Expert Solution & Answer
Chapter 6, Problem 1D
Explanation of Solution
The two motivations for defining functions in your programs are:
- Reusability
- Abstraction
The first motivation is reusability:
- Once defined, a function can be used over and over and over again.
- User can save your work by invoking the same function many times in the
program . - Another aspect of reusability is that a single function can be used in several different and separate programs.
- When a user needs to write a new program, user can go back to your old programs, find the functions he/she needs, and reuse those functions in his/her new program.
- User can also reuse functions that somebody else has written...

Explain the difference(s) between calling a function by value and calling a function by reference, as well as when each should be used. What are the most significant distinctions between the two approaches of implementation?
Local declarations are those that are kept in the memory of the computer; but, how exactly are they kept in memory? If reaching one's objective can be done without making use of local declarations, then doing so is a waste of time. Why bother using value parameters when you can just use references as your arguments in any function? How crucial are value parameters when it comes to the processing of programmed data?
How are local declarations stored in computer memory? Are there any reasons to avoid using local declarations if it is possible to achieve the same result without them? If reference parameters can be used in any function, why use value parameters at all? How are value parameters useful in processing data in a program?

I meet three questions, and one is asking to write a function header for a function named distance; the second question is to write the prototype for a function named distance, and the third question is to write a function call for a function named distance. I am wondering how to write different functions for these three questions? What are the differences between them?

- Write these codes in c language please. Thank you in advance. 1. Add two more statements to main() to test inputs 3 and -1. Use print statements similar to the existing one (don't use assert). 2. Using the CelsiusToKelvin function as a guide, create a new function, changing the name to KelvinToCelsius, and modifying the function accordingly. 3. Write a function SwapArrayEnds() that swaps the first and last elements of the function's array parameter.
