1.0 INTRODUCTIONTechnology today has become relevant in every sphere of life with its applications bringing about an ease in the way we carry out our day to day activities. This has led to an introduction of computerization in most regular activities such as mathematical calculations which in turn brings about a greater rate of accuracy and efficiency in these so called mathematical calculations. This program is console based and is meant to receive input from the user of the x, y and z co-ordinates of two points and then go ahead to calculate the distance between these two points in both 2D and 3D, and to plot these points on the console
