This part of the project is the last for the unit conversion program and will combine

everything from the modules to create a program that can convert units of measurement

to$/$from imperial and metric. For this task you$$ll be required to create a text$-$based user

interface that calls the user$-$defined function you created in module $2$ to perform the

required unit conversions.

User Interfaces are important in computer programs; they consist of menus and prompts

that can be interacted with by a user to input information into the program.

User$-$defined functions allow for effective code reuse and is good programming practice

when creating programs that require the same or similar code to be executed many times
