C语言的小游戏:猜数字游戏和关机小程序

关机小程序:

int main()
{
	char input[20] = { 0 };
	system("shutdown -s -t 60");
	while (1) {
		printf("你的电脑即将关机,如果你输入“我是猪”则取消关机\n");
		scanf("%s", &input);
		if (strcmp(input, "我是猪") == 0) {
			system("shutdown -a");
			break;
		}
	}
	return 0;
}

 猜数字游戏:主要难点在于使用时间戳来生成随机数

#define _CRT_SECURE_NO_WARNINGS

#include 
#include 
#include 
#include 
#include 
#include 
void game() {
	//生成1-100的随机数
	int ret = rand()%100+1;
	int guess = 0;
	while (1) {
		scanf("%d", &guess);
		if (guess < ret) {
			printf("猜小了\n");
		}
		else if (guess > ret) {
			printf("猜大了\n");
		}
		else {
			printf("恭喜你猜对了\n");
			break;
		}
	}
}
void menu() {
	printf("****************\n");
	printf("*1:start 0:exit*\n");
	printf("****************\n");
}
int main()
{
//根据时间戳来生成随机数
	srand((unsigned int)time(NULL));
	int put = 0;
	do {
		menu();
		scanf("%d", &put);
		switch (put) {
		case 1:
			printf("请输入你猜的数\n");
			game();
			break;
		case 0:
			break;
		default:
			printf("输入错误");
		}
	} while (put);
	return 0;
}
