Undefined reference to '_WinMain@16'?

[jwC5fSEw]

Here's my code:

#include <iostream>
using namespace std;

struct intStruct{
    int num;
};

void change(intStruct* test, int input){
    test->num = input;
}

void display(intStruct* test){
    cout << "The number is " << test->num;
}

It took me a while to get this working properly, and once I pruned all the errors out a new one popped up:

undefined reference to '_WinMain@16'

It doesn't reference a line, and I have no idea what it means. Any help here?

Do you have a main function?

[jwC5fSEw]

Huh. I didn't realize a program needed a main function to compile. Thanks for the assistance!

It needs a main function to be able to link to an executable. (You are getting a linker error, not
a compile error).

[Vidus]

you need a main() function where you use your functions.something like

int main()
{
int Number;
struct intStruct Test;

cout << "Enter a number\n"
cin >> Number;
change(Test,Number);
display(Test);
return 0;
}
