I know just what you mean! When I was learning to use CodeBlocks for C/C++ programming, I also wasn't able to read the code at all. I managed to do the exercises but only because I was coppying the code and changed only a few things. But when later I did more and more of those exercises, I kinda started to be able to read the code. I wasn't very good at it but I know that you'll be able read the code as you continue to do exercises.
