I need to brush up on C for my dissertation. How does this compare to Head First C? I read the first chapter of that book and loved it! Very unlike other books on C which dedicate an entire chapter to `for` loop for instance. How do other programmers even read a book like that? Isn't it tiring to read through how a `for` loop works for the 70th time.
