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。
