Programming Fundamentals

What is a variable in programming?

• A function in programming

• A symbolic name for a value that can change

• A constant that cannot be changed

• A fixed value in programming

Name three common data types used in programming.

• array

• integer, string, boolean

• character

• float

What is the purpose of control structures in programming?

• Control structures in programming are used to dictate the flow of execution within a program.

• Control structures are used for decorative purposes in programming.

• Control structures are designed to confuse programmers.

• Control structures help in organizing code in a visually appealing way.

Explain the difference between if-else and switch-case statements.

• Switch-case statements are more flexible than if-else statements

• Switch-case statements are suitable for complex conditions

• If-else statements can only handle fixed options

• The if-else statement is more flexible and can handle complex conditions, whereas the switch-case statement is more suitable for scenarios with multiple fixed options.

What are functions in programming and why are they useful?

• Functions in programming are blocks of code that can only be used once.

• Functions in programming are not useful as they make code more complex.

• Functions in programming are reusable blocks of code that perform a specific task. They are useful because they help in organizing code, reducing redundancy, improving readability, and promoting code reusability.

• Functions in programming are only used for basic tasks and not for complex operations.

How do you define a function in most programming languages?

• Using the 'def' keyword followed by the function name and body.

• By declaring a variable with the function name and assigning it a block of code.

• Creating a class with the function name as a method.

• Using the 'function' keyword followed by the function name, parameters, and body.

What is the difference between a function and a method?

• A method is a standalone block of code that can be called independently.

• A function is always static, while a method can be static or non-static.

• A function is a standalone block of code that can be called independently, while a method is a function that belongs to a class or object.

• A function is a method that belongs to a class or object.

Explain the concept of parameters and arguments in functions.

• Parameters are only used in built-in functions, while arguments are used in user-defined functions.

• Parameters and arguments are interchangeable terms in function definitions.

• Parameters are values supplied when calling the function, while arguments are defined in the function signature.

• Parameters are defined in the function signature, while arguments are the values supplied when calling the function.

What is the return statement used for in functions?

• To define a new variable

• To stop the execution of the function

• To specify the value that the function should return when called.

• To print a message to the console

How do you call a function in a program?

• By using a magic spell

• By clicking on the screen

• By writing the function name followed by parentheses

• By sending a text message
