Question
Chapter 4.4, Problem 17STE
Program Plan Intro
Description of Function:
Function has two parts that are called “function declaration” and “function definition”.
- The function declaration defines how the function is called.
- The function definition defines how the function computes the value it returns.

- Explain how a function works with a relevant example.arrow_forward. What is the difference between a function argument and a function parameter? Group of answer choices An argument is a variable that is created in a function to hold a value that has been sent to it and a parameter value is the value that a function returns to the calling routine. An argument is a value that is passed into a function and a parameter is variable that the function defines to hold value of the argument. An argument is a value that is passed into a function and a parameter is the value that a function returns to the calling routine. A parameter is a value that is passed into a function and an argument is the value that a function returns to the calling routine.arrow_forwardCan you give one example on each type of functions in Programming?arrow_forward
- 13. What is the difference between a formal parameter and an argument? Group of answer choices A function’s argument is referred to as the formal argument to distinguish it from the value that is passed in during the function call. The parameter is the passed value. They are identical but using different terms. A function’s parameter is used for passing by reference. The argument is used for passing by value. A function’s parameter is referred to as the formal parameter to distinguish it from the value that is passed in during the function call. The argument is the passed value. A function’s parameter is used for passing by value. The argument is used for passing by reference.arrow_forwardStep 2: Self-Explanation Next, it's time to focus on understanding part of the provided code. Examine Lines 72 and 73: Look at the variables being created: cat and an. What do you think these lines of code are doing? Hint: Look back at line 1 of the code. Use Google to investigate what the function on line 1 (randint) does. How does that give you a clue about lines 72 and 73? Explain Their Role in the Program: Now that you've identified what lines 72 and 73 are doing, explain how these variables are used when calling the get_answer() function on line 75. What do you think these variables represent within the context of the program, and how does get_answer() use them to produce output? Step 3: Break It Down Further Now that you understand how random values are generated and used in get_answer(), think about how this relates to the rest of the lab.
