Casting

• Syntax:

      (new type)variable;
  

• Aritmetic casting is automatic.
• You may be explicit about casting to get desired results.
• Casting between structs, unions and other types is not allowed.

Casting between pointers

• All pointers except pointers to functions are the same size.
• Casting to a type void * and back is always valid.
• Casting between any other type is not guaranteed.
