Question
Chapter 6, Problem 4D
Program Plan Intro
Function:
- Function is a part or block of code.
- These become the important tools to build a complicated program.
- Functions are mostly used to decrease the code duplication.
- These also make the programs easier to maintain and easily understandable.
- Functions are available both in-built and are also defined by programmers.
b)
Explanation of Solution
Output to a function:
- Output of a function is also stored in a variable.
- The value of the output variable is returned or printed inside the specific function...

write a program which consists of a user defined function task
Predefined functions are less efficient than those that are defined by the user.
Functions allow us to group instructions and assign them a label (the name of the function) and refer to this label anywhere in the program where the action implemented by the function is required.
Describe at least 2 different uses of functions in the construction of a program. Reference two problems from the assignments that illustrate these uses.

- Mathematical functions introduced in chapter 4 can be used in the mathematical calculations and simulations of the engineering and scientific problems. In these cases, we formulate the mathematical problem and then use the computer for calculations and simulations. Can a computer code solve the math problem and come up with mathematical formulas, i.e. can a computer program do what a mathematician does?arrow_forwardWhat are three things that need to happen when a subprogram returns to the function that called it?arrow_forwardThe effectiveness of user-defined functions much exceeds that of pre-defined ones.arrow_forward
- The distinction between an argument and a parameter variable in programming pertains to their respective roles and functionalities within a program?arrow_forwardIf a program includes user-defined functions, why is it necessary to provide function prototypes in the program?arrow_forward• You are to work on this activity individually. • You are to create a Python application that applies classes and objects in Python. • Scenario: You are to create a python application that simulates the function of a basic calculator with some additional features. The user will select what function they would like to use in the application, after which they will input the va they would like to use for the computation selected. The program will then compute for the output based on the give function and return the output to the user. The user should then be able to select additional functions and input new until they are satisfied, after which they can exit the application. • The application should first ask for a command from the user when started, the user can do 9 different commands on application: 。 The Calculator Features ▪ Add Two Numbers - Adds two numbers inputted from the user. Subtract Two Numbers - Subtracts two numbers inputted from the user. Multiply Two Numbers -…arrow_forward
- If you have the time, could you elaborate more on the function metrics serve in the software development process? Everything must be described in great depth.arrow_forwardWhen writing programs, what is a recursive functior.? A. A function that calls another function A function that calls itself only once C A function that calls itself or another function that eventually calls the original function A recursive function is any composite function that eventually calls itself only once.arrow_forwardA user-defined functions programme must supply function prototypes.arrow_forward
- Invoking a function that takes many arguments, the order in which parameters are supplied is crucial.arrow_forwardThe semantics of a call to a “simple” subprogram requires the following actions: A. Save the execution status of the current program unit. B. Compute and pass the parameters. C. Pass the return address to the called. D. Transfer control to the called. E. All of the abovearrow_forwardWe have been thinking about computer programs as sequences of instructions where the computer methodically executes one instruction and thenmoves on to the next one. Do programs that contain functions fit thismodel? Explain your answer.arrow_forward
