Dev-Cpp 报错[Error] ld returned 1 exit status，这是因为什么？

Question

Dev-Cpp报错[Error] ld returned 1 exit status

事先说明一下，我把黑色的运行框关闭了也是一样的结果，应该是不因为有程序正在运行才返回[Error] ld returned 1 exit status的。

代码粘出，共大家帮忙检查

运行结果及报错内容

报错内容：}（没错，就是一个大括号）
具体存在于函数mmcs的最后一行：

int mmcs() {
    memset(n, 0, 250);
    int *arr2 = new int[arrlen];
    dispArr(arr2, arrlen);
    delete arr2;
    for (int i = 0; i <= 194; i++) {
        b[i] = Random();
        for (int i = 0; i <= 194; i++) {
            d[i] = 0;
            e[i] = 0;
        }
    }
    for (int i = 195; i <= 227; i++) {
        b[i] = 0;
    }

    for (int j = 0; j <= 100000; j++) {
        for (int i = 226; i >= 0; i--) {
            if (ceil(b[i] / 6) == i - 194) {
                if (n[i] == S + l) {
                    b[i] = 0;
                    n[i] = 0;
                } else {
                    n[i]++;
                }
            } else {
                if (b[i + 1] == 0) {
                    b[i + 1] = b[i];
                    b[i] = 0;
                }
            }
        }
        t++;
        for (int i = 226; i >= 0; i--) {
            if (b[i] != 0) {
                a = 1;
            }
        }
        if (a == 0) {
            break;
        }
        a = 0;
        c[j] = t * dt;
        cout<<c[j]<<endl;
    }
    t = 0;
}

关闭了所有的运行框且尝试过重新编译，没有反应。

希望各位能够帮忙解答，谢谢！

有程序正在运行才返回[Error] ld returned 1 exit status的
很多情况都是这个原因，题主可以把软件关了，加速球加速一下，等大概十几秒左右，然后再打开，运行一下试试。

希望对题主有所帮助，可以的话，帮忙点个采纳！
