access voilation error

[oconv]

Hi All,

I'm not a regular C++'er , so maybe this will be easy.

I have 3 classes Driver , Savings & Customer.
Savings public inherits Customer.
The varibles in Customer is CustNumber (char*)
CustName, (char*)
CustTelNo. (long)

The Savings class has a constructor that accepts a char* it looks like this :

Savings(char* TempCustNum):Customer(TempCustNum){};

and then the Customer Constructor looks like this:

Customer(char* TempCustNum){
CustNumber = TempCustNum;
cout << &quot;Enter the Customer number&quot;;
cin >> CustName;
}

so this is what happens

In the driver I ask for a customer number , get it & then
constuct a instance of the savings class with the number that i just got from the user , the Savings class's constructor then calls the Customer class constructor , withc then set the CustNumber varible , & then asks for a Name , this is where the error steps in the moment I press Enter after I typed in the Customer Name

It goes back to the Borland compiler with a message box and says something about a execption error occured & give some memmory adress.

PLEASE HELP ME OUT OF MY MISSERY , I have no idea what to do. :-(

Thanks

Have you reserved some memory for the name ?
With char* you only have a pointer that has to point
to a location in memory where there is reserved space for the name. If you do not allocate memory , the pointer contains garbage.
Instead of char*, take char[256] for your name.
Then you don't have to worry about freeing it either when it is no longer used.
