Question

The area of an arbitrary triangle can be computed using the formula
area =

where a, b, and c are the lengths of the sides, and s is the semiperimeter.
s = ( a + b + c ) ⁄ 2
Write a void function that uses five parameters: three value parameters
that provide the lengths of the edges, and computes the area and
perimeter (not the semiperimeter) via reference parameters. Make your
function robust. Note that not all combinations of a, b, and c produce a
triangle. Your function should produce correct results for legal data and
reasonable results for illegal combinations.
