Question

这是我的作业说明：

您将编写一个可以进行乐透的程序。

乐透由1至70的5个数字和1至70的强力球组成   数字1-30。

前5个数字不应重复（中奖数字相同）。   强力球可以重复前5个数字中的任何一个。

您将购买10,000张乐透彩票。每张票有6张   数字（5个数字和1个战俘）。

给每张彩票随机数字，并与中奖数字进行比较   （获奖号码仅生成一次）。

匹配5个数字和强力球号码，您将赢得大奖！

仅匹配5个数字，您将赢得$ 1,000,000。

仅匹配4个数字，您将赢得50,000美元。

仅匹配3个数字，您将赢得7美元。

匹配3个以下的数字，但是您获得了强力球并赢得$ 4。

其他任何东西都不会赢。

这是我的代码：

#include<iostream>
#include<time.h>
using namespace std;
int main()
{
    srand(time(0));
    int nums[6];
    int powerball;
    nums[5] = powerball;
    int win5p;
    int win5;
    int win4;
    int win3;
    int winu3p;

    for (int x = 0; x <= 10; x++)
    {
        cout << "The generated numbers are:" << endl;
        for (int x = 0; x <= 5; x++)
        {
            nums[x] = rand() % 71 + 1;
            cout << nums[x] << endl;
        }
        for (int x = 0; x < 1; x++)
        {
            cout << "The generated powerball is:" << endl;
            powerball = rand() % 31 + 1;
            cout << powerball << endl;
        }
    }

    int compnums[6];
    int comppowerball;
    compnums[5] = comppowerball;

    for (int x = 0; x <= 10; x++)
    {
        cout << "The winning numbers are:" << endl;
        for (int x = 0; x <= 5; x++)
        {
            compnums[x] = rand() % 71 + 1;
            cout << compnums[x] << endl;
        }

        cout << "The winning powerball is:" << endl;
        for (int x = 0; x < 1; x++)
        {
            comppowerball = rand() % 31 + 1;
            cout << comppowerball << endl;
        }

        for (int x = 0; x <= 5; x++)
        {
            if ((nums[0] == compnums[x]) && (nums[1] == compnums[x]) && (nums[2] == compnums[x]) && (nums[3] == compnums[x]) && (nums[4] == compnums[x]) && (nums[5] == compnums[x]) && (powerball == comppowerball))
            {
            win5p = true;
            }
            if ((nums[0] == compnums[x]) && (nums[1] == compnums[x]) && (nums[2] == compnums[x]) && (nums[3] == compnums[x]) && (nums[4] == compnums[x]) && (nums[5] == compnums[x]))
            {
            win5 = true;
            }
            // I get lost right here. I don't even know if I'm doing any of this correctly.
        }
    }

是的。如果有人可以帮助我，我将是有史以来最幸福的女孩。我有10张票而不是10,000张票，因此调试时更容易浏览，但完成时必须为10,000张。匹配的乐透号码可以在任何地方，因此，如果number [1]与compnumbers [4]相匹配，则仍将被视为匹配。请问任何您需要问的问题，我知道这很麻烦。
