这就是我今天编写的内容

#include <iostream>
using namespace std;

int function1()
{
  cout<<"hello from function1()"; return 0;
}

int function2()
{
  cout<<"hello from function2()"; return 0;
}

int main()
{
    int func_diffresult = 0;
    func_diffresult = function1() - function2();
    cout<<func_diffresult; /** prints 0 correctly **/
}

输出是得到的hello from function2()hello from function1().我认为输出应该是hello from function1()hello from function2().我的编译器和我一起玩吗？
