This video is about C++ introduction and installation in Urdu. In this Urdu Tutorials Series I teach you how to program in C++ programming language.

In computer programming, A keyword is a word that is reserved by C++ for a specific use.

Comments are strings that are ignored by the compiler.
Their main purpose is to make notes in a program.
With comments , you can write a clear English (or some other natural language) explanation of the code.
Everything on the same line that follows the '//' is part of the single line comment.
Everything between a '/*...*/' pair is part of the multi-line comment.

White Space
Blank lines and spaces are called white space.
The important fact about white space is that the compiler ignores it.
Use whitespace to format your code in a more readable way.
Note that spaces inside a string(e.g., "H E L L O") are not ignored

Preprocessor Directives
In the programs we write, we will need to use some code that we did not write ourselves.
These Codes(Library, object files and header files) are made a part of our program by the preprocessor include directive.
Lines that begin with # are processed by the preprocessor before the program is compiled.

The main() Function
Every C++ program must have a main function. it is the entry point for every C++ program; that is, every C++ program starts executing at main.

A statement represents a complete instruction to a computer. To understand your source code, a compiler needs to know when one statement ends and another begins.
Every C++ statement must end with a semicolon(;) (also known as the statement terminator).
