2. Structure Chart/Hierarchy Chart
Structure Chart shows :
the functional flow through your program.
how you are going to break your program into logical steps, each step will be a separate module.
the interaction between all the parts(modules) of your program.

3. Flooring cost Get UserInfo Calculate Cost Print Report Calc Linoleum
Calc Carpeting
Calc Kitchen
Calc Bathroom
Calc Bedroom
Calc Living Areas
Structure chart for calculating square footage.

4. Pseudo code Precise algorithmic description of program logic
Its purpose is to describe, in precise algorithm detail, what the program being design is to do.
Requires the defining the steps to accomplish the task in sufficient detail so that they can be converted into a computer program.

5. Pseudocode for Calculate Bathrooms
Algorithm Calculate Cost
1.0 prompt user and read linoleum price
2.0 prompt user and read number of bathrooms
3.0 set total bath area and baths processed to zero
4.0 while (bath processed < number of bathrooms)
4.1 prompt user and read bath length and width
4.2 total bath area = total bath area + bath length * bath width
4.3 add 1 to bath processed
5.0 end while
6.0 bath cost = total bath area * linoleum price
7.0 return bath cost
End Algorithm calculate Bathrooms

6. Flowchart

11. Decision Structure If student’s grade is greater than or equal to 60
Pseudocode
If student’s grade is greater than or equal to 60
Print “Passed”
Else
Print “Failed”

12. Repetition Structure While product is less than or equal to 1000
Pseudocode
While product is less than or equal to 1000
Multiply product by two
