This is the presentation file about inheritance in java. You can learn details about inheritance and method overriding in inheritance in java. I think it's can help your. Thank you.
Command-line arguments are given after the name of the program in command-line shell of Operating Systems.
To pass command line arguments, we typically define main() with two arguments : first argument is the number of command line arguments and second is list of command-line arguments.
A function is a group of statements that together perform a task. Every C program has at least one function, which is main(), and all the most trivial programs can define additional functions. You can divide up your code into separate functions.
Its the first phase of the compiler,useful in generating lexemes ,tokens and matching of the pattern.Its helpful in solving GATE/ UGCNET problems.For more insight refer http://tutorialfocus.net/

Presentation on polymorphism in c++.pptxvishwadeep15
This is a PPT on polymorphism which lays a solid foundation on the basic concepts, useful for 1st year COMPUTER SCIENCE STUDENTS or any students keen on learning cpp , or computer science in general
A function provides a convenient way of packaging a computational recipe, so that it can be used as often as required. A function definition consists of two parts: interface and body. The interface of a function (also called its prototype) specifies how it may be used. It consists of three entities:
The function name. This is simply a unique identifier.
The function parameters (also called its signature). This is a set of zero or more typed identifiers used for passing values to and from the function.
The function return type. This specifies the type of value the function returns. A function which returns nothing should have the return type void.
The body of a function contains the computational steps (statements) that comprise the function.

The application is develop by using best combination of front-end and back-end languages. The application is totally design like flat user interface. This flat user interface is more attractive user interface in 2017. The application is gives more important to the system functionality. The application is to manage the student’s details, driver’s details, bus details, bus route details, bus fees details and more. The application has only one unit for admin. The admin can manage the entire application. The admin can login into the application by using username and password of the admin. The application is develop for big and small colleges. It is more user friendly for non-computer person. Even they can easily learn how to manage the application within hours. The application is more secure by the admin. The system will give an effective output for the VB.Net and SQL Server given as input to the system. The compiled java program given as input to the system, after scanning the program will generate different reports. The application generates the report for users. The admin can view and download the report of the data. The application deliver the excel format reports. Because, excel formatted reports is very easy to understand the income and expense of the college bus. This application is mainly develop for windows operating system users. In 2017, 73% of people enterprises are using windows operating system. So the application will easily install for all the windows operating system users. The application-developed size is very low. The application consumes very low space in disk. Therefore, the user can allocate very minimum local disk space for this application.

Maintaining high-quality standards in the production of TMT bars is crucial for ensuring structural integrity in construction. Addressing common defects through careful monitoring, standardized processes, and advanced technology can significantly improve the quality of TMT bars. Continuous training and adherence to quality control measures will also play a pivotal role in minimizing these defects.
2. Polymorphism
The word polymorphism is derived from Greek word Poly
which means many and morphos which means forms.
Polymorphism can be defined as the ability to use the same
name for two or more related but technically different tasks.
Eg-woman plays role of daughter,sister,wife,mother etc.

3. Overloading in C++
What is overloading
– Overloading means assigning multiple
meanings to a function name or operator
symbol
– It allows multiple definitions of a function with the same
name, but different signatures.
C++ supports
– Function overloading
– Operator overloading
3 Ritika sharma
4. Why is Overloading Useful?
Function overloading allows functions that
conceptually perform the same task on
objects of different types to be given the
same name.
Operator overloading provides a convenient
notation for manipulating user-defined
objects with conventional operators.
4 Ritika sharma
5. Function Overloading
Is the process of using the same name for two or more
functions
Requires each redefinition of a function to use a different
function signature that is:
different types of parameters,
or sequence of parameters,
or number of parameters
Is used so that a programmer does not have to remember
multiple function names
5 Ritika sharma
6. Function Overloading
Two or more functions can have the same name but different
parameters
Example:
int max(int a, int b)
{
if (a>= b)
return a;
else
return b;
}
float max(float a, float b)
{
if (a>= b)
return a;
else
return b;
}
6 Ritika sharma
7. Overloading Function Call Resolution
Overloaded function call resolution is done by
compiler during compilation
– The function signature determines which definition
is used
a Function signature consists of:
– Parameter types and number of parameters
supplied to a function
a Function return type is not part of function signature
and is not used in function call resolution

8. void sum(int,int);
void sum(double,double);
void sum(char,char);
void main()
{
int a=10,b=20 ;
double c=7.52,d=8.14;
char e=‘a’ , f=‘b’ ;
sum(a,b); //calls sum(int x,int y)
sum(c,d); //calls sum (double x,double y)
sum(e,f); // calls sum(char x,char y)
}
void sum(int x,int y)
{
vout<<“n sum of integers are”<<x+y;
}
void sum(double x,double y)
{
cout<<“n sum of two floating no are”<<x+y;
}
void sum(char x,char y)
{
cout<<“n sum of characters are”<<x+y;
8 Ritika sharma
9. Output:
Sum of integers 30
sum of two floating no are 15.66
sum of characters are 195
9 Ritika sharma
11. Function Selection Involves following
Steps.
Compiler first tries to find the Exact match in which the type
of argument are the same,and uses that func.
If an exact match is not found,the compiler user the integral
promotions to the actual argument such as,char to int, float
to double.
When either of them fails ,build in conversions are
used(implicit conversion) to the actual arguments and then
uses the function whose match is unique.but if there are
multiple matches,then compiler will generate an error
message.
11 Ritika sharma
12. For ex: long square(long n)
long square(double x)
Now a func. call such as square(10) will cause an
error because int argument can be converted into
long also and double also.so it will show
ambiguity.
User defined conversion are followed if all the
conversion are failed.
12 Ritika sharma
14. Scope
The scope of a variable is the portion of a program where the
variable has meaning (where it exists).
A global variable has global (unlimited) scope.
A local variable’s scope is restricted to the function that
declares the variable.
A block variable’s scope is restricted to the block in which
the variable is declared.
14 Ritika sharma
15. Understanding Scope
Some variables can be accessed throughout an entire
program, while others can be accessed only in a limited part
of the program
The scope of a variable defines where it can be accessed in a
program
To adequately understand scope, you must be able to
distinguish between local and global variables
15 Ritika sharma
16. Local variables
Parameters and variables declared inside the definition of a
function are local.
They only exist inside the function body.
Once the function returns, the variables no longer exist!
That’s fine! We don’t need them anymore!
16 Ritika sharma
17. Block Variables
You can also declare variables that exist only within the body
of a compound statement (a block):
{
int foo;
…
…
}
17 Ritika sharma
18. Global variables
You can declare variables outside of any function definition –
these variables are global variables.
Any function can access/change global variables.
Example: flag that indicates whether debugging information
should be printed.
18 Ritika sharma
19. Distinguishing Between Local
and Global Variables
Celebrity names are global because they are known to people
everywhere and always refer to those same celebrities
Global variables are those that are known to all functions in a
program
Some named objects in your life are local
You might have a local co-worker whose name takes
precedence over, or overrides, a global one
19 Ritika sharma
20. A note about
Global vs. File scope
A variable declared outside of a function is available
everywhere, but only the functions that follow it in the file
know about it.
The book talks about file scope, I’m calling it global scope.
20 Ritika sharma
21. Block Scope
int main(void) {
int y;
{
int a = y;
cout << a << endl;
}
cout << a << endl;
}
Error – a
doesn’t exist outside
the
block!
21 Ritika sharma
Editor's Notes
Multiple function with same name and same number of parameters differ only in data types
