found 'int (' at global scope (was a declaration intended?)
#include <iostream>
using namespace std;

#include <windows.h>

void my_interface()
{
system("cls");

HANDLE hOutput;
COORD loc;
loc.X = 0; loc.Y=2;
hOutput = GetStdHandle(STD_OUTPUT_HANDLE);
SetConsoleCursorPosition(hOutput, loc);
}

int min(int x, int y)
{
return ((x < y) ? x : y);
}

void main()
{
my_interface();
cout << "hello world" << endl;
}
问题补充：如何能够避免出现这种问题呢？？

[解决办法]
你去掉他 应该也是可以用的。

min是已经被系统定义的。

#define min(a, b) (((a) < (b)) ? (a) : (b))
