Programming and data structures revision

What is an algorithm?

• A piece of a computer program.

• Something drawn on paper.

• A step by step instruction of how to solve a particular problem.

• A programming language.

What is compilation?

• The process in which a program in a programming language is translated into machine code line by line.

• The process in which a program in a programming language is translated into machine code as a whole.

• A collection of computer programs.

• A collection of programming languages.

What is interpretation?

• Analyzing a computer program.

• The process in which a program in a programming language is translated into machine code as a whole.

• The process in which a program in a programming language is translated into machine code line by line.

• A philosophical approach to computing.

How can an algorithm be represented?

• As a flowchart.

• As a programming language.

• As pseudocode.

• All the answers are correct.

What is a variable?

• A function in Python.

• A value within a program that can be changed.

• A way to represent an algorithm.

• A value within a program that cannot be changed.

What is selection in computing?

• It's the same as a loop.

• It's having to choose which programming language to use.

• It's where the program can produce different results depending on some condition.

• It can be either good or bad.

What is iteration in computing?

• It's a conditional statement.

• It's where the program can repeat some instructions.

• It's the name of a programming language.

• It's a way to represent an algorithm.

What types of iteration do you know?

• Definite - where we know how many times the loop wirll run.

• Indefinite - where the number of turns of the loop depend on the data.

• Infinite - that run forrever unless interrupted.

• All the answers are correct.

What is a flowchart?

• It's a way to visually represent an algorithm where different shapes of blocks represent different operations.

• It's a way to trace how variables change while running the program.

• It's how computers understand programming languages.

• It's a visual programming language.

What is pseudo-code?

• It is a plain language description of the steps in an algorithm. It uses the structures of a programming language but is intended to be read by humans.

• It's a programming language that is the closest to how computers operate.

• It's a programming language that is the closest to how chumans operate.

• It's an imaginary programming language.
