1. using a switch statement for each case of 0,1,2,3,4,5,6,7,8,9, then 
the break?

2. using isnum ? (isalnum then isalpha)
Could be done using #define to define macro isnum as 
(if(isalnum(variable_name) && if(!(isalpha(variable_name)))
assuming that you are searching for numbers, as opposed to digits, in 
which case you have isdigit, and you could probably use
while(isdigit(variablename)) to retrieve numbers
?

? here is not the conditional operator :)
