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

where a$,$ b$,$ and c are the lengths of the sides, and s is the semiperimerter.

Write a void function that uses three parameters: two reference parameters and one value parameter. All three parameters provide the lengths of the edges, but the two reference parameters can return the area and perimeter $($not the semiperimeter$).$ 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. Then output the area and perimeter.
