Computer Software

• Definition
• Instructions for the computer
• A series of instructions that performs a
  particular task is called a program or software
  program.
• The two major categories of software are system
  software and application software

Computer Software

• What is a computer Program?
• Computer code is a series of written commands or
  instructions
• Code strung together for a coherent and
  complete purpose and able to run on its own on a
  computer is called a program.
• The written-out version of an entire program in
  its original language is called source code

Computer Software Language Types

• There are two types of programs
• Compiled
• COBOL, Visual Basic
• C
• C
• Java
• Interpretative
• VBScript
• JavaScript

Must be compiled Into an .EXE type file Before it
can be executed
Compiled at time of it Execution, such as it Is
done by browsers

that displays the sum of two numbers. // Java
packages import javax.swing.JOptionPane //
program uses JOptionPane public class Addition
// main method begins execution of Java
application public static void main( String
args ) String firstNumber //
first string entered by user String
secondNumber // second string entered by user
int number1 // first number to
add int number2 // second number
to add int sum // sum of
number1 and number2 // read in first
number from user as a string firstNumber
JOptionPane.showInputDialog( "Enter first
integer" ) // read in second number from
user as a string secondNumber
JOptionPane.showInputDialog( "Enter second
integer" ) // convert numbers from type
String to type int number1
Integer.parseInt( firstNumber ) number2
Integer.parseInt( secondNumber ) // add

Computer Software Developing Methodology

• Structured Programming Techniques
• It is a general term referencing to programming
  that produces programs with clean flow, design,
  and a degree of modularity or hierarchical
  structure
• Modularization
• Break-up the the solution into manageable modules
• The benefits of Structured Programming include
• Ease of readability
• Ease of maintenance
• Lower maintenance costs
• Long term use

12
Computer Software Developing Methodology

• The Structure Theorem forms the basic framework
  for structured programming
