Answer 2

Value of Variable P:

The initial value of variable P is 13. After executing the given program fragment, the value of P will be 10.

The program fragment starts with the assignment P:=13. Then, it enters a while loop with the condition P>0. Inside the loop, the value of P is decremented by 3 (P:=P-3). This process continues until the condition P>0 becomes false, which happens when P reaches 10. Therefore, the final value of P is 10.

Value of Variable L:

The initial value of variable L is 1. After executing the given program fragment, the value of L will still be 1.

The program fragment starts with the assignment L:=1. Then, it enters a while loop with the condition L<0. However, since the initial value of L is already greater than 0, the condition L<0 is false, and the loop is never executed. Therefore, the value of L remains 1.

Number of Times the Loop Body Executes:

For the given program fragment: ``` L:=10; WHILE L>0 DO L:=L-3; END; ``` The loop body will execute 4 times.

The program fragment starts with the assignment L:=10. Then, it enters a while loop with the condition L>0. Inside the loop, the value of L is decremented by 3 (L:=L-3). This process continues until the condition L>0 becomes false, which happens when L reaches 1. Therefore, the loop body executes 4 times.

Number of Times the Loop Body Executes (with the given header):

For the given program fragment: ``` K:=-1; WHILE K<3 DO K:=K+2; END; ``` The loop body will execute 2 times.

The program fragment starts with the assignment K:=-1. Then, it enters a while loop with the condition K<3. Inside the loop, the value of K is incremented by 2 (K:=K+2). This process continues until the condition K<3 becomes false, which happens when K reaches 3. Therefore, the loop body executes 2 times.

Value of Variable K:

The initial value of variable K is -1. After executing the given program fragment, the value of K will be 3.

The program fragment starts with the assignment K:=-1. Then, it enters a while loop with the condition K<4. Inside the loop, the value of K is incremented by 2 (K:=K+2). This process continues until the condition K<4 becomes false, which happens when K reaches 3. Therefore, the final value of K is 3.
