Answer 3

In C and C++ programs the main function is of type int and therefore it should return an integer value. The return value of the main function is considered the "Exit Status" of the application. On most operating systems returning 0 is a success status like saying "The program worked fine".

Answer 4

yeah it's optional too use but I preferd to use return value because every function if it is not void return some value

Answer 5

#include<iostream>
int main(){
int k;
std::cin>>k; //for console input
std::cout<<k; //for console output
return 0;
}
