Programming Project 1

Due: Thursday, September 13th by 1:45pm

A point in a plain can be represented by giving it's x and y coordinates. A line segment can be represented by giving the two end points. A common task is to find the midpoint of a line segment given the two end points. The midpoint formula is given below:

Given two points (x₁, y₁) and (x₂, y₂) - the midpoint formula is:
x_m = x₂ + ((x₁ - x₂) / 2) and y_m = y₂ + ((y₁ - y₂) / 2)

Design, implement and test a C++ program that reads in two points (x and y coordinates) and calculates the midpoint of the line segment.

Sample program run:

Welcome to the midpoint calculator program!!

Enter coordinates for point 1 (x coordinate first): 3 3

Enter coordinates for point 2 (x coordinate first): -1 1

//output

With point 1 equal to (3,3) and point 2 equal to (-1,1)
The midpoint is (1,2).
Thanks for using the midpoint calculator
