What's wrong with my program? I'm not finding my mistake...

Question

#include <iostream>
using namespace std;

int menu()
{

int num;
do
{
cout << "Enter a number\n";
cin >>num;
cout << "your number is: "<<num<< endl;
}
while (num != 50);

return 0;

}

Answer 1

It doesn't have a main() function

Answer 2

oh right!! I wrote "menu" instead of "main". Might have been the autocorrect.
thanks!
