篮球赛对阵

概述篮球赛对阵

下面是内存溢出 jb51.cc 通过网络收集整理的代码片段。

内存溢出小编现在分享给大家，也给大家做个参考。

模拟篮球赛对阵的情况

// 篮球对阵.cpp : 定义控制台应用程序的入口点。// 本程序采用赛制为：共有9个班参赛，每轮通过抽签，两两对决，单场淘汰制，在进入决赛之前每一轮都会有一只轮空球队。// 本程序每组对决时采用固定胜率，此胜率为程序作者初步估计各班水平给出的胜率，不能完全反映真实情况。// 对决时根据胜率，选择随机数的方式确定胜负与否，每组对决取10次随机数，根据随机数所在的区域确定最终胜负关系，// 对于随机数所在区域的解释：例如A班对B班获胜几率为60%，则取1-100中的随机数字，数字在1-60内则A班胜，数字在61-100内则B班胜。// 如在两边获胜的区域各取到了5次，则程序再重新抽取10次随机数，直至这10次中两边区域取到的数字不相同为止。// 本程序将会对整个的比赛流程模拟10次，程序将会在模拟期间输出每次抽签的结果以及最终的胜负关系，在10次模拟结束后，系统将会给出夺冠次数最多的球队，和我班（4班）在每轮被淘汰的次数。// 本模拟程序仅供个人练习使用，并不代表真实的赛制和比赛结果，不成为可靠参考数据。#include "stdafx.h"#include "iostream"#include "ctime"#include
