Write a program which reads in a dynamic array of floats from the user.

You should have a function for input, a function to compute the
average, a function to compute the minimum and a function to compute
the maximum.  You should use dynamic arrays and pass a pointer of the
array to a function.

Once your program is complete and verified that its working, trace the
program with a memory diagram. Do you handle all memory and pointers
appropriately?
