Unit #1-05

Learning Outcome

At the end of this lesson, you will be able to:

• create an application that uses functions

Review

• why do we have functions

  • code modularity and reusability

Lesson

• read "Functions", Chapter 3, Computer Based Problem Solving

  • read up to and including "By Value or By Reference"

Daily Assignment

• read the following problem:

  • A board foot is defined as a piece of wood that is 12 inches wide by 12 inches long by 1 inch thick or 144 inches³.

  • Create a function called BoardFoot, that has 2 parameters, the width and the height.

  • It will then calculate the length, so that the result is exactly 1 board foot and return that value.

  • Your "main()" will from now do all the "input, error checking and output". The logic and process will ALWAYS be in functions from now on.

  • from now on ONLY do the flowchart for the functions, NOT main() any more

Extra

• do the above in a second language
