Pointers - variables that store a location


Write a line of code that declares a pointer to an integer.

I have already declared two pointers to integers, x and y, 
  and two integers, i and j.
	Write a line of code that assigns x to point to j.
	Write a line of code that assigns y to point to i.
	Write a line of code that places the number 8 into j. x is the only 
		variable that can be on the right side of the assignment 
		operator.
	Write a line of code that points x to i. y is the only variable that 
		can be on the right side of the assignment operator.


Write a function, calc_stats, that returns several values. 
   It takes an array (and a length)
   and calculates the average, median, and standard deviation.
	Write the prototype of this function.
	Write it in such a way that the values in the variables in the caller's
	space are changed (rather than only the inputs to the function).
Write code in main that does everything necessary to use calc_stats properly.
