INTEGRAL TYPES
The real types were the easy ones. The rules for the integral types are
more complex but still tolerable, and these rules really should be
learned.
Each programming language has in-built types to distinguish
between the nature of various data (input or output or intermediate).
Integer is a common data type which is extensively used in general
programming and in scientific computing.
Fortunately, the only types used in C for routine data storage are the
real and integer types, or structures and arrays built up from them.
C doesn't have exceptional types for character manipulation or the
handling of logical (boolean) quantities but uses the integral types
instead.
In C programming language, integer data is represented by its own
datatype known as int. It has several variants which differs based on
memory consumption includes:
int
long
short
long long
The minute you know the rules for the reals and the integers you
know them all. We will start by looking at the various types and then
the conversion rules.
PLAIN INTEGERS
int
Integers are whole numbers that can have both zero, positive and
negative values but no decimal values. For example, 0, -5, 10
We can use int for declaring an integer variable.
There are two types (often called ‘flavors’) of integer variables.
Additional types can be built from these, as we'll see, but the plain
undecorated ints are the base. The most obvious of the pair is the
‘signed’ int, the less obvious is its close relative, the unsigned int.
These variables are hypothetically to be stored in whatever is the
most convenient unit for the machine running your program. The int is
