注意数组越界。
#include<iostream>
#include<cmath>
using namespace std;

char letter[10001];
void Output(int cap,int type) {
    int w = 0, l = 0;
    for (int i = 0; i < cap; i++) {
        if (letter[i] == ‘W‘)
            w++;
        if (letter[i] == ‘L‘)
            l++;
        if (((w == type||l==type)&&(abs(l-w)>=2))||((w>type||l>type)&&(abs(l-w)==2)) ){
            cout << w << ‘:‘ << l;
            w = 0, l = 0;
            cout << endl;
        }
    }
    cout << w << ‘:‘ << l;
}

    int i = 0;
    while ((letter[i] = getchar()) != EOF) {

            break;
        i++;
    }
    Output(i, 11);
    cout << endl<<endl;
    Output(i, 21);

    return 0;
