Expert Solution & Answer
Chapter 10.4, Problem 2CP
Explanation of Solution
Encapsulation:
- • It combines the data and code into a single object.
- • It helps in restricting access to the methods.
- • This helps in preventing the data from being modified due to accident.
- • The object’s variable is not directly accessible.
- • Underscore helps in preventing the data from being accessed directly.
The encapsulation rules in Python can be summarized as follows:
| Public method | It is accessible from anywhere. |
| Public variables | It can be accessed from anywhere. |
| Private method | It can be accessed only in their own class |
| Private method | It is accessible only in their class or method. |
- • It protects the data from tampering. By declaring the data field as private, direct modifications of properties are prevented.
- • It makes the class easy to maintain and reduces the errors...

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;
}

- 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.
