又是一道简单的题，直接照题意编就是了

#include<iostream>
using namespace std;

const int MAX = 250;
int main()
{
    char buffer[MAX],text[MAX];
    int p,t;
    while(cin.getline(buffer,MAX))
    {
        for(p=t=0;p<250 && buffer[p]!='\0';p++,t++)
        {
            if(buffer[p]=='@')
            {
                t=0;
                text[t]='\0';
                t--;
            }
            else if(buffer[p]=='#')
            {
                t-=2;
                if(t<0) t=-1;
                text[t+1]='\0';
            }
            else
            {
                text[t]=buffer[p];
                text[t+1]='\0';
            }
        }
        cout<<text<<endl;
    }
    return 0;
}
