C++—有限次数猜数字

C++ 学习循环结构小案例

#include
using namespace std;
#include

//随机猜数字1~100
int main()
{
	//添加随机数种子：利用当前系统时间生成随机数，防止每次随机数都一样
	srand((unsigned int)time(NULL));
	int num = rand() % 100 + 1;
	int val = 0;
	int i = 0;
	int b = 5;
	cout << "猜数字游戏\t" << endl;
	cout << "请输入一个1~100的数字" << endl;
	while (1) 
	{
		cin >> val;
		if (val > num)
		{
			cout << "您猜大了" << endl;
			i++;
		}
		else if (val < num)
		{
			cout << "您猜小了" << endl;
			i++;
		}
		else
		{
			cout << "恭喜您猜对了" << endl;
			break;
		}
		
		if(i>=b) //如果猜错次数超过设定数字，则挑战失败，游戏结束
		{
			cout << "您已猜错  "<
