All rights reserved 1-11 Programming Policy Working With Others These are to be individual efforts, meaning that no code sharing or discussion of problem solutions with anyone except your instructor. You may not incorporate code written by others, such as can be found on the Internet or any of the numerous CS books. During a lab session, you are not Allowed to let another student to copy your work or to copy that of another student. Other Policies Programming assignments may be weighted differently. Documentation is required. You will be given credit only for code that works. This means that you should code and test functions as you write them, not code the whole thing and then try to get it to work, you may get partial grade for non working code if it is logically correct. Submitted projects must run on NETBEANS. programming1- Syllabus

This chapter will cover the following topics: Problem Solving Concepts for the Computer Pre-Programming Phase Programming Or Implementation Phase

14
What Problem Can Be Solved By Computer When the solution can be produced by a set of step-by-step procedures or actions. This step-by-step action is called an algorithm. The algorithm will process some inputs and produced output. Solving problem by computer undergo two phases: Phase 1: Organizing the problem or pre-programming phase. Phase 2: Programming phase.

15
PRE-PROGRAMMING PHASE This phase requires five steps: 1. Analyzing the problem - PAC 2. Developing the Hierarchy Input Process Output (HIPO) chart or Interactivity Chart (IC). 3. Developing the Input-Process-Output (IPO) Chart. 4. Drawing the Program flowcharts. 5. Writing the algorithms.

16
PRE-PROGRAMMING PHASE 1. Analyzing The Problem Understand and analyze the problem to determine whether it can be solved by a computer. Analyze the requirements of the problem. Identify the following: Data requirement. Processing requirement or procedures that will be needed to solve the problem. The output.

17
PRE-PROGRAMMING PHASE All These requirements can be presented in a Problem Analysis Chart (PAC) DataProcessingOutput given in the problem or provided by the user List of processing required or procedures. Output requirement.

18
PRE-PROGRAMMING PHASE Example: Payroll Problem Calculate the salary of an employee who works by hourly basis. The formula to be used is Salary = Hour works * Pay rate DataProcessingOutput Hours work, Pay rate Salary = Hours work * payrateSalary

19
Problem 1 Write a Problem Analysis Chart (PAC) to convert the distance in miles to kilometers where 1.609 kilometers per mile. DataProcessingOutput Distance in miles Kilometers = 1.609 x miles Distance in kilometers

20
Problem 2 Write a Problem Analysis Chart (PAC) to find an area of a circle where area = pi * radius * radius DataProcessingOutput radiusarea = 3.14 x radius x radiusarea

21
Problem 3 Write a Problem Analysis Chart (PAC) to compute and display the temperature inside the earth in Celsius and Fahrenheit. The relevant formulas are Celsius = 10 x (depth) + 20 Fahrenheit = 1.8 x (Celsius) + 32 DataProcessingOutput depthcelsius = 10 x (depth) + 20 fahrenheit = 1.8 x (celsius) + 32 Display celsius, Display fahrenheit

22
Problem 4 Write a problem analysis chart (PAC) that asks a user to enter the distance of a trip in miles, the miles per gallon estimate for the users car, and the average cost of a gallon of gas. Calculate and display the number of gallons of gas needed and the estimated cost of the trip.

23
DataProcessingOutput distance, miles per gallon, cost per gallon gas needed = distance / miles per gallon. estimated cost = cost per gallon x gas needed Display gas needed Display estimated cost

24
Extra Problem Write a problem analysis chart (PAC) that asks a user to enter a unit price and quantity of the product sold. Calculate and display the total sale

25
PRE-PROGRAMMING PHASE Developing the Hierarchy Input Process Output (HIPO) or Interactivity Chart (IC) The problem is normally big and complex. Thus, requires big program. Thus, the processing can be divided into subtasks called modules. Each module accomplishes one function. These modules are connected to each other to show the interaction of processing between the modules.

26
PRE-PROGRAMMING PHASE Main/control module controls the flow all other modules. The IC is developed using top-down-method: top to down left to right order (also refer to order of processing). Modules are numbered, marked for duplication, repetition or decision.

27
PRE-PROGRAMMING PHASE The interaction will form a hierarchy, called Hierarchy Input Process Output Chart (HIPO) or Interactivity Chart (IC). Programming which use this approach (problem is divided into subtasks) is called Structured Programming. Main Module Module 3Module 2 Module 1 Module 5Module 4Module 6

28
PRE-PROGRAMMING PHASE PAYROLL 0000 READ 1000 PRINT 3000 CALCULATE 2000

29
PRE-PROGRAMMING PHASE Example 2.2: Extended Payroll Problem You are required to write a program to calculate both the gross pay and the net pay of every employee of your company. To determine the gross pay, you have to multiply the accumulated total hours worked by the employee, by the appropriate pay rate. The program should print the cheque that tells the total net pay. The net pay is calculated by subtracting the gross pay with any deductions that may be incurred by the employee.

30
PRE-PROGRAMMING PHASE Accumulate Hourly Worked 1100 Payroll 0000 Calculate Gross Pay 1000 Determine Pay rate 1200 Write Cheque 3000 Calculate Net Pay 2000 Calculate Deductions 2100

31
Problem 1 Write a Hierarchy Input Process Output (HIPO) to convert the distance in miles to kilometers where 1.609 kilometers per mile. Convert the distance 0000 Distance in miles 1000 Kilometers = 1.609 x miles 2000 Distance in Kilometers 3000

32
Problem 2 Write a Hierarchy Input Process Output (HIPO) to find an area of a circle where area = pi * radius * radius Area 0000 radius 1000 area = 3.14 x radius x radius 2000 Display area 3000

33
Problem 3 Write a Hierarchy Input Process Output (HIPO) to compute and display the temperature inside the earth in Celsius and Fahrenheit. The relevant formulas are Celsius = 10 x (depth) + 20 Fahrenheit = 1.8 x (Celsius) + 32 Temperature 0000 Calculate temperature in celsius 1000 Calculate temperature In fahrenheit 2000 Display Temperature 3000 Get depth 1100

34
Problem 4 Write a Hierarchy Input Process Output (HIPO) that asks a user to enter the distance of a trip in miles, the miles per gallon estimate for the users car, and the average cost of a gallon of gas. Calculate and display the number of gallons of gas needed and the estimated cost of the trip.

35
Estimation Cost 0000 Calculate gas Needed 1000 Calculate estimated Cost 2000 Display gas needed Display estimated Cost 3000 Get total distance in miles 1100 Get miles per gallon 1200 Get average cost per gallon 2100
