Answer:
Explanation:
public class Temperature
{
double ftemp;
public int Constructor(double fahrenheit)
{
ftemp = fahrenheit;
return Convert.ToInt32(ftemp);
}
public void setFahrenheit(double fahrenheit)
{
ftemp = fahrenheit;
}
public void getFahrenheit()
{
ftemp = Constructor(ftemp);
}
public void getCelcius()
{
ftemp = (ftemp - 32) * 5 / 9;
}
public void getKelvin()
{
ftemp = (ftemp - 32) * 5 / 9 + 273.15;
}
}
Answer:
boolean recalled;
((modelYear>=1995 && modelYear <=1998) || (modelYear>=2004 && modelYear<=2006)) ? recalled =true : recalled =false;
Explanation:
In the first line of the code we declare the variable of type boolean (values can only be true or false) then using the conditional expression operator (ternary operator) in place of an if statement, We state the conditions of the years that will return true and vice versa
Answer:
- from matplotlib import pyplot as plt
-
- with open("text.txt") as file:
- data = file.readlines()
- category = []
- amount = []
- for row in data:
- values = row.split(" ")
- category.append(values[0])
- amount.append(float(values[1]))
-
- figure = plt.figure()
- ax = figure.add_axes([0,0,1,1])
- ax.axis('equal')
- ax.pie(amount, labels = category, autopct='%1.2f%%')
- plt.show()
Explanation:
Firstly, we need to import matplotlib library (Line 1).
Next, open a file stream and use readlines method to read the data from the text file (Line 4). Presume the data read from the text files are as follows:
Rent 450
Gas 150
Food 500
Clothing 120
Car 600
Create two lists, category and amount (Line 5-6). Use a for loop to traverse through the read data and use split method to break each row of data into two individual items. The first item is added to category list whereas the second item is added to amount list (Line 7 - 10).
Next, create a plot figure and then add the axes (Line 12 - 13). We can use the pie method to generate a pie chart (Line 15) by setting the amount list as first argument and category list as value of labels attributes. The output pie chart can be found in the attachment.
Answer:
b) objects are resuable
Explanation:
In OOP there's code reuse where a method or any other body of code is defined once and called or reused severally.
