types of output (windows, dialogs and so forth).
•These programs are called Windows applications
and provide graphical user interfaces.
•Console applications – applications that contain

Memory Concepts
•Variable names actually correspond to locations in
the computer’s memory.
•Every variable has a name, a type, a size, and a

•Example:
number1 = Int32.Parse( firstNumber );
number2 = Int32.Parse( secondNumber );
sum = number1 + number2;
