Solution 1
| float literals | double literals |
| The float literals has a limited range to store decimal data items. | The double literals has a wider range as compared to float to store decimal data items. |
Solution 2
Floating point literal is a fractional number with short precision and the values can range from -3.4E+38 to 3.4E+38, whereas double type literal is used for long precision and the values can range from -l.7E+308 to l.7E+308.

Design a class to overload a function area( ) as follows:
(i) double area (double a, double b, double c) with three double arguments, returns the area of a scalene triangle using the formula:
area = `sqrt ("s" ("s" - "a")("s" - "b")("s" - "c")) "2ab"`
