how to play wav files according to inputs given?

Hello hi,
My program is like this,
PLEASE ENTER DESTINATION NUMBER:
( THEN USER INPUTS A SERIES OF NUMBERS LIKE 238947864)

How do i play wav files of dtmf tones corresponding to the numbers given?
i have used if else, but it doesnt work. Only if one number is entered it plays the corresponding dtmf wav file and exits.

But if i were to enter a series of number like 2873649, the program exits without playing at all.

thanks.

Well you could post your code, then we could actually tell you all (or at least some) of the things you did wrong.
