.
Functions allow programmers to organize C++ code into reusable blocks to perform tasks, where a function is defined with a name and parameters and can be called from other parts of the program. Functions may take parameters, return values, and be called recursively or by reference to modify external variables. The C++ standard library provides header files and built-in functions to help programmers write functions and programs.
This document discusses defining and calling functions in C++. It explains that a function is defined with a return type, name, and parameters. Functions can be called by passing arguments matching the parameters. Default values can be set for parameters, allowing a function to be called with fewer arguments than parameters defined.
Functions allow programmers to organize and reuse code. There are two types of functions: library functions provided by C++ and user-defined functions created by the programmer. Functions communicate by passing arguments and returning values. Key concepts for functions include declaration, definition, call, pass by value, pass by reference, and pointers. Virtual functions allow for runtime polymorphism by calling the correct overridden function based on the object's type.
Functions allow programmers to organize C++ code into reusable blocks of statements. There are two types of functions: library functions provided in header files and user-defined functions created by the programmer.

The document discusses C++ functions. It defines what functions are and their uses in breaking down problems into smaller tasks. There are two types of functions: standard functions that are part of the C++ language and user-defined functions. A function has a signature defining its return type and parameters. Functions are declared and defined in two steps - declaration and implementation. Data can be shared between functions through parameters, which come in two varieties: value parameters that copy argument values, and reference parameters that can modify the original argument values.
The document discusses functions in C++. It defines a function as a block of code that performs a specific task. There are two types of functions: built-in functions provided by the language and user-defined functions created by the programmer.

It also covers topics like function overloading, function prototypes, recursion, and global versus local variables.
Lecture#7 Call by value and reference in c++NUST Stuff
This document discusses references and reference parameters in C++. It explains that call by reference allows a function to directly access and modify the original argument, unlike call by value where only a copy is passed. A reference parameter creates an alias for the argument, allowing changes to affect the original. The document provides examples demonstrating pass by value versus pass by reference using reference parameters, and also covers default arguments, reference initialization requirements, and function overloading.
The document discusses functions in C programming. It defines functions as self-contained blocks of code that perform a specific task. Functions make a program more modular and easier to debug by dividing a large program into smaller, simpler tasks. Functions can take arguments as input and return values. Functions are called from within a program to execute their code.
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.
This talk will cover ScyllaDB Architecture from the cluster-level view and zoom in on data distribution and internal node architecture. In the process, we will learn the secret sauce used to get ScyllaDB's high availability and superior performance. We will also touch on the upcoming changes to ScyllaDB architecture, moving to strongly consistent metadata and tablets.
2. Definition of functions
Function calling
Function definition
Void function
Remarks on function
Local v/s Global variables
Function call methods
Concept of recursion
Function overloading
3. A function is a subprogram that acts on data
and often returns a value.
4. Functions invoked by a function–call-statement which
consist of it’s name and information it needs (arguments)
Boss To Worker Analogy
A Boss (the calling/caller function) asks a worker (the
called function) to perform a task and return result when
it is done.
Boss
Main
Worker
Worker Worker
Function Z
Function A Function B
Worker Worker
Note: usual main( ) Calls other
Function B1 Function B2 functions, but other functions
can call each other
5. • Functions called by writing
functionName (argument);
or
functionName(argument1, argument2, …);
• Example
cout << sqrt( 900.0 );
• sqrt (square root) function
• The preceding statement would print 30
• All functions in math library return a double
Function Arguments can be:
- Constant sqrt(9);
- Variable sqrt(x);
- Expression sqrt( x*9 + y) ;
sqrt( sqrt(x) ) ;
6. • Calling/invoking a function
– sqrt(x);
– Parentheses an operator used to call function
• Pass argument x
• Function gets its own copy of arguments
– After finished, passes back result
Function Name argument Output
3
cout<< sqrt(9);
Parentheses used to enclose argument(s)
7. Functions
◦ Modularize a program
◦ Software reusability
Call function multiple times
Local variables
◦ Known only in the function in which they are defined
◦ All variables declared in function definitions are local variables
Parameters
◦ Local variables passed to function when called
◦ Provide outside information
8. Function prototype
◦ Tells compiler argument type and return type of function
◦ int square( int );
Function takes an int and returns an int
◦ Explained in more detail later
Calling/invoking a function
◦ square(x);
◦ Parentheses an operator used to call function
Pass argument x
Function gets its own copy of arguments
◦ After finished, passes back result
9. Example function
int square( int y )
{
return y * y;
}
return keyword
◦ Returns data, and control goes to function’s
caller
If no data to return, use return;
◦ Function ends when reaches right brace
Control goes to caller
Functions cannot be defined inside other
functions
10. // Creating and using a programmer-defined function.
#include <iostream.h>
Function prototype: specifies
int square( int ); // function prototype data types of arguments and
return values. square
int main()
expects an int, and returns
{
// loop 10 times and calculate and output
an int.
// square of x each time
for ( int x = 1; x <= 10; x++ )
cout << square( x ) << " "; // function call
cout << endl;
Parentheses () cause function to be called.
When done, it returns the result.
return 0; // indicates successful termination
} // end main
// square function definition returns square of an integer
int square( int y ) // y is a copy of argument to function
{
return y * y; // returns square of y as an int
Definition of square. y is a
copy of the argument passed.
} // end function square Returns y * y, or y squared.
1 4 9 16 25 36 49 64 81 100
11. // Finding the maximum of three floating-point (real) numbers.
#include <iostream.h>
double maximum( double, double, double ); // function prototype
int main()
{
double number1, number2;
double number3; Function maximum takes 3
arguments (all double) and
cout << "Enter three real numbers: "; returns a double.
cin >> number1 >> number2 >> number3;
// number1, number2 and number3 are arguments to the maximum function call
cout << "Maximum is: "
<< maximum( number1, number2, number3 ) << endl;
return 0; // indicates successful termination
} // end main
// function maximum definition. x, y and z are parameters
double maximum( double x, double y, double z )
{
double max = x; // assume x is largest Enter three real numbers: 99.32 37.3 27.1928
if ( y > max ) // if y is larger, Maximum is: 99.32
max = y; // assign y to max
Enter three real numbers: 1.1 3.333 2.22
if ( z > max ) // if z is larger,
Maximum is: 3.333
max = z; // assign z to max
return max; // max is largest value
} // end function maximum
12. Function prototype contains
◦ Function name
◦ Parameters (number and data type)
◦ Return type (void if returns nothing)
◦ Only needed if function definition after function call
Prototype must match function definition
◦ Function prototype
double maximum( double, double, double );
◦ Definition
double maximum( double x, double y, double z
)
{
…
}
13. If the Function does not RETURN result, it is called void
Function
#include<iostream.h>
void add2Nums(int,int);
main()
{ int a, b;
cout<<“enter tow Number:”;
cin >>a >> b;
add2Nums(a, b)
return 0;
}
void add2Nums(int x, int y)
{
cout<< x<< “+” << y << “=“ << x+y;
}
14. If the function Does Not Take Arguments specify this with EMPTY-LIST OR
write void inside
#include<iostream.h>
void funA();
void funB(void)
main()
{ Will be the same
funA(); in all cases
funB();
return 0;
}
void funA()
{
cout << “Function-A takes no arqumentsn”;
}
void funB()
{
cout << “Also Function-B takes No argumentsn”;
}
15. Local variables
◦ Known only in the function in which they are defined
◦ All variables declared inside a function are local variables
Parameters
◦ Local variables passed to function when called (passing-
parameters)
Variables defined outside and before function main:
◦ Called global variables
◦ Can be accessible and used anywhere in the entire
program
16. #include<iostream.h>
int x,y; //Global Variables
int add2(int, int); //prototype
main()
{ int s;
x = 11;
y = 22;
cout << “global x=” << x << endl;
cout << “Global y=” << y << endl;
s = add2(x, y);
cout << x << “+” << y << “=“ << s;
cout<<endl;
cout<<“n---end of output---n”;
return 0;
} global x=11
int add2(int x1,int y1) global y=22
{ int x; //local variables Local x=44
x=44;
11+22=33
cout << “nLocal x=” << x << endl;
return x1+y1; ---end of output---
}
17. Call by value
• A copy of the value is passed
Call by reference
• The caller passes the address of the value
Call by value
Up to this point all the calls we have seen are call-by-value, a copy
of the value (known) is passed from the caller-function to the called-
function
Any change to the copy does not affect the original value in the
caller function
Advantages, prevents side effect, resulting in reliable software
18. Call By Reference
We introduce reference-parameter, to perform call by reference. The caller
gives the called function the ability to directly access the caller’s value, and to
modify it.
A reference parameter is an alias for it’s corresponding argument, it is stated in
c++ by “flow the parameter’s type” in the function prototype by an
ampersand(&) also in the function definition-header.
Advantage: performance issue
void function_name (type &);// prototype
main()
{
-----
------
}
void function_name(type ¶meter_name)
19. #include<iostream.h>
int squareVal(int); //prototype call by value function
void squareRef(int &); // prototype call by –reference function
int main()
{ int x=2; z=4;
cout<< “x=“ << x << “before calling squareVal”;
cout << “n” << squareVal(x) << “n”; // call by value
cout<< “x=“ << x << “After returning”
cout<< “z=“ << z << “before calling squareRef”;
squareRef(z); // call by reference
cout<< “z=“ << z<< “After returning squareRef”
return 0;
}
x=2 before calling squareVal
int squareVal(int a)
4
{
x=2 after returning
return a*=a; // caller’s argument not modified
z=4 before calling squareRef
}
z=16 after returning squareRef
void squarRef(int &cRef)
{
cRef *= cRef; // caller’s argument modified
}
20. Main calls another function…..normal
A function calls another function2….normal
A function calls itself ?! Possible?? YES
A recursive function is one that call itself.
21. A recursive function is called to solve a problem
The function knows to solve only the simplest cases
or so-called base-cases
Thus if the function called with a base-case, it simply
returns a result. But if it is called with more complex
problem, the function divides the problem into two
conceptual pieces, one knows how to do, and another
doesn't know what to do.
The second case/piece must resemble the original
problem, but be a slightly simpler/smaller version of
the original problem
22. Function overloading
◦ Functions with same name and different parameters
◦ Should perform similar tasks
I.e., function to square ints and function to square floats
int square( int x) {return x * x;}
float square(float x) { return x * x; }
A call-time c++ complier selects the proper function by
examining the number, type and order of the parameters
