#include<bits/stdc++.h> using namespace std; int main(){ int x; cin>>x; cout<<x<<" "<<10*x; }

刚做出一道特别难（对于我来说）的题，来一道简单的题放松一下。

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

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

GCC

#include <stdio.h>
int n;
int main(){
    scanf("%d", &n);
    printf("%d %d\n", n, n * 10);
}

#include<bits/stdc++.h>

using namespace std;

int main(){

int x;
cin>>x;
cout<<x<<" "<<x*10;
return 0;

}

#include

#include

#include

using namespace std;

int main()

{

int x;
cin>>x;
cout<<x<<" "<<x*10;
return 0;

}

1. #include<bits/stdc++.h>
using namespace std;
#define LL long long
const int N = 1e5 + 10;
const int INF = 0x3f3f3f3f;
int x;
int main()
{
    cin >> x;
    cout << x << " " << x * 10;
	return 0;
}
