#include <iostream>
using namespace std;
int main() {
    int number = 55;
    while(number>15) {
        cout << "enter number: ";
        cin >> number;
    }

    int i = 0;
    char xs[number];
    while(i<number) {
        xs[i] = 'x';
        i++;
    }

    int f = 0;
    i = 0;
    while(i<number) {
        while(f<number) {
            cout << xs[f];
            f++;
        }

        cout << "\n";
        i++;
        f = 0;
