Calling functions from main() in c++

what are some guidlines to changing int main to call other functions in your code I was told not to use int main2(), int main3() and so on also how do I declare them so that the compiler calls them and recognizes them would it be

#include <iostream>
int main()
int main 2()
using namespace std;

int main()
  code here ..... 1st function
int main2()
  code here .... 2nd function

or would it be

#include <iostream>
int anothername()
int seconddifferentname()
using namespace std;

int anothername()
  code here ..... 1st function
int seconddifferentname()
  code here .... 2nd function

Answer 1

You create new functions and call them from main:

void foo() {}
void goo() {}

int main()
{
  foo();
  goo();
}

There’s nothing technically wrong with having main1 or main2 methods, but there’s only one entry point of a valid C++ program, and that’s main.
