CS Edexcel 1.2a Writing Algorithms

What should you do when writing an algorithm?

• Focus on the output of the program
• Break the problem down into logical steps
• Use syntax to show all details
• Write it directly in a programming language

Why is it important to practice writing algorithms?

• To understand programming languages better
• To improve problem-solving skills
• To create complex software applications
• To memorise syntax rules

What is Pseudocode?

• A programming language

• A detailed algorithm

• A high-level description of an algorithm

• A type of software

What is pseudocode primarily used for?

• To create a visual flowchart
• To write algorithms in a language-independent manner
• To code directly in a programming language
• To document software bugs

What is the primary advantage of writing algorithms in pseudocode rather than in a specific programming language?

• Pseudocode can be easily understood by anyone regardless of programming knowledge.
• Pseudocode is faster to execute than any programming language.
• Pseudocode uses complex syntax that requires advanced programming skills.
• Pseudocode is limited to specific programming languages.

Which of the following is NOT a keyword commonly used in pseudocode?

• IF
• PRINT
• LOOP
• ELSE

What is the purpose of using flowcharts?

• To write code directly
• To visually represent the logic of a program
• To store data in a database
• To create user interfaces

What is the main benefit of using flowcharts when writing algorithms?

• They provide a visual representation of the logic
• They are written in a specific programming language
• They require no practice to understand
• They are more complex than pseudocode

A flowchart is a diagram that represents a process or algorithm using _____.

In a flowchart, what does this symbol represent?

• Decision

• Input / Output

• Terminator

• Process
