2:08:53nick_19992 Q: Hi, I'm waiting for your Star Code Galaxy¹, but meanwhile, reading K&R.² Do you think I should be able to solve all exercises one by one or I could skip them and continue with the text and get back to them later? For example, before chapter one there's an exercise to remove comments from a C program and I'm having trouble to solve it at this stage. Thank you
