Memory allocation for char array

Question

I have a big problem with C language when it comes to strings, char * \'s or whatever... So in this particular case I have a huge problem. I want to create an array

Answer 1

There are two ways of solving this issue.

Method #1: Use a maximum size to define your array. Here's what the code looks like:

char test[max_size];

You then need to keep track of how many elements are actually used up. This is used commonly in some old-school networking code.

Method #2: Use dynamic memory. Note that there is a bit of a performance issue here (potentially) since you have the ask the OS each time for a chunk of memory. There is an answer up here already that shows you how to do this. Just be sure to call free() once you are done using your array.
