When is it worth to create function in C?

Question

Is it a good practice to create function in C for every block of code that you need to evaluate more than once in your programm? Or maybe it is a wasting of memory and sometimes you can just copy some loops without creating function? I don't know how functions influence on the machine productivity.

Answer 1

i'm choosing the functions. it's better for readability, scalability and if you call them with pointers you gain at memory usage in some scenarios.

Answer 2

Yes, make a function whenever you might need to repeat the same block of code.
