I've been told to study up on four c segments: code, data, stack, heap. I know that googleing stack and heap will probably give me a mountain of information. But what the heck is code and data? If I type c code into google I'M going to get a lot of c source code and I don't think that is what I'M ment to study here. If I type c data I suspect I'M going to find a lot of pages concerning data types. When looking at the four secments of c, how can I research code & data? Thanks.
