C-Language scalar type (RPM)

In the C language, the representation of enumeration types, character types, and various integers is called scalar types.

When you use a scalar-type value in a C expression, the compiler automatically converts those identifiers to integer saves.

The effect of this mechanism is that the operations performed on these scalar types are exactly the same as those performed on an integral type.
