hi, i'm having problems with my homework. I have to create a Base classes from which 2 classes have to be derived, then i have to write a program to test their function. The problem that i'm having is that i'm taking the input from the keyboard and passing it to a function in the base class. I dont get any error/warning messages but when i run the debug, it stops when it takes the first keyboard input. Programs stops when the input from line 33 (when B/b is selected) or 47 (when R/r is selected), of the Library.cpp file, is copied on the Holding.cpp file line 28 "strcpy_s(title, strlen(name), name)." Any suggestion on what could it be????
