I think the correct answer would be that it facilitates the transport of data. It is a very useful tool in the transport and storage of data. XML, also, uses human language rather than computer language so it can be used easily by new users.
Answer:
sidebar
Explanation:
The part of the webpage that is being described in this question is known as a sidebar. These are the far left/right sides of the webpage and are usually used for networking feeds, ads, related information, major points of the main page, biographical info, as well as persuasive information.

The telecommunications device that is widely used in industries that require closed communication are walkie-talkies. Correct answer: D
Walkie-talkies are hand-held, portable, two-way radio transceivers which enable secure communication between the two points, without being part of a network.
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:
The most straight forward way to do it: in general string are zero index based array of characters, so you need to get the length of the string, subtract one and that will be the last character, some expressions in concrete languages would be:
In Python:
name = "blair"
name[len(name) - 1]
In JavaScript:
name = "blair"
name[name.length - 1]
In C++:
#include <string>
string name = "blair";
name[name.length() - 1];
