Question
I'm using C++ to build a credit card simulator. My code is already completed, however I am getting three error messages on my CreditCard.h file. The three error messages are
error C2327: 'CreditCard::lim' : is not a type name, static, or enumerator
error C2065: 'lim' : undeclared identifier
error C2864: 'CreditCard::bala' : only static const integral data members can be initialized within a class
Here is the link to my project file. I am using Microsoft Visual Studio 2012 to write this code, and am absolutely stuck on how to fix the problem. Please fix the errors so that the program compiles and runs correctly. You can simply post the code snippet that you changed if you prefer. Be sure the code compiles without error.

Explanation / Answer
You are getting the error because you are trying to initialize the class member variable bala in its declaration. Class member variables need to be initialzied in constructor or any other method as applicable. So I have initialized bala in the constructor. The fixed code is given below . I tried to run the program , but looks like the functionality is not yet in place. None of the menu options were functioning as the name suggests.
I AM GIVING ONLY THE PART OF THE CODE THAT WAS FIXED. Please rate if the answer helped. Thank you.
