Hello,I've used google for more information about what I'm going to ask for, but I still need a real help to know much about the term "Modularity in C programming" even what's about?, what actually the function "strcopy()" do stand for ?, also the functions "malloc" and "free" I dont actually know why we use them and how can we use them through the code...if you can give an example about "malloc" and "free" then would be nice and appreciated much .
P.S: if there's any video explaining the subjects that I demanded about as please link me them over here.
thanks beforehand.
