I have a question for C programming. I have a loop where I generate at each iteration a new char. Each generated char I want to append to a string (char *)

I am not good with c++ and I cannot find this anywhere, please apologize me if it is a bad question. I have a pointer and I want to know if some names store in this pointer begins with some specific s
I have a working example of a piece of C code that I\'m using to teach myself about using pointers effectively in a non-trivial application. (I have a dream to contribute a missing feature to a C libr
