Each image in the animation is called a "frame." Suppose that you have a subroutine static void showFrame(int frameNum) that displays one frame in an animation. That is, showFrame(1) displays the first frame, showFrame(2) displays the second frame, and so on. Suppose that there are a total of thirty different frames. How many frames will the following code display?: for (int play = 0; play < 10; play++) { for (int i = 1; i < =30; i++) showFrame(i); } Select one: a. 30 frames repeated 10 times b. 310 frames c. 10 frames d. 30 frames Question 8 Not yet answered Marked out of 1.00 Not flaggedFlag question Question text True or False: A for loop can use a list structure such as an enum to iterate the for loop? Select one: True False Question 9 Not yet answered Marked out of 1.00 Not flaggedFlag question Question text True or False: The break loop when encountered will cause processing to skip to the beginning of the loop? Select one: True False Question 10 Not yet answered Marked out of 1.00 Not flaggedFlag question Question text True or False: The continue statement when used in a loop will cause the flow of process to skip to the end of the loop and begin another iteration of processing? Select one: True False Question 11 Not yet answered Marked out of 1.00 Not flaggedFlag question Question text True or False: A for loop is used when the number of iterations through the loop in known in advance? Select one: True False Question 12 Not yet answered Marked out of 1.00 Not flaggedFlag question Question text True or False: The while loop is used when a known, finite number of loop iterations is required. Select one: True False Question 13 Not yet answered Marked out of 1.00 Not flaggedFlag question Question text True or False: The conditional expression in a while loop can be any expression that evaluates to a logical True or False? Select one: True False Question 14 Not yet answered Marked out of 1.00 Not flaggedFlag question Question text True or False: The while loop repeats a set of code while the condition is false. Select one: True False Question 15 Not yet answered Marked out of 1.00 Not flaggedFlag question Question text True or False: The do-while loop repeats a set of code at least once before the condition is tested. Select one: True False Question 16 Not yet answered Marked out of 1.00 Not flaggedFlag question Question text True or False: The for loop continues while a condition is true, and ends when that condition becomes false.
