Hi,
I have some excercises about strings to concadenate, copy strings and sorting using pointers and functions but I am not able to start. Let me to explain, I barely know how to do that in int main () but not using custom functions, I am completely lost at this point. Is there any book or tutorial that explain this? I have been looking for tutorials but most of them solve those problems in int main(). I think a book may be a better solution.
Thank you in advance.
