https://technotip.com/7997/c-program-to-calculate-area-of-a-triangle-using-pointers/

Lets write a C program to calculate area of a Triangle when their sides are input by the user. Lets use pointers and functions.

Problem Statement If the lengths of the sides of a Triangle are denoted by a, b and c, then area of Triangle is given by:

area = sqrt( S * (S – a) * (S – b) * (S – c) );

where, S = (a + b + c) / 2. Write a function to calculate the area of the Triangle.

Here S is semi-perimeter of the Triangle.
