2. 猜数字游戏实现

参考代码：

#include <stdio.h>
#include <stdlib.h>
#include <time.h>
void game()
{
int r = rand()%100+1;
int guess= 0;
while(1)
{
    printf("请猜数字>:");
    scanf("%d", &guess);
    if(guess < r)
    {
    printf("猜⼩了\n");
    }
        else if(guess > r)
        {
        printf("猜⼤了\n");
        }
            else
            {
            printf("恭喜你，猜对了\n");
            break;
            }
        }
    }
    void menu()
    {
        printf("***********************\n");
        printf("****** 1. play ******\n");
        printf("****** 0. exit ******\n");
        printf("***********************\n");
    }
    int main()
    {
        int input = 0;
        srand((unsigned int)time(NULL));
    do
    {
    menu();
        printf("请选择:>");
        scanf("%d", &input);
    switch(input)
    {
        case 1:
        game();
        break;
        case 0:
        printf("游戏结束\n");
        break;
        default:
        printf("选择错误，重新选择\n");
        break;
    }
    }while(input);
return 0;
}

还可以加上猜数字的次数限制，如果5次猜不出来，就算失败.

#include <stdio.h>
#include <stdlib.h>
#include <time.h>
void game()
{
int r = rand() % 100 + 1;
int guess = 0;
int count = 5;
while (count)
{
    printf("\n你还有%d次机会\n", count);
    printf("请猜数字>:");
    scanf("%d", &guess);
    if (guess < r)
    {
        printf("猜⼩了\n");
    }
        else if (guess > r)
    {
        printf("猜⼤了\n");
    }
    else
    {
        printf("恭喜你，猜对了\n");
        break;
        }
        count--;
        }
        if (count == 0)
        {
        printf("你失败了，正确值是:%d\n", r);
        }
    }
    void menu()
    {
        printf("***********************\n");
        printf("****** 1. play ******\n");
        printf("****** 0. exit ******\n");
        printf("***********************\n");
    }
    int main()
    {
        int input = 0;
        srand((unsigned int)time(NULL));
        do
    {
    menu();
        printf("请选择:>");
        scanf("%d", &input);
        switch (input)
    {
    case 1:
        game();
        break;
    case 0:
        printf("游戏结束\n");
        break;
    default:
        printf("选择错误，重新选择\n");
        break;
    }
    } while (input);
return 0;
}
