Program Plan Intro
Software:
- Software is a group of instructions and related documentation that informs a computer “what to do or how to perform a task”.
- Software is divided into two following categories.
- System software
- Application software
System software:
- It is used to control and manage the basic computer operations and it is referred as “system software”.
- It includes the following program types:
Operating Systems: - It is used to control the internal operations of the computer’s hardware, managing computer devices and allowing users to perform data manipulations from storage devices, etc.
- Utility Programs:
- It is used to perform a special task that improves the computer’s operation. Programs like data backup, virus scanners and file compression are the examples.
- Software Development Tools:
- Tools that help the programmer to create, test and modify software are referred as Software development tools.
Application Software:
- Application software or applications are referred as productivity programs; because, they allow users to complete their task. Examples: Document creation,
databases , etc. - This software is designed to do a specific task. It might be simple or complex that depends on the application used.

Methods (Ch6) - Review
1. (The MyRoot method) Below is a manual implementation of the Math.sqrt() method in Java.
There are two methods, method #1 which calculates the square root for positive integers, and
method #2, which calculates the square root of positive doubles (also works for integers).
public class SquareRoot {
public static void main(String[] args) {
}
// implement a loop of your choice here
// Method that calculates the square root of integer variables
public static double myRoot(int number) {
double root;
root=number/2;
double root old;
do {
root old root;
root (root_old+number/root_old)/2;
} while (Math.abs(root_old-root)>1.8E-6);
return root;
}
// Method that calculates the square root of double variables
public static double myRoot(double number) {
double root;
root number/2;

- Write a C++ program that will count from 1 to 10 by 1. The default output should be 1, 2, 3, 4, 5, 6 , 7, 8, 9, 10 There should be only a newline after the last number. Each number except the last should be followed by a comma and a space. To make your program more functional, you should parse command line arguments and change behavior based on their values. Argument Parameter Action -f, --first yes, an integer Change place you start counting -l, --last yes, an integer Change place you end counting -s, --skip optional, an integer, 1 if not specified Change the amount you add to the counter each iteration -h, --help none Print a help message including these instructions. -j, --joke none Tell a number based joke.
