Every
programming language support inbuilt data type or primary data type which is already
available in the programming language.
The primary data types themselves could
be of several types namely signed or unsigned. The maximum value hold by a data
type depends upon the number of bytes it occupies in memory. for example char
data type occupies 8 bit and it store -128
to 127.
Primary
data types are as follows:
