Fundamental Data Types − Integer (Part 2)


Today we will continue our discussion on integer data type. Our outline for today
's would be to study modifiers such as short , long signed , unsigned and some
programming examples. These are the modifiers used to make it possible for a data
type to take less or more memory. It is not guaranteed that short takes lesser
memory than the integer and long takes more memory than an integer. By default, by
default integer is signed integer in our systems. In my system, the size of integer
is of 4 bytes. In the second example, we are trying to print the range of unsigned
integers. There is no symbolic constant available in limits. h header file for
minimum value of unsigned integer. Minimum value is fixed for all systems and that
is zero. Writing signed int some_variable_name; is equivalent to writing int some.
variable_name. to sizeof ( int ) and is less than or equal to sizeof. (long)
Writing signedint some_variety_name ; is equivalent. to unsigned long integer ''
which is actually equivalent to signed long integer.
