Printing a variable value in a custom font

Question

I'm making a game in SDL and I made my own custom font, now if I for example want to print the score variable I don't want to have to check what the variables value is like this:

if ( Score == 0 )
    font.show_text( 0, 0, "Score: 0", screen );
if ( Score == 1 )
    font.show_text( 0, 0, "Score: 1", screen );

("font" is a class and "show_text" is a member that prints the text to the screen)
Is there a way to display the value maybe with the string class or anything else?

Don't mix up: variable, its value and presentation of a string.
You don't "print a variable", you and don't "print" anything!

Even if "font.show_text" API existed I would not use such API as it's a wrong abstraction.

Your answer depends on the UI library you use (always use tags: WPF, WinForm, or what?).
When you say "SDL", you should explain what of the possible meanings do you imply, see for disambiguation: http://en.wikipedia.org/wiki/SDL[^] :-).

Typically, you use Control of FrameworkElement (WPF only) to present a string in the UI. They all have the property Font. As simple as that.
