Convert binary format string to int, in C

Question

How do I convert a binary string like \"010011101\" to an int, and how do I convert an int, like 5, to a string \"101\" in C?

I guess it really depends on some questions about your strings/program. If, for example, you knew your number wouldn't be bigger than 255 (IE you were only using 8 bits or 8 0s/1s), you could create a function where you hand it 8 bits from your string, traverse it and add to a sum that you returned everytime you hit a 1. IE if you hit the bit for 2^7 add 128 and the next bit you hit was 2^4 add 16.

This is my quick and dirty idea. I think more and Google for ya while at school. :D
