Write a program to do the following: Ask the user for two (integer) coordinates in the x-y plane. Compute the distance between the two coordinates. Display the result. You must define and use at least the following three functions: main (of course) get_coordinate (no return, but two references to int that should be modified in the function) distance (four int arguments, x1, y1, x2, y2, returns distance between coordinates (a float)) Notes: Check the man pages for sqrt and pow. When testing on cisc210-roosen using the above, your compile line should include -lm Because get_coordinate needs to modify its parameters and have to modifications reflected in the calling function, the prototype should look like this:
