Write an empty main function. Write a function called max() that
accepts 3 doubles and returns the maximum value of the three. Add
code to your main function to test your code. Use all permutations
of 1, 2, and 3 (1,2,3) (1,3,2) (2,1,3) (2,3,1) (3,1,2) (3,2,1). The
output below proves that max finds the max of the three for all of
the required test data.
Output
max = 3.00
max = 3.00
max = 3.00
max = 3.00
max = 3.00
max = 3.00
