这道题用点小心思会做得没意义，还是自己练练的好

#include<iostream>
#include<algorithm>
using namespace std;
int arr[2];
int main() {
    cin >> arr[0] >> arr[1] >> arr[2];
    sort(arr, arr + 3);
    cout << arr[0] << " " << arr[1] << " " << arr[2];
}

#include<iostream> #include<algorithm> using namespace std;

int main(){ int a[3]; for(int i=0;i<3;i++){ cin>>a[i]; } sort(a,a+3); for(int i=0;i<3;i++){ cout<<a[i]<<" "; } }
