C++ :

#include <iostream>
using namespace std;
int main() {
    int n;
    cin >> n;
    int arr[100];
    for (int i = 0; i < n; ++i) {
        cin >> arr[i];
        if (arr[i] % 2 != 0) {
            arr[i] = 0;
        }
    }
    for (int i = 0; i < n; ++i) {
        cout << arr[i] << " ";
    }
    return 0;
}
