What is the primary goal of thinking ahead in programming?

• To write code as quickly as possible

• To ensure the program looks visually appealing

• To anticipate issues and create a reliable program

• To avoid using variables

Why is identifying inputs and outputs important when designing an algorithm?

• It makes the program easier to read

• It ensures the program processes valid data and produces correct results

• It helps the program run faster

• It allows the programmer to use fewer lines of code

What is an input in an algorithm?

• The final result of the program

• The information processed by the program

• The function that runs the program

• The speed at which the program executes

What is an IPO table used for?

• To display program errors

• To structure Inputs, Processes, and Outputs

• To track how much memory a program uses

• To list all variables in a program

Why should preconditions be defined before running a program?

• To ensure the program operates as expected

• To increase the speed of execution

• To make the program look more professional

• To allow the use of more complex functions

What is a precondition in programming?

• A condition that must be met before the program runs

• A condition that appears after the program executes

• A loop that runs continuously

• A function that defines a variable

What is an example of a precondition?

• A loop that repeats until a condition is met

• A program requiring input to be a positive integer

• A function printing an output to the screen

• A user pressing a button to start the program

How do preconditions help prevent errors in a program?

• They ensure correct assumptions about inputs before execution

• They reduce the amount of code needed

• They remove the need for user input

• They increase the complexity of a program

What is caching?

• Storing frequently used data to improve performance

• Deleting unused variables from memory

• Running a program multiple times to test efficiency

• Storing user passwords for security

Why is caching beneficial?

• It allows a program to generate new data constantly

• It speeds up data access by reducing the need for recalculations

• It increases the size of the program for better performance

• It ensures that all program data is always up to date
