Description

Files to submit: conversions.c

Time it took Matthew to Complete: 45 mins

• All programs must compile without warnings when using the -Wall and -Werror options

• Submit only the files requested

• • Do NOT submit folders or compressed files such as .zip, .rar, .tar, .targz, etc

• Your program must match the output exactly to receive credit.

• • Make sure that all prompts and output match mine exactly.

• • Easiest way to do this is to copy and paste them

• All input will be valid unless stated otherwise

• Print all real numbers to two decimal places unless otherwise stated

• The examples provided in the prompts do not represent all possible input you can receive.

• All inputs in the examples in the prompt are underlined

• • You don’t have to make anything underlined it is just there to help you differentiate between what you are supposed to print and what is being given to your program

• If you have questions please post them on Piazza

Restrictions

• No global variables are allowed

• Your main function may only declare variables and call other functions.

Assumptions

• Input is NOT guaranteed to be valid

For this program you will be converting temperatures and distances from one unit to another.

Temperatures

From		Fahrenheit		Celsius		Kelvin
Fahrenheit(F)		F		(F – 32) * 5/9		(F-32) * 5/9 + 273.15
Celsius(C)		(C * 9/5) + 32		C		C + 273.15
Kelvin(K)		(K – 273.15) * 9/5 + 32		K – 273.15		K
			Distances
From	Inches		Feet	Yards	Miles
Inches(I)	I		I/12	I/36	I / 63360
Feet(F)	F*12		F	F / 3	F / 5280
Yards(Y)	Y*36		Y * 3	Y	Y / 1760
Miles(M)	M * 63360		M * 5280	M * 1760	M

Requirements:

• Users should be able to enter both upper and lower case letters for their choices

• Any amount of white space should be allowed between a number and its unit

Hints:

• This is a large program that you will want to break down into lots of functions to help manage the complexity

• When doing the conversions you can save yourself a bit of work by always converting your units into a common one and then converting to the desired one.

• • For example when converting temperatures you could always convert the given temperature to Celsius and then from Celsius go to the desired unit

Examples on Next Page.

Examples:

1. T or t for temperature D or d for distance Enter your choice: t

Enter the temperature followed by its suffix (F, C, or K): 0K

Enter the new unit type (F, C, or K): C 0.00K is -273.15C

2. Pick the type of conversion that you would like to do. T or t for temperature

D or d for distance Enter your choice: d

Enter the distance followed by its suffix (I,F,Y,M): 5 y

Enter the new unit type (I,F,Y,M): i 5.00Y is 180.00I

3. Pick the type of conversion that you would like to do. T or t for temperature

D or d for distance Enter your choice: J

Unknown conversion type J chosen. Ending Program.

4. Pick the type of conversion that you would like to do. T or t for temperature

D or d for distance Enter your choice: 10

5. Invalid formatting. Ending program.

6. Pick the type of conversion that you would like to do. T or t for temperature

D or d for distance Enter your choice: t

Enter the temperature followed by its suffix (F, C, or K): 42 G G is not a valid temperature type. Ending program.

7. Pick the type of conversion that you would like to do. T or t for temperature

D or d for distance Enter your choice: t

Enter the temperature followed by its suffix (F, C, or K): 420 Blaze It

8. Invalid formatting. Ending program.
