Document Summary

Unit ii: computational thinking and introduction to python. Simple logic building through flowcharting:flowchart symbols, conditional and repetition blocks. Basic structure of a python program, elements of. Python programming language: token, literals, identifiers, keywords, expression, type conversions, numbers, variables, input/output statements, basic data types. Flowchart is a diagrammatic representation of sequence of logical steps of a program. Flowcharts use simple geometric shapes to depict processes and arrows to show relationships and process/data flow. The common symbols used in drawing flowcharts are. Advantages of flowchart: the flowchart is an excellent way of communicating the logic of a program, during program development cycle, the flowchart plays the role of a guide or a blueprint. It is easy and efficient to analyze problem using flowchart. Which makes program development process easier: after successful development of a program, it needs continuous timely maintenance during the course of its operation. The flowchart makes program or system maintenance easier.

I need help solving these questions for my software class:

12. Match each term with its definition

Word list: documentation, evolutionary prototype, GUIs, fourth generation, information gathering prototype, libraries, Lips and Prolog (5GLs), prototype, prototyping approach, short-term solution

Term Definition

	Programming languages often used in information gathering prototype development
	Usually involves only a small team of programmers and one or more users
	Type where the prototype becomes the full working program
	Term used to describe the scale and budget for most prototyping projects
libraries	Collections of reusable code often used to speed up prototype development
Lips and Prolog (5GLs)	Languages often used in the development of prototypes of both kinds
GUIs	Favoured interface for prototype development
information gathering prototype	Prototypes developed to gather information that can be used in another development
documentation	Stores critical information for future maintenance
prototype	A working model that can be evaluated by users

14. Complete the Methods of Implementation table, using the information provided below.

One section of the organisation uses the new program and all other sections continue with the old program until a decision is made to put the new program into place across the whole organisation	One or more tasks of the new program are gradually implemented until the new program takes over all tasks of the old program
The old and the new program work together	The new program immediately replaces the old program

Method	Description	Diagram (draw it yourself)
Direct Cut Over	The new program immediately replaces the old program
Parallel Implementation	The old and the new program work together for a period of time
Phrased Implementation	One or more tasks of the new program are gradually implemented until the new program takes over all tasks of the old program
Pilot Implementation	One section of the organisation uses the new program and all other sections continue with the old program until a decision is made to put the new program into place across the whole organisation

You have been contracted by a popular fitness club to create a Java Program that
will help in the input, calculation, display of calories burnt and pounds lost during a week of
workout for members of the club.
The program will also base on the amount of weight lost update the weight of the user and
calculate and display the users BMI – body mass index using any researched method. See an
example here- http://www.whathealth.com/bmi/formula.html
The club takes part in 5 major types of activities, namely walking, running, swimming, hiking,
and bicycling.
The program is to prompt for the Name of the member, gender, weight in pounds, height and
the time spend on each activity during the week in minutes.
The program will then calculate the calories burnt per activity, the total calorie burnt for the
week and the amount of weight lost during the week.
The amount of weight loss will be used to update the weight that was stored in the array and
calculate the person BMI . http://www.whathealth.com/bmi/formula.html
Activity Calorie Burnt Per pound per minute for
men (women are 1/6 less)
Walking .036
Running .095
Swimming .058
Hiking .058
Bicycling .044
 Calories burned per pound per minute (Bicycling – .044) x (times) your exact weight
(140 pounds) = (equals) total calories burned per minute (6.16 calories burned per
minute) x(times)minutes of activity (30 minutes) = (equals) 184.80 total calories
burned per activity.
 Women burn 1/6 less calories than Men.
 3500 calories = 1 pound of weight loss.
Author: Dexter Chin-Yan
Write a program that would do the following:
 Print a suitable heading and prompt for the required information
 Calculate the necessary required information and store in an Array(s)
o After members names, gender, weight in pounds and time spent in each
activity has been entered (10 Members) The program should calculate the
total calories burnt Total Calorie Burnt for the week and the amount of
weight loss (depending on whether it is a man or a woman.
o Calculate and display BMI and weight status based on the table above.
General Guidelines:
 Make use of appropriate messages to make you program as informative and user
friendly as possible, without being unnecessarily complex.
 Keep user interactions simple and instructions clear
 Use adequate documentation and proper indentation to clarify your program code
where necessary and improve layout
 Pay attention to good structure and use of programming constructs.
Evaluation
 Documentation and layout (spacing, indentation and commenting) 10 marks
 Proper layout of interface for input, output of information 10 marks
 Use of method to calculate, BMI, calories burnt per activity, and weight loss.
20 marks
 Creation and use of arrays to hold and processed information 20 marks
 Working program (Correctness, efficiency, user interaction)
