avoid a lot of if-else checks

Question

I am working on a moderately large C file where I need to do processing for 3 different exclusive conditions. (if condition 1 is present do this, if 2 is present do something else and likewise). So, at many places in that file, I need to do if/else checks - which looks dirty. I have some 50 places where I am doing these checks.

Is there a better way, to make code look cleaner?

Answer 1

If the conditions are really exclusive then I'd start with three separate functions, one for each process. Break any common code out into their own functions that you can call from the three process functions. The only conditional left should be where you decide which of the three process functions to call.
