使用不起作用的字符串打印出std :: array

Question

我有以下代码，但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cout << arrayRef[i] << endl;行，我得到错误，有一个unhandeld异常，但问题是什么？为什么抛出异常，我该如何纠正？

异常追踪：

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

交换线条：

    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;

并且您会在stoi来电时看到错误，您正在使用一些损坏的字符串调用stoi。
