Question

Prepare an algorithm that will accept the length and width of a rectangle and calculate and display it's area.

Answer 1

Answer:

You do it by designing a solution in your mind, and then onto paper. You devise the algorithm without the computer or programming language. Your mind has to see the process before you can teach the computer to mimic your mind.

You must be an architect of sorts. When you see or hear about a problem (or opportunity), your mind should immediately start figuring out what kind of data the program will need to produce (ie answers), and where input data will come from, or how the program will get it. You should also start thinking about specific hardware/software combinations.
