1 Update(s) 2 nd month of coding! Exam1 – mostly good. Great improvements from the practice exam to the exam itself! Exam2 (week of March 4 th ) 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, Ill 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!

4 Todays lab - background Retiling a floor! What do you need?

5 1 st 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 2 nd 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 wont last as long.

7 3 rd 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 Advantages? -Cross check -Allows multiple people to work in different rooms! Grout joint

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.
