【C语言】猜数字游戏的简单实现

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

	void game()
	{
		int ret = 0;
		int guess = 0;
		//拿时间戳来设置随机数的生成起点
		//time_t time(time_t *timer)  -时间戳的使用方法time函数(需引用time.h头文件)--time_t是它的类型，实质是long(长整型)--time_t *是指针类型
		ret = rand() % 100 + 1;
		//printf("%d\n", ret);

		while (1)
		{
			printf("请输入一个整数(1-100):\n");
			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 int)time(NULL));
		do
		{
			menu();
			printf("请选择：\n");
			scanf("%d", &input);
			switch (input)
			{
			case 1:
				game();
				break;
			case 0:
				printf("退出游戏\n");
				break;
			default:
				printf("选择错误\n");
				break;
			}
	
		} while (input);
		return 0;
