string alpha = "abcdefghijklmnopqrstuvwxyz{";
string::const_iterator x = alpha.begin();
string::const_iterator x2;

for ( int p = 1; p <= 14; p++ )
{
int w; // index variable
int count = 0; // set to 0 each iteration

// output spaces
for ( int k = 13; k >= p; k-- )
cout << ' ';

x2 = x; // set starting point

// output first half of characters
for ( int c = 1; c <= p; ++c )
{
cout << *x2;
++x2; // move forward one letter
++count; // keep count of iterations
} // end for

// output back half of characters
for ( w = 1, x2 -= 2; w < count; w++ )
{
cout << *x2;
--x2; // move backward one letter
} // end for

++x; // next letter
cout << '\n';
} // end for
} // end main
