NetBeans BUILD FAILED (exit value 2, total time: 1s)

Question

我下载了 NetBeans 并尝试运行一个基本程序，但弹出了这个错误，我不知道这是什么意思，也不知道为什么我不能运行该程序，如果它有帮助的话，这是我的代码：

#include <stdio.h>
int main() {
    
    int x = 3, y = 3;
    printf("X=%d, Y=%d\n", x, y);
    printf("Input new values for both variables:\n");
    printf("X:");
    scanf("%d", &x);
    printf("Y:");
    scanf("%d", &y);
    printf("X=%d, Y=%d\n", x, y);

    return 0;
}

这是这个东西：
