头一次写稍复杂一点的代码,光教学视频就看了三四遍。

#define _CRT_SECURE_NO_WARNINGS
#include<stdio.h>

void menu()
{
printf("########################\n");
printf("## 1.play 0.exit ##\n");
printf("########################\n");
}

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

void game()
{
int ret = 0;
int guess = 0;
ret = rand() % 100 + 1;
//printf("%d\n",ret);
while (1)
{
printf("请猜数字:>");
scanf("%d", &guess);
if (guess > ret)
printf("猜大了\n");
else if (guess < ret)
printf("猜小了\n");
else
{
printf("恭喜你,猜对了!!!\n");
break;
}
}
}

int main()
{
int input = 0;
srand((unsigned)time(NULL));
do
{
menu();
printf("请选择>:");
scanf("%d", &input);
switch (input)
{
case 1:
game();
break;
case 0:
printf("退出游戏\n");
break;
default:
printf("输入错误\n");
break;

}
} while (input);
return 0;
}

但是玩起来还蛮好玩的,数字范围都在1到100之间。
