简单的剪刀石头布小游戏函数实现

• 开发环境：vs2019
• 包含头文件：#include<time.h>
• 控制台型英文界面
• 说明：
• 0—石头
• 1—剪刀
• 2—布

void thereGame()
{
	while (1)
	{
		cout << "    StoneScissorsCloth\n-Two wins form three games-\n";
		cout << "----------" << endl;
		cout << "  0.Stone\n  1.Scissors\n  2.cloth\n" << endl;
		cout << "----------" << endl;

		int UseNum;
		int frequency = 0;
		//种下随机数种子
		//srand函数用来设置rand函数
		srand((unsigned int)time(NULL));
		int PcNum = rand() % 3;// PcNum范围：rand() % n  --- [0 , n - 1]
		cout << "Please select a number at 0-2:" << endl;
		scanf_s("%d", &UseNum);
		while (UseNum < 0 || UseNum>2)
		{
			cout << "Error!Please re-enter." << endl;
			cout << "Please select a number at 0-2:" << endl;
			scanf_s("%d", &UseNum);
		}
		getchar();//清空缓存区
		switch (UseNum)
		{
		case 0:
			cout << "UseNum is stone." << endl;
			break;
		case 1:
			cout << "UseNum is Scissors." << endl;
			break;
		case 2:
			cout << "UseNum is cloth." << endl;
			break;
		}

		switch (PcNum)
		{
		case 0:
			cout << "Pc is stone." << endl;
			break;
		case 1:
			cout << "Pc is Scissors." << endl;
			break;
		case 2:
			cout << "Pc is cloth." << endl;
			break;
		}

		int winOrFailure = UseNum - PcNum;

		switch (winOrFailure)
		{
		case 0:
			cout << "Equal." << endl;
			break;
		case -1:
		case 2:
			cout << "you win." << endl;
			break;
		case -2:
		case 1:
			cout << "you failure" << endl;
			break;
		}

		cout << "Are you continue?(enter n eixt)." << endl;
		cout << "Press any key to continue." << endl;
		char ch = 0;
		while ((ch = getchar()) != '\n')
		{
			if (ch == 'n' || ch == 'N')
				return;
		}
		system("cls");//系统清屏函数, 在 .c文件中可能无法使用
	}
