Answer 1

#include <iostream>
using namespace std;
int main()
{
    int a, b;
    char c;
    cin>>a>>b>>c;
    for (int i = 0; i < b; i++)
    {
        int ans = i;
        while(ans > 0)
        {
            cout<<" ";
            ans--;
        }
        for (int j = 0; j < a; j++)
        {
            cout<<c;
        }
        cout<<endl;
    }
    return 0;
}
