accessing varible in a c++ class

I have a program that is trying to access a varible from a class in a porgram. For example

the varible customer is my Account.h file and in my Bank.h I have another varible called Account savings, they are both arrays.

In my Bank.cpp file I have to take the info from Account savings and put in the customer varible.

the line of code looks like this

savings[pos].customer[j]=c[m];

and I get the error something like
can't access the private member varible

What is the problem, keep in mind that I have added the includes for Account.h and Bank.h in Bank.cpp

Thanks

Make sure that the member variable is public.

I'm not going to attempt the syntax off the top of my head, but... Somtimes I've had to pass a pointer-to-an-object into a member function in another class. Make sure all of your variables are in-scope. All the variables that your function uses have to be passed-into the function (directly, via pointers, or via references).

And, it's usually considered better to make the member variables private, and provide a public accessor function, which is a public member function that returns the particular variable, rather than directly accessing the member variable.
