Is learning C really a must for a programmer?

Many have this opinion. Somehow, by doing manual memory management allocation and garbage mangement one would become a better programmer.

I have little experience in C mainly because I can write terser and more readable code in Racket or Haskell. However I'm willing to give C a try just to learn these lessons that everybody keeps talking.

But I have a sneaking suspicion that I already know most of what is there to know. Can you list some useful lessons that a typical high level code dweller would be oblivious of?

You recorded data from a test. There is one file for each data channel recorded. The number of channels typically ranges from 2-250.

You need to compile a list of each channel name which is found in the header of each file. Suppose that the first line of the file is the channel name if you intend of offering some code.

How do you compile an array of strings that has each channel name in order? Go on, offer the best solution. It just seems like a perfect situation to dynamically allocate memory.
