@66kkCED 试试这个？

n=strlen(compress);
for(int i=0,cnt=0,op='0';i<=n;i++)
{
    if(compress[i] ==op)    cnt++;
    else
    {
        op=compress[i];
        cout << cnt << " ";
        cnt=1;
    }
}

@DreamLand_zcb

奇怪，还是不太行

没弄清楚这题是有什么输入输出限制么？

@66kkCED 你把输入再改一下试试？

    char last[40000], now[200];
    cin >> now;
    n=strlen(now);
    strcat(last,now);
    for(int i=2;i<=n;i++)
    {
        cin >> now;
        strcat(last,now);
    }
    cout << n << " ";

@66kkCED 这是我的代码

n=strlen(last);
    for(int i=0,sum=0,num='0';i<=n;i++)
    {
        if(last[i] == num)
            sum++;
        else
        {
            num=last[i];
            cout << sum << " ";
            sum=1;
        }
    }

@DreamLand_zcb

嗯，AC了，感谢大佬！

ps.看来这个题输入单字符读入会出错，得使用字符串读入了
