Dev Corner - Cast Operator
Posted on Friday October 28, 2011 by Randall Brown
Today's Dev Corner post is brought to you by AJ Orians.
The cast operator is not well known so I'll explain what it is and how it can be used. To start off POD stands for Plain Old Data in C++ which is things like int, char, double, etc. Unfortunately you cannot inherit off of such datatypes. One advantage of inheriting is you can cast to the base type (assuming public inheritance). With the cast operator you'll be able to specify types that your object can cast to. Below is a simple example showing how the cast operator works:
As you can see I am able to cast the object of type A to an int type. Do you now understand the cast operator? Do you see yourself having a use for it? Let me know what you think!
