  Tutorial: Programming: Numeric Conversion

Read a number (or numbers) in one system and output the equivalent number (or numbers) in the other system.

Tutorial Details:

Write a program which converts a measurement from one system of units to another. Read a number (or numbers) in one system and output the equivalent number (or numbers) in the other system. Instead of thinking of it as a conversion, it could also be a calculation, eg, to calculate the air pressure from the altitude.

Model program and iterative programming
Start with Kilometers to Miles as an example of how a conversion program might be written.

Iterative programming is the process of writing some of the program, compiling and testing it, then writing more, compiling and testing that, etc. Keep going in this cycle until the program is done. The iterative style generally has a much higher success rate than writing the entire program, then compiling and testing it. You may also have to make greater changes to it, eg to read two values, one for feet and one for inches.
