题目说“当一局比赛结束后，下一局立刻开始”，以及“如果一局比赛刚开始，则此时比分为0:0”，说明0:0的情况要输出。

因此，不要特判0:0，直接输出剩余的比分就行了，另外你的代码中只输入“E”也不用特判了。

修改如下：

#include<bits/stdc++.h>
using namespace std;

string s;
char c;
int a11,b11;
int a21,b21;

int main(){
    while(true){
        cin>>c;
        if(c == 'E') break;
        s += c;
    }
    int n = s.length();
    for(int i = 0;i < n;i++){
        if(s[i] == 'W') a11++;
        else b11++;
        if(abs(a11 - b11) >= 2 && max(a11,b11) >= 11){
            cout<<a11<<":"<<b11<<endl;
            a11 = 0;
            b11 = 0;
        }
    }
    cout<<a11<<":"<<b11<<endl;
    cout<<endl;
    for(int i = 0;i < n;i++){
        if(s[i] == 'W') a21++;
        else b21++;
        if(abs(a21 - b21) >= 2 && max(a21,b21) >= 21){
            cout<<a21<<":"<<b21<<endl;
            a21 = 0;
            b21 = 0;
        }
    }
    cout<<a21<<":"<<b21<<endl;
}
