Unit Conversion
Description:
Write a menu driven program with the following options:
1. Subject 1 (with atleast 5 units)
2. Subject 2 (with atleast 5 units)
3. Subject 3 (with atleast 5 units)
4. Subject 4 (with atleast 5 units)
5. Exit
Note: Go to the website http://www.onlineconversion.com and use the information from
There.
Subject means here length, temperature, etc. and the units are centimeters (cm), meters
(m), Fahrenheit, Centigrade, etc. Select any 5 units from any 4 subjects (Length,
Temperature, Speed, etc.) Found in the website mentioned above. After selecting the
Subject a sub menu needs to be shown with at least 5 units. Make last option as return to
Main menu and the program only exit from the main menu. Convert the values by giving
Options to a user which can be the 2 units and a value to be converted. Make the options
User-friendly and make all possible error checking in order to avoid mistakes. (Add 4
More subjects if you are doing the project in group of 2 students).
Save the output of each run in a file along with the details of when it was run (full date
And time). Give an option to the user for opening a new file (with new name or overwrite
The previous one) or append in a previous file.
Practice modular programming by writing functions whenever possible. Follow the
Convention concerning variable names. Insert comments wherever needed.
Hint: Use mode ‘a’ or ‘a+’ in fopen function instead of ‘w’ to append/accumulate the
Results.
Use different functions for each unit and make efficient use of files.

The comments have not been added to the program because of the time limit.ALthough the entire logic has been maintained in the program.
