Answer 1

Let's analyze the program step by step to determine how many times Karel will move.

1. The first line in the main function is move();, which means Karel will move once.
2. Then, there is a for loop that iterates 5 times:
   • Inside the loop, Karel executes move(); and putBall();. The putBall() function does not affect the movement count.

Within this loop:

• For each iteration, Karel moves once.

Since the loop runs 5 times, Karel will move 5 more times during this loop.

Now, we can total the moves:

• 1 move before the loop (the initial move())
• 5 moves during the loop (one for each of the 5 iterations)

So, the total number of moves is: 1 (initial move) + 5 (moves in the loop) = 6 moves.

Therefore, the answer is 6.
