@由比滨丶雪乃

我给你小改了一下就好了

R21841589 记录详情

#include <iostream>
#include <cstdlib>
#include <cstring>
using namespace std;
int stack[1010];
char s[1010];

int main()
{
    cin>>s;
    int i=0,top=0,x=0,y;
    while(s[i]!='@') 
    {
        switch(s[i])
        {
            case'+':stack[--top]+=stack[top+1];break;
            case'-':stack[--top]-=stack[top+1];break;
            case'*':stack[--top]*=stack[top+1];break;
            case'/':stack[--top]/=stack[top+1];break;
            case'.':stack[++top]=x;x=0;;break;
            default:x=x*10+s[i]-'0';break;
        }
        i++;
    }
    cout<<stack[top]<<endl;
    return 0;   
}

两个简单的初始化错误

不客气
