Exercise 1 Develop a data definition ManyNumbers which can store arbitrarily many numbers. Exercise 2 Develop a data and structure definition for storing pairs of numbers representing x and y coordinates. Exercise 3 Develop a data definition ManyPairs which can store arbitrarily many pairs of numbers using the data definition from the previous exercise. Exercise 4 Write the templates for all of the three data definitions you have defined. Exercise 5 Design a function, which, given ManyPairs, draws all of the points as circles with radius 10 on the same empty scene, producing the resulting image. Exercise 6 Design a function, which, given ManyPairs and two numbers for x and y coordinates, creates a larger ManyPairs with all of the coordinates plus the new pair of coordinates. Exercise 7 Using the functions you developed in exercise 5 and 6, design a big-bang program which places a circle on every mouse event at the location of the mouse event. Note that this is similar to, but not exactly the same as, the Challenge Exercise from |
