NIM游戏对PC初学者

我的教授给我布置了一个作业，让我写一个16局的尼姆游戏。

任务的一部分是使PC也采取行动。所以，我试图通过使用SRAND来解决问题，但PC选择了相同的行和相同数量的棒。更重要的是，PC也采取空行，并撞墙时，他采取零质量。

所以，这就是我已经做过的。任何想法吗?

#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#define row 4
int main()
{
    int theChecker = 1, sticks[row] = {1,3,5,7}, stickSum, i, choiceRow, choiceStick, pcRow, pcStick;
    char answer;
    do
    {
        printf("nnt  ************ n");
        printf("t *THE NIM GAME* n");
        printf("t  ************ nn");
        stickSum = sticks[0] + sticks[1] + sticks[2] + sticks[3];
        while(stickSum > 0)
        {
            printf("nStick log:n");
            for(i = 0; i < row; i++)
                printf("Row %d: %dn", i+1, sticks[i]);
            printf("n");
            if(theChecker == 1)
            {
                printf("Choose a row: ");
