I'm trying to pass a character as parameter into a function. I will then get the user's input( characters and numbers etc), the function then will return all the input characters excluding everything else. I've gotten the sorting the characters from everything else figured out, but returning the array back to the main function is my main concern.
first attempt: pointers!
problem: having trouble storing the values from the address of the pointer into another array.
second attempt: ...... not sure what to do next.
