Answer 1

To determine how many total times Karel will move in the given program, let's break down the code step by step:

1. The function main starts and Karel will first execute the move() function outside of any loop:

   • This is the first move: 1 move.

2. Next, there is a for loop which runs 5 times:

   • Inside the loop, Karel executes move() and putBall() in each iteration. The putBall() function does not involve movement, so we only count the move() calls.
     • In each iteration of the loop, Karel moves 1 time. Since the loop runs 5 times, the total moves in this loop will be:
       • 5 moves (1 move for each of the 5 iterations).

Summing it all up:

• Initial move before the loop: 1 move
• Moves during the loop: 5 moves

Total moves = 1 + 5 = 6 moves.

So the answer is 6.
