一层循环就行

#include <bits/stdc++.h>

using namespace std ;

int a[11] ;

int main ( ) {

    int n ;
    cin >> n ;

    a[1] = 1 ;
    for ( int i = 2 ; i <= n ; i ++ ) a[i] = a[i - 1] * i ;

    int x = 0 , y = 0 ;
    for ( int i = 1 ; i <= n ; i += 2 ) x += a[i] ;
    for ( int i = 0 ; i <= n ; i += 2 ) y += a[i] ;

    cout << x << ' ' << y ;

    return 0 ;

}
