G11 CS Algorithm and Computational Thinking

What is an algorithm?

• A programming language
• A sequence of defined steps to solve a problem
• A mathematical formula
• A pattern or behavior of the internet user's activity

What is the purpose of an identifier table in programming?

• To identify the data used in a problem
• To organize the code
• To create a user interface
• To debug the program

What are the three basic constructs of pseudocode?

• Sequence, Selection, and Iteration
• Input, Process, and Output
• Assignment, Functions, and Loops
• Selection, Arrays, and Loops

What is the purpose of using pseudocode?

• To communicate the logic of a program to others
• To translate code into a different programming language
• To test the accuracy of a program
• To create a user interface

What is the first step in writing pseudocode for a problem?

• Defining the input
• Creating the identifier table
• Outlining the process
• Identifying the output

Which of the following is an example of a suitable identifier name for a variable in a program?

• xyz
• 123
• user_input
• variable1

How does the use of iteration in pseudocode affect the program?

• It allows for repetitive actions to be performed
• It changes the input of the program
• It alters the output of the program
• It affects the process of the program

What is the purpose of using the construct of selection in pseudocode?

• To make decisions based on certain conditions
• To repeat actions multiple times
• To change the input of the program
• To organize the code

What is the difference between a sequence construct and an iteration construct in pseudocode?

• A sequence construct performs actions in a specific order while an iteration construct repeats actions
• A sequence construct changes the input while an iteration construct changes the output
• A sequence construct is used for selection while an iteration construct is used for repetition
• There is no difference, they are the same thing

How does the use of pseudocode affect the final program?

• It helps to communicate the logic of the program to others
• It makes the program run faster
• It makes the program more visually appealing
• It has no effect on the final program.
