The area of an arbitrary triangle can be computed using the formula
area = √(s(s–a)(s–b)(s–c))
where the square root is applied to the entire product and where a, b, and c are the lengths of the sides, and s is the
semiperimeter of the triangle given by the formula:
s = (a + b + c)/2
Write a void function named triangle that computes the area and perimeter (as well as the semiperimeter (which will be used to compute the area)
of a triangle based on the length of the sides. The function should use five parameters and may call other functions.
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. Include in your submission a driver that repeatedly reads in 3 positive numbers that
are the sides of a triangle, and each time print out the sides and the area and perimeter calculated by the triangle function. Your program should
terminate when the first side typed in a group of three is negative or zero.
