E7.16 Define a structure Point. A point has an x- and a y- coordinate. Write a func- tion double dis- tance(Point a, Point b) that computes the dis- tance from a to b. Write a program that reads the coordinates of the points, calls your function, and displays the result. E7.17 Using the point structure from Exercise E7.16, write a function Point midpoint (Point a, Point b) that computes the point that is halfway be- tween a and b. Write a program that reads the coordinates of the points, calls your function, and displays the result. R7.2 Trace the following code. Assume that a and b are stored at 20300 and 20308. Your trace table should have entries for a, b, p, and q. double a = 1000; double b = 2000; double* p = &a; double* q = &b; *p = *q; p = 9; *p 3000
