3.4 Functions and Procedures

• What are functions and procedures in programming?

  Reusable blocks of code
• What is the primary difference between functions and procedures?

  Functions return a value
• What are the inputs to functions and procedures called?

  Parameters
• What is the purpose of a function in programming?

  Compute and return a value
• What are the inputs to a procedure called?

  Parameters
• Procedures can perform actions without returning a value.


  True
• Procedures do not have a return value.


  True
• Functions and procedures help modularize code, making it more reusable and maintainable
• The key difference between parameters and arguments is that parameters are the variable names in the function definition, while arguments are the actual values
• When a function is called, the program's flow of execution moves to the beginning of the function's body
• The identifier used to call a function or procedure is its name
• What is the identifier used to call a function or procedure?

  Name
• Functions use the `return` statement to send back a computed value
• A function definition includes a name, parameters, body, and a return statement
• Functions and procedures are reusable blocks of code that perform a specific task
• The key difference between functions and procedures is that functions compute and return a value, while procedures perform an action but do not return a value.
• Procedures do not return a value, but functions return a value after computation.
• Functions and procedures allow you to modularize your code and make it more reusable and maintainable.
• Functions and procedures make code more modular and reusable.
• The key difference between functions and procedures is that functions compute and return a value.
• Order the steps to define and use a function in programming.

  1️⃣ Define the function with parameters

  2️⃣ Write the function's logic

  3️⃣ Return a value if necessary

  4️⃣ Call the function with arguments
• What are parameters in a function or procedure?

  Named inputs to a function
• Which statement is used in functions to return a computed value?

  return
• What is the primary output of a procedure?

  No return value
• Procedures do not return a value
• Both functions and procedures can accept parameters
• Parameters are the variable names used in the function definition, while arguments are the actual values passed when the function is called.

  True
• Order the steps of function execution.

  1️⃣ Program's flow moves to function body

  2️⃣ Function executes statements

  3️⃣ Function completes

  4️⃣ Control returns to caller
• Match the concept with its purpose.

  Function ↔️ Compute and return a value

  Procedure ↔️ Perform an action without returning a value
• The purpose of functions and procedures is to modularize code and make it more reusable.

  True
• Procedures can perform actions without returning a value.


  True
• Modularizing code using functions and procedures makes it more maintainable.

  True
• Functions can have parameters as inputs.

  True
• What is the primary output of a procedure?

  No return value
• What type of inputs do functions and procedures use?

  Parameters
• What are parameters in programming?

  Named inputs to functions
• Arguments are the actual values passed to parameters when a function or procedure is called.


  True
• Functions and procedures can both perform actions without returning a value.

  False
• Functions and procedures always require parameters.

  False
• Functions and procedures help modularize code and enhance reusability and maintainability.

  True
