But most people who start out with "The C Programming Language" and never read "Design Patterns" will only ever use for loops and never think about iterators. How do you want to transmit certain concepts without giving them names? I also had situations where "Design Patterns" helped me find a solution. Of course I also experienced the IT Manager who wanted to see Design Patterns everywhere, no matter if they were useful or not. But that is not the fault of the book.
