Explain the structure of a code in c++.

Answer

#include<iostream>

int main()

{

std::cout<<"Hellon";

return 0;

}

An ideal structure of the code:

1. #: Preprocessor directive (used to include files)
2. <iostream>: Header file for taking input and printing output.
3. main(): code execution begins from here
4. std: standard (instead of writing std again and again we import namspace std before main function )
5. cout: Used to display output in quotation
6. n: add a line break
7. ; : marks the end of the statement.
8. return 0: exit status of a function
9. {}: Curly braces indicate the start and end of the function
