Answer 2

in c
this is a warning
main()
{

}
In c++
this is error
main()
{

}

Answer 3

With C++ and C, the main function must be declared as an int, and therefore must return an int. In your code, you had changed the main function to a void, returning an error. Try changing void main() to int main() and add a line at the end of your function that returns 0.

int main(){
statement(s)
return 0;
}

Answer 4

main requiring a return type of int couldn't possibly be the answer could it?

Answer 5

It's necessary for main() function to return an integral value (0) to operating system because it checks the number to verify that the program has run successfully or not . If it returns a value 0 it has ran successfully or any other value means it contains a problem

int main()
{
//
}
