This document provides an overview of computer programming and applications. It defines key terms like data, programs, and information. It explains that a computer accepts user input (data), processes it under programs to produce output (information). Programming is defined as writing instructions for a computer to operate. Popular programming languages and applications are discussed. The document outlines the learning objectives, recommended books, and grading policy for a course on computer programming and applications. It provides an example of a simple "Hello World" program in C++ with explanations of the main components - header file, main function, and output function.

1. Computer Programming & Applications

2. Course Title
Understand the terms

3. Computer
“A computer is an electronic device that accepts user input
(data) and processes it under the influence of a set of
instructions referred to as programs to produce the desired
output generally referred to as information.”
“A computer is a device process data through a program to
produce information”

4. Important Terms
Data are the raw facts may not make much meaning to the user.
Programs are set of instructions that instruct a computer what to do.
Information is result after data has been processed.
Program
Data Information

5. Programming
“Programming is the act of writing the set of instructions to operate the computer.”
Those who engage in programming as their job are known as programmers.
The language programmers use in instructing the computer is known as Programming
Language.
C, C++, Java, Python, C# and many other
Although there are many programming languages but the constructs are same.

6. Applications
“The term Application refers to Software which is a set of instructions or
code written in a program for executing a task or an operation in a
Computer. ”
• There are so many examples around you like
• MS Word
• Billing Software at Marts
• Skype etc.

7. Course Learning Objective

8. Course Learning Objective
1. Analyze a given program for all possible errors and rewrite the
corrected code.
2. Apply the concepts of programming to solve real world problems.
3. Analyze the program for possible output.

11. Writing First Program
Iram Abdullah

12. Structure of the Program
#include<iostream>
int main()
{
std::cout<<“Hello World”;
return 0;
}
This program will print the Hello World on the screen.
Header File
Main Function
Output Function

13. Header File
• include preprocessor directive causes the compiler to replace that line
with the entire text of the contents of the named source file
• iostream is a header file for C++. iostream stands for input and output
stream used to take input with the help of cin function and display output
using cout functions.
• The use of angle brackets < > informs the compiler to search the compilers
include directory for the specified file.
• Sometimes < > are replaced by " ". The use of the double quotes " "
around the filename inform the compiler to search in the current directory
for the specified file.
#include<iostream>

14. Output Function
std::cout<<“Hello World”;
• cout means "the standard character output device“
• << means "output the object“
• “Hello World” is a string or text to be displayed
• ; end the statement or line.
• std is standard namespace for C++.
• A namespace is an abstract container or environment created to hold a logical
grouping of unique identifiers or symbols (i.e. names). An identifier defined in
a namespace is associated only with that namespace.

15. Main Function
• main() is a collective name given to a set of statements.
• main( ) is a function. Every function has a pair of parentheses ( ) associated
with it.
• All statements that belong to main() are enclosed within a pair of braces {}
• Every program can have only one main() function.
• Every program starts with the main function.

16. Multiple Output Statements
#include<iostream>
int main()
{
std::cout<<“Hello World”;
std::cout<<“Computer Program”;
std::cout<<“Bye”;
return 0;
}
This program will print the Hello WorldComputerProgramBye on the screen.

17. Define Global Namespace
#include<iostream>
using namespace std;
int main()
{
cout<<“Hello World”;
cout<<“Computer Program”;
cout<<“Bye”;
return 0;
}
