A pointer pointer needs a pointer pointer
I am getting this error, Indirection requires a pointer-pointer ('int invalid') in this code, I think I am using empPtr incorrectly in this code, but I am not sure.
Thanks in advance guys.
I will also include my other classes from this link. https://gist.github.com/anonymous/08ff6c5284c179c9a323
My input text file looks like this.

This line is incorrect.
Employee empPtr = employeeArray[50];
The maximum allowed index for employeeArray
is 49
.
To get the first element of an array use:
Employee empPtr = employeeArray[0];
To get the last element of an array use:
Employee empPtr = employeeArray[49];
