(This is redoing of your previous homework problems. This time do this problem by using
user defined functions. Please create 3 script with 1) A User defined function that does not
take any argument and does not return any value. 2) A User defined function that takes
arguments but does not return any value. 3) A User defined function that takes arguments
and returns a value.
(USE ARRAY FOR THE Vertices and Lengths! ) Create a script that will take user input
of 3 vertices to calculate the area of a triangle by using Heron’ Formula. You will need
the “pow” function in “math.h” header file.
