Algorithms and Pseudo Code

What is pseudo code?

• A programming language
• A flow diagram
• A mix of English language and programming code
• A high-level programming code

What is the purpose of a flow diagram?

• To represent a sequence of steps in an algorithm
• To input and output data
• To calculate complex equations
• To define variables

What is the difference between pseudo code and a programming language?

• Pseudo code is more generic and can be applied to any programming language
• Pseudo code follows a specific syntax for a given programming language
• Pseudo code is used for simple algorithms, while programming languages are used for complex programs
• Pseudo code is used for visual representation, while programming languages are used for execution

What is the purpose of refining an algorithm?

• To make it more efficient
• To make it easier to understand
• To add more steps to the algorithm
• To remove unnecessary steps from the algorithm

What symbol represents the end of a process in a flow diagram?

• Terminal symbol
• Process symbol

• Terminal symbol
• Process symbol
• Decision symbol
• Input/output symbol

What symbol represents input/output in a flow diagram?

• Terminal symbol
• Process symbol
• Decision symbol
• Input/output symbol

What symbol represents a call to a subroutine in a flow diagram?

• Terminal symbol
• Process symbol

• Subroutine symbol

What is the purpose of casting a variable?

• To convert a number to a string
• To convert a string to a number
• To convert a string to uppercase
• To convert a string to lowercase

What is the purpose of a while loop?

• To execute a block of code a specific number of times
• To execute a block of code as long as a condition is true
• To execute a block of code at least once
• To execute a block of code based on a switch statement
