Question

Write a program to keep track of a match consisting of a series of games between two people: player A and player B, and report the outcome. The input consists of a sequence of letters A or B. If the input is A, it indicates that A has won a game. If it is B, then it indicates B has won a game. The first player to win 5 or more games with a difference of 2 or more games between him and his opponent wins the match. If no player wins the match in 20 games then the match is declared a tie after these 20 games have been played

Answer 1

#include <iostream>
using namespace std;


int main(){


    char match;
    int i,a,b;
    a=0;
    b=0;
    for(i=1;i<=20;++i){
cout<<"Enter a if a has won or b if b has won"<<endl;
    cin>>match;
    if(match=='a'){
    ++a;
    }
    if(match=='b'){
    
    ++b;
    }


    if(a-b>=2  && a>=5){
    
cout<<"a won"<<" a="<<a<<" "<<"b="<<b<<endl;
break;
    }


    if(b-a>=2  && b>=5){
    
cout<<"b won b="<<b<<" a="<<a<<endl;
break;
    }


    if((a-b<2)  && (i==20)|| (b-a<2 ) && (i==20)) {
    
cout<<"draw "<<" a="<<a<<" "<<"b="<<b<<endl;
break;
    }
    }
    return 0;
