I'd use an array so you could use subtraction to find the letter. [code]#include <iostream> int main ( void ) { static const char alphabet[] = "abcdefghijklmnopqrstuvwxyz"; int input; while ( std::cin >> input ) { std::cout << alphabet [ (input - 1) % (sizeof alphabet - 1) ] << …

Not my strong suit here, but isn't [FONT=Courier New]f()[/FONT] inherited by both [FONT=Courier New]b[/FONT] and [FONT=Courier New]c[/FONT] since it is public in [FONT=Courier New]a[/FONT]?

I found this would remove the ambiguity.[code] w.b::f();[/code]Or.[code] …
