In mathematics, the midpoint between the two points (x1, y1) and (x2, y2) is computed by the formula (1+x231 x1 + x2 1 + y2 2 Write a C++ program that receives two mathematical points from the user and computes and prints their midpoint. A sample run of the program produces Please enter the first point: (0,0) Please enter the second point: (1,1) The midpoint of (0,0) and (1,1) is (0.5, 0.5) The user literally enters "(0,0)" and "(1,1)" with the parentheses and commas as shown. To see how to do this, suppose you want to allow a user to enter the point (2.3,9), assigning the x component of the point to a variable named x and the y component to a variable named y. You can add the following code fragment to your program to achieve the desired effect:
