Chapter 3, Problem 2PP

General math) a. Write a C++ program to calculate and display the midpoint coordinates of the line segment connecting the two endpoints given in Exercise 1a. Use the fact that the coordinates of the midpoint between two points with the coordinates $x1,y1)and\left(x_2,y_2\right)are\left(\left(x_1+x_2\right)/2,\left(y_1+y_2\right)/2\right).$ Your program should produce the following display (replacing the underscores with values your program calculates):

$\begin{array}{l}Thexmidpointcoordinateis\_\_\_\_\_\hfill \\ Theymidpointcoordinateis\_\_\_\_\_\hfill \end{array}$

b. How do you know the midpoint values your program calculates are correct?

c. After verifying the output your program produces, modify it to determine the midpoint coordinates of the line connecting the points (2,10) and (12,6).

d. If your program doesn’t already do so, change its output to this:

The x coordinate of the midpoint is xxx.xx

The y coordinate of the midpoint is xxx.xx

The xxx.xx denotes placing the calculated value in a field wide enough for three places to the left of the decimal point and two places to the right of it.
