Main function error

[Soko San]

Sorry for bothering :( but another error happened when I tried to write the main function.
It says : error C2228: left of '.getLoadFactor ' must have class/struct/union type

Not calling loadfactor is the only problem but when I try to call any one of them (insert,remove. ..)
Anyone know what this mean? And especially HOW to fix it??

The error is here:

HASH STUDENT();

This is a call to the HASH default constructor. The compiler creates a temporary HASH object for this statement, calls the HASH constructor, and then deletes the temporary object at the end of the statement.

Just do this:

HASH STUDENT;

This tells the compiler to create a local variable of type HASH named STUDENT and then to call the default HASH constructor to initialize the variable.

Ok I did what u said the error has gone but a run time error has happened why???? is there anything wrong with my array??? what should I do??

Can u show how to write a good main function to test this implementation? ?

Probably you are going outside the array bounds.

There are no checks in your code to make sure you are inside your array.

My first suggestion is to use std::string instead of arrays. std::string has all the protective code needed to stay inside the array used by std::string.

Otherwise, you step through the code using your debugger to see where the crash occurs.

As to testing, that's a big subject. I would suggest that you test using data that you know is smaller than your arrays. When you get it working this way, then you can provide data designed too provoke a crash.
