Answer 1

#include <iostream>
#include <stdio.h>
using namespace std;
int f(int x)
{
    x = x * 2;
    for (int i = 1; i <= x; i += 2)
    {
        int y = (x - i) / 2;
        for (int j = 1; j <= y; j++)
        {
            cout << ' ';
        }
        for (int j = 1; j <= i; j++)
        {
            cout << '*';
        }
        cout << endl;
    }
}
int main()
{
    int n;
    while (cin >> n)
    {
        f(n);
    }
    return 0;
