C++问题-字符串变换

Question

重复字符居然不让放

呃，永远只有80分，看不懂哪扣分了，求同学们的帮助！

#include<bits/stdc++.h>
using namespace std;
int n,i,sum=1,cf,al,ks,js;
bool flag=0;
int main(){
    char a[300]={};
    string d;
    while(cin.get(a[al])){
        if(a[al]=='\n')break;
        al++;
    }
    lable:
    for(int j=1;j<=al;j++){
        if(a[j]==a[j-1]){sum++;ks=j-1;cf=a[j]-32;}
        else if(a[j]!=a[j-1]&&sum!=1){
            //cout<<111<<endl;
            js=j-1;
            d="";
            for(int q=js+1;q<al;q++){
                d.push_back(a[q]);
            }
            d.push_back(cf);
            d+=to_string(sum);
            for(int q=0;q<ks;q++){
                d.push_back(a[q]);
            }
            al=al-sum+2;
            d.erase(al);
            //cout<<d<<endl;
            for(int q=0;q<d.size();q++){
                a[q]=d[q];
            }
            cout<<d<<endl;
            sum=1;
            flag=1;
            goto lable;
        }
    }
    if(flag==1)cout<<d;
    else cout<<a;
    return 0;   
}
