What is an algorithm?

• A collection of data points without a process.

• A random guess without any steps.

• An algorithm is a step-by-step procedure for solving a problem.

• A recipe for cooking a meal.

Why are algorithms important in programming?

• Algorithms are only useful for sorting data.

• Algorithms are just a form of documentation.

• Algorithms are irrelevant in modern programming languages.

• Algorithms are important because they define efficient problem-solving methods in programming.

Write pseudocode for a program that adds two numbers.

• 1. Start 2. Declare variables a, b 3. Input a 4. Input b 5. Output a - b

• 1. Start 2. Declare variable total 3. Input total 4. Output total

• 1. Start 2. Declare variables num1, num2, sum 3. Input num1 4. Input num2 5. sum = num1 + num2 6. Output sum 7. End

• 1. Begin 2. Set num1 to 0 3. Set num2 to 0 4. Output num1 and num2

What is a flow chart used for?

• To design websites and applications.

• For writing detailed reports.

• To create spreadsheets and tables.

• A flow chart is used for visualizing processes and workflows.

Draw a simple flow chart for making a sandwich.

• Take bread -> Spread condiments -> Cut sandwich -> Add filling

• Gather ingredients -> Top with bread -> Serve -> Cut sandwich

• A flow chart for making a sandwich includes: Gather ingredients -> Take bread -> Spread condiments -> Add filling -> Top with bread -> Cut sandwich -> Serve.

• Gather ingredients -> Take bread -> Add filling -> Serve

What does sequence mean in programming?

• A sequence is an unordered set of instructions in programming.

• A sequence is an ordered collection of elements or instructions in programming.

• A sequence refers to a single element in programming.

• A sequence is a random collection of elements in programming.

Give an example of a sequence in everyday life.

• Reading a book

• Making a cup of coffee

• Driving a car

• Watching a movie

What is selection in programming?

• Selection is the process of making decisions in programming based on conditions.

• Selection is the method of defining variables in programming.

• Selection refers to the order of execution in programming.

• Selection is the process of storing data in programming.

Explain how an if statement works in pseudocode.

• An if statement checks a condition and executes code based on whether the condition is true or false.

• An if statement requires a loop to function properly.

• An if statement can only check numerical values.

• An if statement always executes the code regardless of the condition.

What is a loop in programming?

• A loop is a control structure that repeats a block of code as long as a specified condition is true.

• A loop is a type of variable used in programming.

• A loop is a function that executes only once.

• A loop is a data structure that stores multiple values.
