C++ PROGRAMMING HELP!!!
Hello, i need help completing a program.. myStringClass.cpp was created and i need help to fix it. Error: "static void validateUserInput(myStringClass& myStringClassObject);" in the myStringClass.h; line 66 is not in the myStringClass.cpp file and i need help implementing it into myStringClass.cpp. So in short: Please complete the myStringClass.cpp by adding the code to "static void validateUserInput(myStringClass& myStringClassObject);". I'm getting an error without it...
I have provided main.cpp and myStringClass.h below. PLEASE DO NOT CHANGE ANYTHING IN THOSE FILES. I also attached the myStringClass.cpp below and a screenshot of the completed program. Any and all help is GREATLY appreciated!! Please and thank you so much in advanced.
--------------------------
FULL PROMPT:
Write your own string class (almost), the following are the requirements:
Use the enclosed .h and the enclosed main.cpp files (main.cpp & myStringClass.h)
Define each of the declared functions in the .h file. Comment your code & use meaningful or mnemonic variable names
--------------------------
RESTRICTIONS:
NO global variables | NO labels or go-to statements | NO infinite loops | NO break statements
DO NOT #include in any of your files; in other words, do NOT use the string class
MAY USE string literals, but do NOT use variables of type string.
