用c语言写石头剪刀布小游戏

可以使用如下的代码实现石头剪刀布小游戏：

#include<stdio.h>
#include<stdlib.h>
#include<time.h>

int main()
{
    int player_choice, computer_choice;
    int player_score = 0, computer_score = 0;
    const char *options[3] = {"Rock", "Paper", "Scissors"};

    srand(time(NULL)); // Seed the RNG

    printf("Welcome to the Rock, Paper, Scissors Game!\n");

    while(1) {
        printf("Enter your choice (0 for Rock, 1 for Paper, 2 for Scissors): ");
        scanf("%d", &player_choice);

        if(player_choice < 0 || player_choice > 2) {
            printf("Invalid choice. Try again.\n\n");
            continue;
        }

        computer_choice = rand() % 3;
        printf("You chose %s. Computer chose %s.\n", options[player_choice], options[computer_choice]);

        // Determine winner
        if(player_choice == computer_choice) {
            printf("Tie! No one wins.\n\n");
        }
        else if(player_choice == 0 && computer_choice == 2 || 
                player_choice == 1 && computer_choice == 0 || 
                player_choice == 2 && computer_choice == 1) {
            printf("You win!\n\n");
            player_score++;
        }
        else {
            printf("Computer wins.\n\n");
            computer_score++;
        }

        printf("Score: You %d - %d Computer\n\n", player_score, computer_score);
    }

    return 0;
}

这份代码实现了一个基本的石头剪刀布游戏，具体来说：

- 使用rand()函数生成一个0到2之间的随机数，表示电脑出的选项；
- 根据玩家选择和电脑选择的不同，判断当前轮的胜负关系，并更新分数；
- 不断循环，直到玩家选择退出游戏。
