打印出 std::array 字符串不起作用

Question

我有以下代码，它没有打印到控制台：

void generateRandomStringArray(array<string, N> &arrayRef)
{
    cout << "Generating random string array..." << endl;
    for (size_t i = 0; i < N; i++)
    {
        arrayRef[i] = randomString();
        cout << "Value of i = " << i << ": " << stoi(arrayRef[i]) << endl;
        cout << arrayRef[i] << endl;
    }

    cout << "Generating array successful." << endl;
};

问题出在第 cout << arrayRef[i] << endl; 行，我得到错误，存在未处理的异常，但问题是什么？为什么抛出异常，我该如何纠正？

异常跟踪：

First-chance exception at 0x76EFC42D in SortingAlgorithms.exe: Microsoft C++ exception: std::invalid_argument at memory location 0x0344F8EC.

If there is a handler for this exception, the program may be safely continued.

Answer 1

换行：

    cout << "Value of i = " << i << ": " << stoi(arrayRef[i]) << endl;
    cout << arrayRef[i] << endl;

到

    cout << arrayRef[i] << endl;
    cout << "Value of i = " << i << ": " << stoi(arrayRef[i]) << endl;

并且您会看到错误出现在 stoi 调用中，您在调用 stoi 时使用了一些损坏的字符串。
