The problem asks for the output of a given pseudocode. The pseudocode initializes variables $a$ and $c$, then enters a repeat-until loop where $c$ is incremented and $a$ is updated based on the new value of $c$. The loop continues until $c > 3$. Finally, the value of $a$ is printed.

1. Problem Description

The problem asks for the output of a given pseudocode. The pseudocode initializes variables $a$ and $c$, then enters a repeat-until loop where $c$ is incremented and $a$ is updated based on the new value of $c$. The loop continues until $c > 3$. Finally, the value of $a$ is printed.

2. Solution Steps

We will trace the execution of the pseudocode to determine the final value of $a$.

Initial values:

$a = 5$

$c = 2$

Loop 1:

$c = c + 1 = 2 + 1 = 3$

$a = a + c = 5 + 3 = 8$

Condition: $c > 3$ is $3 > 3$, which is false. The loop continues.

Loop 2:

$c = c + 1 = 3 + 1 = 4$

$a = a + c = 8 + 4 = 12$

Condition: $c > 3$ is $4 > 3$, which is true. The loop terminates.

The value of $a$ is printed.

3. Final Answer

The final answer is
