stack - *** 检测到堆栈粉碎 *** : a. 终止

Question

因此，我正在编程 I 课上编写一个程序，我们被分配创建一个程序来检查银行的​​路由号码是否有效。每次我在 NetBeans 上运行该程序时，都没有出现任何问题。 但是，当我通过 Ubuntu 学生服务器运行它时，我收到了这个疯狂的错误。我已经尝试调试这个程序一段时间了，但不太明白这个错误是从哪里来的。我尝试过更改数组大小，但没有成功，我仍然收到此错误。这是错误的副本:

Enter a bank routing number: 
103000648
1 0 3 0 0 0 6 4 8 
7 3 9 7 3 9 7 3 
7 0 27 0 0 0 42 12 
7 7 34 34 34 34 76 88 
88
8
the check code is valid

这是我的源代码的副本:

    int sum = 0;

    cout << "Enter a bank routing number: " << endl;
    cin >> code;

    char ch_code[8];
    strcpy(ch_code, code.c_str()); //store character code into array

    for (int i = 0; i < 9; i++) { //convert string to integer and print routing
        routing[i] = ch_code[i] - '0';
        cout << routing[i] << " ";

    cout << subtotals % 10 << endl; // check digit

    if(subtotals % 10 == routing[8]) {
        cout << "the check code is valid" << endl;
    }

    else cout << "the check code is invalid" << endl;
}

如果您熟悉此错误消息，请帮忙!非常感谢!
