Correct Answer : C
The range of the information to be stored must fall in range of any of the integer datatype (optimal).
Range of byte
: -128
to +127
Range of short
: -32,768
to +32,767
Range of int
: -2,147,483,648
to +2,147,483,647
Range of long
: -9,223,372,036,854,775,808
to 9,223,372,036,854,775,807
byte
and short
will not be suitable. int
and long
are suitable but using int
saves space.
