C++ 程序在执行时停止响应

Question

关于我的电脑的基本信息:Windows 7 x64 操作系统
8GB 内存
使用 MingW 编译器

因此，每次我在编译后通过终端运行我的程序时，它都会立即停止响应。我自己似乎找不到问题，所以我要求多一双眼睛为我指出。我目前几乎是 C++ 的初学者，所以请多多包涵。

    #include <iostream>
    #include <cstdlib>
    #include <string>
    #include <vector>
    #include <ctime>

    using namespace std;

int main()
{   
    bool correct = false;
    srand(time(NULL));  
    vector<string> guess;
    vector<string> pallete;
    vector<string> secret;
    pallete.push_back("red");
    pallete.push_back("green");
    pallete.push_back("blue");
    pallete.push_back("yellow");
    for(int i = 0; i < 4 ; i++)
    {
        secret.push_back(pallete.at(rand()%secret.size()));
    }
    for(int j = 0; j < 4 ; j++)
    {
        guess.push_back(pallete.at(rand()%guess.size()));
    }
    vector<string> secretMem = secret;
    cout << "the guess was:";
    for(int x = 0; x<4; x++)
    {
        cout << guess[x] << endl;
    }

    while(correct == false)
    {
        int blackP = 0; 
        int whiteP = 0;
        secret = secretMem;
        for (int idxB = 0; idxB < secret.size(); idxB++)
        {
            if (guess[idxB] == secret[idxB])
            {
                secret[idxB] = "0";
                guess[idxB] = "1";
                blackP++;
            }
        }   
        for (int idxW = 0; idxW < secret.size(); idxW++)
            for (int idyW = 0; idyW < guess.size(); idyW++)
            {
                if (secret[idxW] == guess[idyW])
                {
                secret[idxW] = "0";
                guess[idxW] = "1";
                whiteP++;
            }
        }
        if (blackP == 4)
        {
            cout << "Congratulations you win." << endl << "The secret code was:"<< endl;
            for(int y = 0; y<4; y++)
            {
                cout << secretMem[y] << endl;
            }
            correct = true;
        }
        else
            cout << "you scored: " << blackP << " Black pegs" << "and" << whiteP << " White pegs" << endl;
    }
    return 0;
}

另外....这种可怕的代码格式是怎么回事....我无法像编写代码时那样在预览中正确排列....

除以零？ secret.size() 初始值为 0。

secret.push_back(pallete.at(rand()%secret.size()));
