Lab 02: Unit Converter This lab will involve writing a program that allows the user to convert a number between units.
Version 1 Ask the user for the number of feet, and print out the equivalent distance in meters. Hint: 1 ft is 0.3048 m. So we can get the output in meters by multiplying the input distance by 0.3048. Below is some sample input/output.
what is the distance in feet? 12 12 ft is 3.6576 m Version 2 Allow the user to also enter the units. Then depending on the units, convert the distance into meters. The units we'll allow are feet, miles, meters, and kilometers.
1 ft is 0.3048 m 1 mi is 1609.34 m 1 m is 1 m 1 km is 1000 m Below is some sample input/output:
what is the distance? 100 what are the units? mi 100 mi is 160934 m Version 3 Add support for yards, and inches.
1 yard is 0.9144 m 1 inch is 0.0254 m Version 4 - optional Now we'll ask the user for the distance, the starting units, and the units to convert to.
You can think of the values for the conversions as elements in a matrix, where the rows will be the units you're converting from, and the columns will be the units you're converting to. Along the horizontal, the values will be 1 (1 meter is 1 meter, 1 foot is 1 foot, etc).
ft mi m km ft 1 0.3048 mi 1 1609.34 m 1/0.3048 1/1609.34 1 1/1000 km 1000 1 But instead of filling out that matrix, and checking for each pair of units (if from_units == 'mi' and to_units == 'km'), we can just convert any unit to meters, then convert the distance in meters to any other unit.
Furthermore you can convert them from meters by dividing a distance (in meters) by those same values used above. So first convert from the input units to meters, then convert from meters to the output units.
Below is some sample input/output:
what is the distance? 100 what are the input units? ft what are the output units? mi 100 ft is 0.0189394 mi Turning in your lab Make sure you are still on your lab branch with git status. This will also show you a list of files that have been modified. Add any files you want git to keep track of using git add filename. Replace filename with the name of your file. You can also use git add . to add everything within the current folder. Commit your work using git commit -m "Your commit message". Make sure your commit message is descriptive and describes what has been changed during this commit. Finally we can run the command git push to send our files up to Github. This may throw an error, but worry not, there will be a suggested command to run, simply copy and paste that command and you should be good to go. Don't forget to visit Github and create a pull request to submit your work for review.
