Question

Look at the following pseudocode. If it were a real program, what would it display? Declare Integer counter = 1 Constant Integer MAX = 7 While counter <= MAX Display counter Set counter = counter + 2 End While

Short answer

Answer: The output would be: 1 3 5 7

Step-by-step solution

1. Declare Variables and Constants

In the pseudocode, we have two declarations: the Integer variable named "counter" with an initial value of 1, and the Constant Integer named "MAX" with a value of 7.

2. While Loop

The While loop will be executed as long as the condition "counter <= MAX" is True. This means that the code within the loop will be executed repeatedly until "counter" becomes greater than "MAX".

3. Loop Execution

Inside the loop, we have two lines of code: - Display counter: This line prints the current value of the "counter" variable. - Set counter = counter + 2: This line increments the "counter" variable by 2 each time the loop iterates.

4. Analyzing Loop Iterations

Let's see how the value of "counter" changes in each iteration and when the loop will stop: - Iteration 1: counter = 1 (1 <= 7, condition True; Display 1, counter becomes 3) - Iteration 2: counter = 3 (3 <= 7, condition True; Display 3, counter becomes 5) - Iteration 3: counter = 5 (5 <= 7, condition True; Display 5, counter becomes 7) - Iteration 4: counter = 7 (7 <= 7, condition True; Display 7, counter becomes 9) In the next iteration, since counter is 9 and 9 is not less than or equal to 7 (condition becomes False), the loop will stop executing and the program will end.

5. Output

Based on the loop iterations, the loop will display the following values for the "counter" variable in order: 1, 3, 5, and 7. So, the output of the pseudocode would be: 1 3 5 7
