输入n，用数组存各位，输出！ 简简单单 #include <bits/stdc++.h> using namespace std; int main(){ int a[3],n;cin >> n; a[0] = n % 10; a[1] = n % 100 / 10; a[2] = n / 100; cout << a[0] << a[1] << a[2]; }

#include<bits/stdc++.h> using namespace std; int main(){ int n,a,b,c; cin>>n>>a>>b>>c; a=n%10; b=n/10%10; c=n/100; cout<<a<<b<<c; }

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

直接上吧，很好理解，用 string 存一下，在倒序输出即可。
