This determines the type and size of data associated with variables. The c compiler combines the capabilities of an assembly language with the features of a highlevel language and therefore it is well suited for writing both system software and business packages. In machine language, there are no if statements or loops we only have branches, which can be either unconditional or conditional on a very simple condition with this, we can implement loops, if statements, and case statements.
