Which of the following images shows the path and ending location of the robot that will result from executing the code above. The starting location of the robot is shown as dotted triangle for cases where the robot does not start and end at the same location.

REPEAT 4 TIMES {

MOVE_FORWARD()

MOVE_FORWARD()

MOVE_FORWARD()

ROTATE_RIGHT(90)

MOVE_FORWARD()

ROTATE_RIGHT(90)

MOVE_FORWARD()

Consider the following incorrect program, which is intended to move the robot around the perimeter of a grid, as indicated by the drawing below. The starting position and direction of the robot is indicated in the diagram.

Line 1: 4 TIMES

Line 2: {

Line 3: MOVE_FORWARD()

Line 4: ROTATE_RIGHT()

Line 5: MOVE_FORWARD()

Line 6: MOVE_FORWARD()

Line 7: MOVE_FORWARD()

Line 8: MOVE_FORWARD()

Line 9: ROTATE_RIGHT()

Line 10: }

Given the options below, which lines should be removed so the program will work as intended?

• Line 3 and Line 4

• Lines 5, 6, 7, 8 and 9

• Line 8 and Line 9

• Line 9

Which of the following is NOT true about functions in programming?

• Functions are reusable programming abstractions.

• Functions help reduce the complexity of writing and maintaining programs.

• Functions cannot make calls to other functions within the same program.

• Once defined, a function can be called many times from different parts of a program.

• Functions help break a problem into logical chunks.

What is one important naming convention of functions?

• A function name should indicate how long the function takes to run.

• Two functions with similar behavior should be given identical names to indicate the relationship between them.

• A function name should be as descriptive as possible to indicate what the function does.

• Function names should be organized alphabetically.

• The function name should begin with a number that indicates the order in which it should be executed.

Which one of the following statements about functions is TRUE?

• A function can change names over the course of a program.

• Code can be added or removed dynamically from a function while the program is running.

• Functions can be called using different names depending on where in the program they are called.

• Two functions can be given identical names as long as their code is identical.

• Two functions in a single program can have different names but contain identical code.

 Pulling out specific differences to make one solution work for multiple problems.

• Top Down Design
• Abstraction
• variable
• none of the above

For this scenario related to turtle drawing, indicate whether it is better to write a loop or a function (or a set of functions) to handle the task:
