因此，我正在我的编程 I 课程中编写一个程序，我们被分配创建一个程序，该程序将检查银行的​​路由号码是否有效。每次我在 NetBeans 上运行这个程序时，我都没有问题。但是，当我通过我们的 Ubuntu 学生服务器运行它时，我得到了这个疯狂的错误。我一直在尝试调试这个程序一段时间，但不太清楚这个错误是从哪里来的。我已经尝试更改数组大小，但没有运气，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

这是我的源代码的副本：

using namespace std;

int main() {

    string code;

    int routing[9];

    int subtotals = 0;
    int products[8];
    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 << endl;

    for (int i = 0; i < 8; i++) { //print multipliers
        cout << multipliers[i] << " ";
    } cout << endl;

    for (int i = 0; i < 8; i++) { // print and calculate products
        products[i] = routing[i] * multipliers[i];
        cout << products[i] << " ";
    } cout << endl;

    for (int i = 0; i < 8; i++) { // calculate subtotals and print
        subtotals += products[i];

    } cout << endl;

    cout << subtotals << endl; // print sum
    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;
}

如果您有任何人熟悉此错误消息，请帮助！太感谢了！

您尝试使用 gcc 选项 -fsanitize-address 进行构建，它会在您超出堆栈写入时崩溃。
