2. a. Write a C program to calculate and display the coordinates of the midpoint of the line segment connecting the points (3, 4) and (10, 12). Use the fact that the coordinates of the midpoint between two points having coordinates (x,yi) and (xy2) are (/x+x2)2 yi+ yo)/2). Your program should produce the following display: The y midpoint coordinate is where the blank spaces are replaced with the values calculated by your program b. How do you know that the midpoint values calculated by your program are correct? c. Once you have verified the output produced by your program, modify it to determine the midpoint coordinates of the line connecting the two points (2,10) and (12, 6)
