Desk Checking and Pseudocode Quiz

What is desk checking in programming?

• A method of debugging code using automated tools

• A process of manually tracing through an algorithm to verify its logic

• A technique for writing pseudocode

• A way to optimize code for better performance

Given the pseudocode below, what will be the final output?

START

SET sum = 0

FOR i = 1 TO 3

SET sum = sum + i

ENDFOR

OUTPUT sum

• 3

• 0

• 6

• 9

In the pseudocode below, what is the value of 'sum' after the second iteration?

START

SET sum = 0

FOR i = 1 TO 3

SET sum = sum + i

ENDFOR

• 1

• 3

• 0

• 6

What is wrong with the following pseudocode?

START

FOR i = 1 TO 3

SET sum = sum + i

ENDFOR

OUTPUT sum

• The pseudocode uses incorrect syntax for the loop

• The output statement is missing

• The variable 'sum' is not initialized

• The loop is missing an end condition

Why is desk checking useful before writing code?

• It ensures the algorithm is logically correct

• It helps identify syntax errors in the code

• It eliminates the need for debugging

• It speeds up the coding process

What is the primary purpose of pseudocode?

• To represent algorithms in a human-readable format

• To execute code without a compiler

• To debug programs efficiently

• To optimize code for performance

Which of the following is a characteristic of desk checking?

• It requires a computer to execute the algorithm

• It involves manually tracing through the algorithm

• It is a method for writing pseudocode

• It is used to optimize code for speed

What will be the output of the following pseudocode?

START

SET count = 0

FOR i = 1 TO 4

SET count = count + 2

ENDFOR

OUTPUT count

• 4

• 6

• 10

• 8

In the pseudocode below, what is the value of 'count' after the third iteration?

START

SET count = 0

FOR i = 1 TO 4

SET count = count + 2

ENDFOR

• 8

• 6

• 2

• 4

What is wrong with the following pseudocode?

START

SET total = 0

FOR i = 1 TO 5

SET total = total + i

OUTPUT total

ENDFOR

• The output statement is inside the loop

• The variable 'total' is not initialized

• The loop range is incorrect

• The loop is missing an end statement
