Language/Type: C strings return
Author: Marty Stepp (on 2016/09/25)

Write a function named repeat that accepts a string (as a char*) and a number of repetitions as parameters and returns a heap-allocated string representing the parameter string concatenated that many times. For example, the call repeat("hello", 3) returns a new string "hellohellohello". If the number of repetitions is 0 or less, an empty string ("") should be returned. (You do not need to free any memory.)
