XXXXXXX
XXXXXXXXX

Answer 1

const int n = 5;
for (int i = 0; i < n; i++)
{
for (int j = 0; j < 2*i + 1; j++)
cout << "X";
cout << endl;
}

2) Solution for normal pyramide
const int n = 5;
for (int i = 0; i < n; i++)
{
for (int j = 0; j < n-i-1; j++)
cout << " ";
for (int j = 0; j < 2 * i + 1; j++)
cout << "X";
cout << endl;
}
