Python:

n=int(input('nhap n: '))
a=[int(input('nhap a[%d]: '%i)) for i in range (1,n+1)]
sc=[a[i] for i in range (n) if (a[i]%2==0)]
print('so luong so chan:',len(sc))
print('so luong so le:',n-len(sc))

Java:

import java.util.Scanner;
import java.util.ArrayList;
public class Main{
    public static void main(String[] args){
        Scanner stdin = new Scanner(System.in);
        System.out.print("nhap n: ");
        int n = stdin.nextInt();
        ArrayList<Integer> a = new ArrayList<>();
        int dem=0;
        for (int i=0; i<n; i++){
            System.out.printf("nhap a[%d]: ",i+1);
            a.add(stdin.nextInt());
            if (a.get(i)%2==0) dem++;
        }
        System.out.printf("so luong so chan: %d\n",dem);
        System.out.printf("so luong so le: %d",n-dem);
        stdin.close();
    }
}

C++:

#include <iostream>
using namespace std;
int main(){
    long n;
    cout << "nhap n: ";
    cin >> n;
    long a[n],dem=0;
    for (long i=0; i<n; i++){
        cout << "nhap a[" << i+1 << "]: ";
        cin >> a[i];
        if (a[i]%2==0) dem++;
    }
    cout << "so luong so chan: " << dem << endl;
    cout << "so luong so le: " << n-dem << endl;
}
