i have seen this link before, thank you for replying for my query. This might sound weird to you( i am just a beginer). what i am trying to do is:
There 3 files say add, prime and odd, now i want all of them should be in 1 file in such a way that, the inputs from user shud just be like add 10 or prime 10 or something and they shud get the output. Donno whether to use getopts or not a friend just hinted, that's y asked about them.
