Seeking knowledge is an obligation upon every Muslim” (Sunan Ibn Majjah, 224)

Let’s start with the first set of slides 1 Basics OF Programming Let’s start with the first set of slides

Text Book Object Oriented Programming in c++ any updated Edition by Robert Lafore

Computer Science computer science is the study of automating algorithmic processes that can measure.

First Program #include "stdafx.h" #include<iostream> using namespace std; int main() { cout <<"Hello World"; getchar(); }

Namespace The line using namespace std; tells the compiler to use the std namespace. Namespaces are a relatively recent addition to C++. a namespace is a container for a set of identifiers (also known as symbols, names) Namespaces provide a level of direction to specific identifiers, thus making it possible to distinguish between identifiers with the same exact name.

main() • The next line // main() is where program execution begins. is a single- line comment available in C++. • Single-line comments begin with // and stop at the end of the line

int main() The line int main() is the main function where program execution begins.

cout The next line cout << "This is my first C++ program."; causes the message "This is my first C++ program" to be displayed on the screen.

return 0; The next line return 0; terminates main()function and causes it to return the value 0 to the calling process.

Whitespace in C++: • A line containing only whitespace, possibly with a comment, is known as a blank line, and C++ compiler totally ignores it. • int age;

Comments • /* This is a comment */ • /* C++ comments can also • * span multiple lines • */

Data Types • While doing programming in any programming language, you need to use various variables to store various information. • Variables are nothing but reserved memory locations to store values. This means that when you create a variable you reserve some space in memory
