Question

我的教授给了我一个写一个16场比赛尼姆游戏的协议。

任务的一部分是让PC也能做出动作。因此，我试图通过使用SRAND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，当他拿下零重量时，PC也会占据空中并且撞到墙上。

所以，那就是我已经做过的事情。有什么想法吗？

#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("\n\n\t  ************ \n");
        printf("\t *THE NIM GAME* \n");
        printf("\t  ************ \n\n");

        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: %d\n", i+1, sticks[i]);
            printf("\n");

            if(theChecker == 1)
            {
                printf("Choose a row: ");
                scanf("%d", &choiceRow);
                printf("Choose a sick: ");
                scanf("%d", &choiceStick);
                while((choiceRow <= 0) || (choiceRow > 4) || (sticks[choiceRow - 1] < choiceStick) || (choiceStick == 0))
                {
                    printf("\n\t    !!!ERROR!!!\n\tInvalid row or stick\n\nCheck stick log above\n\n");
                    printf("Choose a row: ");
                    scanf("%d", &choiceRow);
                    printf("Choose a sick: ");
                    scanf("%d", &choiceStick);
                }
                sticks[choiceRow-1] -= choiceStick;
                stickSum -= choiceStick;
            }
            else    //pc move starts-------------------------------------------
            {
                while(((pcRow <= 0) || (pcRow > 4)) && sticks[choiceRow - 1] == 0)
                {
                    time_t seconds;
                    seconds = 0;
                    time(&seconds);
                    srand((unsigned int)seconds);
                    pcRow = rand() % 4;
                }
                printf("PC ROW: %d\n", pcRow);

                while((sticks[pcRow - 1] < pcStick) || (pcStick == 0))
                {
                    time_t seconds2;
                    seconds2 = 0;
                    time(&seconds2);
                    srand((unsigned int)seconds2);
                    pcStick = rand() % 16;
                }
                printf("PC STICK: %d\n\n", pcStick);


                sticks[pcRow-1] -= pcStick;
                stickSum -= pcStick;
            }

            if((theChecker == 1) && (stickSum == 0))
                printf("\n\n!!!GAME OVER!!! You took the last stick!!!\n\n");
            else if((theChecker == 2) && (stickSum == 0))
                printf("\n\n!!!CONGRATS!!! You won!!!\n\n");
            theChecker++;
            if(theChecker == 3)
                theChecker -= 2;
        }

        printf("\nPress r to restart the game or any key to end the game: ");
        scanf("%c", &answer);
        printf("\n");
    }
    while(answer == 'r');
    return 0;`enter code here`
}

Answer 1

不要多次调用srand()，它用于初始化随机种子，您始终将其初始化为相同的值，即内部状态一遍又一遍地重置，总是产生相同的伪随机值。

我说你总是传递相同的种子，因为time()具有秒分辨率，并且在一秒钟内，整个游戏都被播放和终止。

您只需在程序开头调用srand()，以防止程序在程序运行期间选择相同的值，而不是在同一运行中。
