使用 Windows 和 MinGW 用 Eclipse 编写的 C++ 程序无法将输出显示到控制台视图

I installed eclipse version 3.6.2, cdt, and MinGW. I have a C++ console program in Eclipse as follows:

#include <iostream>
#include <cstdio>
using namespace std;

int main() {
    setbuf(stdout, NULL);

    for (int i = 0; i < 10000000; i++) {
        cout << "!!!Hello World!!!" << endl; // prints !!!Hello World!!!
    }
    int val;
    cin >> val;

    return 0;
}

如果我运行这个控制台程序，它应该在 Eclipse 的控制台视图中显示 Hello world，但没有任何显示.
