  1. Update(s) • 2nd month of coding! • Exam1 – mostly good. Great improvements from the practice exam to the exam itself! • Exam2 (week of March 4th) will be the same delivery mode: practice (EC) + exam. Library functions + loops + arrays (part1) • Material is building on • input, fprintf(), if and switch • If you still have issues with the if, please come daily in my office to do/check your work. Print your code and bring it to the lecture, I’ll quickly go over it. • Reminder: do not work together/collaborate on your work. Even as things get a bit harder. Review the cheating policy in the syllabus. • STAY POSITIVE!

  2. Lab08-tiles Rounding Random

  3. New library functions seen • These functions can be used together (as often is the case) K = rand*8+2  2<float<10 K = ceil(rand*8+2)  3 4 5 6 7 8 9 10 K = floor(rand*8+2)  2 3 4 5 6 7 8 9 K = round(rand*6)  0 1 2 3 4 5 6 CAUTION: K = rand(2,5) does NOT generate a number between 2 & 5.

  4. Today’s lab - background • Retiling a floor! What do you need?

  5. 1st ingredient: the tiles They come in many different sizes, for example: 30 by 30 cm(13 by cartons) 45 by 45 cm(8 by cartons)

  6. 2nd ingredient: the mortar • “The glue for underneath” • Spread using a notched-trowel • There are again different size of trowel, for example: • 6mm • 12mm • Depending on the size chosen, 1 bag won’t last as long.

  7. 3rd ingredient: the grout • The joints between each tile has to be filled with grout. • Depending on the joint width, the number of bags needed is different!

  8. Dimensioning the floor • Snap a chalk line delimiting squares of 9 tiles Grout joint • Advantages? • Cross check • Allows multiple people to work in different rooms!

  9. Your job today… • Develop a program so the user can reuse it to calculate: • The number of tiles needed • The number of cartons needed • The number of bags of mortar needed • The number of bags of grout needed • None of these should be decimals!! • To help the user decide… • Let the program offer the option of randomly choosing the tile size and/or the trowel size.
