How to stringify an expression in C

Question

Is there a way to evaluate an expression before stringification in c?

example:

#define stringify(x)  #x
...
const char * thestring = stringify( 10 *          


        

Answer 1

You need to interpret the string. C doesn't do that by itself, look up a library that'll do it for you.

There are others, just search google.
