Problem 4. (Lastname_Lab2_p4.cpp) Write a C++ program that will compute the distance between two points in a three dimensional space. [Hint: distance = (X2 x1)2 + (Oz - y)2 + (22 21)?] Following should be the prompt and output of the program: Enter the co-ordinates of first point (x1, yi, zl): 000 Enter the co-ordinates of second point (x2, y2, 22): 111 Distance between two points is: 1.73205
