#include<iostream>
using namespace std;

int main(){
    int num,result=0;
    while(num % 10 == 0) {
        num= num / 10;
    }
    if(num<0){
        num=-num;
        cout<<'-';
    }
    while(num!=0){
        result=result*10+num%10;
        num/=10;
    }
    cout<<result;
   return 0; 
}

你读入 num 了吗

@Zzz123456789101112 求关注இ௰இ

#include<bits/stdc++.h>
using namespace std;
int n , s = 0;
int main() {
    cin >> n;
    while( n )
    {
        s=s * 10 + n % 10;
        n /= 10;
    }
    cout << s;
    return 0;
}
