Pseudocode and Problem Solving Quiz

Which of the following is a correct characteristic of an algorithm?

• Always infinite

• Vague steps

• Step-by-step process

• Written in natural language

Consider the following pseudocode and determine how often the loop is iterated: i = 0 while i < 10: i = i + 1

• 6

• 8

• 9

• 10

Assertion (A): Algorithms must have a finite number of steps. Reason (R): An infinite loop in an algorithm helps in solving complex problems.

• Both A and R are true, and R is the correct explanation of A

• Both A and R are true, but R is not the correct explanation of A

• A is true, but R is false

• A is false, but R is true

Assertion (A): Flowcharts are used for representing algorithms. Reason (R): Flowcharts help in visualizing the logic of a program.

• Both A and R are true, and R is the correct explanation of A

• Both A and R are true, but R is not the correct explanation of A

• A is true, but R is false

• A is false, but R is true

Which of the following ensures that an algorithm terminates?

• Input/output

• Finiteness

• Efficiency

Which of these is NOT a method of representing an algorithm?

• Flowchart

• 6

• 5

• 4

• 3

Assertion (A): Pseudocode must follow strict programming syntax. Reason (R): Pseudocode is meant to be compiled directly.

• Both A and R are true, and R is the correct explanation of A

• Both A and R are true, but R is not the correct explanation of A

• A is true, but R is false

• A is false, but R is true

Assertion (A): Testing helps verify the correctness of a program. Reason (R): Errors identified during testing can be debugged.

• Both A and R are true, and R is the correct explanation of A

• Both A and R are true, but R is not the correct explanation of A

• A is true, but R is false

• A is false, but R is true
