猜数字游戏

核心

• 生成随机数
  • int randnum = rand() % 100 + 1;
• 随机种子(保证每次随机的数字都是新的数字)
  • srand((unsigned int)time(NULL));

具体实现

void Menu(){
	printf("*************************\n");
	printf("******1.开始游戏*********\n");
	printf("******0.退出游戏*********\n");
	printf("*************************\n");
}
void Game(){
	int randnum = rand() % 100 + 1;
	printf("请输入数字:");
	while (1){
		int num = 0;
		scanf("%d", &num);
		if (num < randnum){
			printf("猜小了\n");
		}
		else if (num > randnum){
			printf("猜大了\n");
		}
		else{
			printf("恭喜!\n");
		}
	}
}
int main () {
	srand((unsigned int)time(NULL));//随机种子
	while (1){
		Menu();
		printf("请选择:");
		int input = 0;
		scanf("%d", &input);
		switch (input){
		case 1:
			Game();
			break;
		case 0:
			printf("退出成功\n");
			break;
		default:
			printf("输入有误,请重新输入!\n");
			break;
		}
	}
	return 0;
}
