In this video, we will learn the basic structure / parts of C++ Program.
A program in C++ consists of the following parts:
• Preprocessor directive
• Main() function
• Program body (C++ statements)
Preprocessor Directives
Preprocessor directives are instructions given to the preprocessor. A program called the preprocessor reads the source code. The preprocessor searches for special lines that begin with the # symbol. These lines contain commands, or directives, that cause the preprocessor to amend or process the source code in some way. The preprocessor directives start with hash symbol #. These directives are written at the start of program. Include preprocessor directive is used to include header files in the program
main( ) Function
The main() function is the starting point of a C++ program. The control enters main() function and starts executing its statements when the program is run. Each program must contain main() function. Any number of statements can be written in the body of the main() function.
The statements of the program are written in curly braces. The curly brace { is called opening brace and } is called closing brace.These statements are collectively known as the body of a program. Each statement in C++ language is terminated by semicolon (;). It is called statement terminator.
Step by step explanation.
Easy to follow and understand.

excellent sir. i have a question. can we use return 1; or any other integer instead of zero. If yes then why we always use 0?

@icscomputer 4 жыл бұрын

In Main function we must return 0 because, here returning 0 means a success message or in other words it stats there was no error in program execution. If we return 1 it will be considered an error "No line selected" and if we return a value greater than 1 indicates just an error. So in Main function, we must return 0 if we have used int before Main function.
