Question

调试：运行时检查失败＃2-变量'LoggerThread'周围的堆栈已损坏。

我找不到解决方案:(反正可以解决这个问题。

#include <iostream>

using namespace std;

int main()
{
    string LoginMessage = "Please Login";
    string loginsuccess = "Login Correctly";
    float x = 0;
    char afpl[6][7] = {

        "A",
        "B",
        "C",
        "@",
        "*$",
        "$"
    };

    cout << LoginMessage << endl;

    float y = 10;
    cin >> x;

    int i = /* Would be random - */ 20;

    int finalx = x + y * i;
    int temp = finalx;
    int last = temp / i;
    if (last > 5) {
        last = last / 3;
    }

    cout << afpl[last] << "|" << last << "|" << finalx << endl;
    if (finalx == 210) {
        if (last == 3) {
            if (afpl[6][7] = '@') {
                cout << loginsuccess << endl;
            }
        }
    }

}

没有警告，只有ERROR，这是输出

'PythonVsCSVsC++.exe' (Win32): Loaded 'C:\Users\MYNAME\source\repos\PythonVsCSVsC++\Debug\PythonVsCSVsC++.exe'. Symbols loaded.
'PythonVsCSVsC++.exe' (Win32): Loaded 'C:\Windows\SysWOW64\ntdll.dll'.

The thread 0x188c has exited with code 0 (0x0).

我该如何解决此问题，我尝试在各处找到解决方法，但所有解决方案都无法解决我的问题。无论如何，有没有解决这个问题的方法：），顺便说一下，这是c ++。

行if (afpl[6][7] = '@')分配给afpl。我认为您的意思是if (afpl[6][7] == '@')。另外afpl[6][7]超出范围。那是未定义的行为，是什么导致堆栈损坏（写到错误的内存位置）。数组索引从0开始。
