In C++ you are required to create a class called Circle. The class must have a data field called radius that represents the radius of the circle. The class must have the following functions:
(1) Two constructors: one without parameters and another one with one parameter. Each of the two constructors must initialize the radius (choose your own values).
(2) Set and get functions for the radius data field. The purpose of these functions is to allow indirect access to the radius data field
(3) A function that calculates the area of the circle
(4) A function that prints the area of the circle
Test your code as follows:
(1) Create two Circle objects: one is initialized by the first constructor, and the other is initialized by the second constructor.
(2) Calculate the areas of the two circles and displays them on the screen
(3) Use the set functions to change the radius values for the two circles. Then, use get functions to display the new values in your main program
Answers
Here's an example of a C++ class called Circle that meets the given requirements:
```cpp
#include <iostream>
class Circle {
private:
double radius;
public:
// Constructors
Circle() {
radius = 0.0; // Default value for radius
}
Circle(double r) {
radius = r;
}
// Set function for radius
void setRadius(double r) {
radius = r;
}
// Get function for radius
double getRadius() {
return radius;
}
// Calculate area of the circle
double calculateArea() {
return 3.14159 * radius * radius;
}
// Print the area of the circle
void printArea() {
std::cout << "Area: " << calculateArea() << std::endl;
}
};
int main() {
// Create two Circle objects
Circle circle1; // Initialized by first constructor
Circle circle2(5.0); // Initialized by second constructor with radius 5.0
// Calculate and display the areas of the two circles
std::cout << "Circle 1 ";
circle1.printArea();
std::cout << "Circle 2 ";
circle2.printArea();
// Change the radius values using set functions
circle1.setRadius(2.0);
circle2.setRadius(7.0);
// Display the new radius values using get functions
std::cout << "Circle 1 New Radius: " << circle1.getRadius() << std::endl;
std::cout << "Circle 2 New Radius: " << circle2.getRadius() << std::endl;
return 0;
}
```
Explanation:
- The `Circle` class has a private data field called `radius` to represent the radius of the circle.
- It includes two constructors: one without parameters (default constructor) and another with one parameter (parameterized constructor).
- The class provides set and get functions for the `radius` data field to allow indirect access to it.
- The `calculateArea` function calculates the area of the circle using the formula πr².
- The `printArea` function prints the calculated area of the circle.
- In the `main` function, two `Circle` objects are created: `circle1` initialized by the default constructor, and `circle2` initialized by the parameterized constructor with a radius of 5.0.
- The areas of the two circles are calculated and displayed using the `printArea` function.
- The set functions are used to change the radius values of both circles.
- The get functions are used to retrieve and display the new radius values.
When you run the program, it will output the areas of the initial circles and then display the new radius values.

categorization and clustering of documents during text mining differ only in the preselection of categories.
Answers
The statement "categorization and clustering of documents during text mining differ only in the preselection of categories" suggests that the main difference between categorization and clustering lies in how the categories are determined. Let's break it down step by step:
Categorization involves assigning documents to predefined categories or classes based on specific criteria. In this approach, the categories are established beforehand, typically by experts or domain knowledge. The goal is to classify documents into distinct categories for easier organization and retrieval.
In summary, categorization relies on predefined categories determined prior to the analysis, while clustering identifies similarities and groups documents based on those similarities without predefining the categories.

print(("# " * i).rstrip())
Explanation:
You need to print one hashtag, then 2, then 3, and so on. We can use Python's string multiplication to get each line quicker.
String multiplication is an easy way to repeat the same string a certain number of times. It's done by multiplying the string to a number.
For example,
"hello" * 6
>> "hellohellohellohellohellohello"
If we multiply the string "#" by any number, we would get a number of hashtags side by side, without any space. To easily avoid this, we can multiply "# " instead to automatically put a space to the right of each hashtag.
We can use a for loop that goes through range(1, 6) to print out 5 rows.
for i in range(1, 6):
Then, we can print the string "# " multiplied by i.
print("# " * i)
However, this will also put a space at the end of the string, which we do not want to print. Hence, we can use the .rstrip() method to strip the string of any spaces on the right. We will first put the whole string in parentheses, then invoke rstrip on it.
print(("# " * i).rstrip())
Let's put both lines together.
for i in range(1, 6):
print(("# " * i).rstrip())
