ASSIGNMENT 5 Weight 20
------------ Due 7 March 90
You are given eight sets of three values each:
23.37 19.51 8.37
57.46 40.06 27.57
42.09 35.78 61.65
8.63 15.74 12.38
61.94 78.07 10.87
19.56 23.54 33.28
84.37 61.98 15.93
37.80 49.24 23.51
Write a Pascal program to determine if the three values of a
set could represent the lengths of the sides of a triangle. If the
three sides could make a triangle, calculate its area and print a
message like:
When AB=3.00 and BC=4.00 and CA=5.00,
the area of triangle ABC is 6.00
If a, b, c are three side lengths, then the area is
SQRT( (s(s-a)(s-b)(s-c)) )
where s is the half perimeter (a+b+c)/2
(the formula is due to Hero, a mathematician of ancient times.)
If the three values in a set could not represent the sides of a
triangle, print a message like
23.37, 19.51, and 9.37 could not possibly be the sides of a
triangle
A property of Hero's formula: if s(s-a)(s-b)(s-c) is negative,
then a, b, c can't make a triangle.
Please MAKE SURE YOU PUT your name, student #, and assignment #.
Also, put some comments on your code so that the grader can
figure out what you are doing. It helps to have meaningful
variable name, like AREA instead of X for a variable containing an
area value.
