Chapter 3.3, Problem 5E

(General math) Write, compile, and run a C++ program to calculate the distance between two points with the coordinates (7, 12) and (3, 9). Use the fact that the distance between two points with the coordinates (x1, y1) and (x2, y2) is given by this formula:

$dis\tan ce=\sqrt{(x^2+y^2)}$

After verifying that your program works correctly by calculating the distance between the two points manually, use your program to determine the distance between the points (-12, -15) and (22, 5).
