Multiple inheritance causes Diamond problem which happens when:
Class A is parent of class B and C
Now when class D will be inherited from both Class B and C it will have all the members of class A and B which if same will confuse the compiler to import which one?
C++ solves it by using virtual keyword with them and thus telling the compiler which one to inherit.
Java has introduced the interface concept rather then allowing multiple inheritance.
D) Web content developer
Explanation:
A content developer writes a well-researched content for websites, publications, and television. They also write sales copy and other marketing material for online and offline marketing. They develop text, graphics, audios, and videos.
Skills that help web content developer:
- Reading news every day
- Write regularly
- Study end audience
- Develop original and unique content
- Research; reading other people's content as well
- Provide solutions through your content
Besides these, a web content writer must possess technical skills like front-end web development. They must know basic HTML formatting and search engine optimization.
You have to ask you teacher to show you which ones you got wrong and the answers to them.
Answer:
- import java.util.Arrays;
- import java.util.Scanner;
-
- public class Main {
- public static void main(String[] args) {
- Scanner input = new Scanner(System.in);
- double distances [] = new double[7];
-
- for(int i=0; i < distances.length; i++){
- System.out.print("Input running distance for day " + (i+1) + ": ");
- distances[i] = input.nextDouble();
- }
-
- System.out.println(Arrays.toString(distances));
- }
- }
Explanation:
The solution code is written in Java.
Firstly, create a Scanner object to get user input for running distance (Line 6). Next, declare a distances array and set the array size to 7 because we intend to use this array to hold running distance for 7 days per week.
Next, use the for loop that run for 7 times to repeatedly prompt user to input running distance for each day and store each value to the array distances (Line 9 -12).
At last, display the array to console terminal (Line 14).

Explanation:
Hello guys, you might know that C++ is one of the most popular and powerful object-oriented programming languages and if you want to do low-level stuff then it’s the best language to start with.
You will find applications written in C++ on a wide range of fields like embedded programming, server-side application, gaming, and even high-frequency trading applications. Most of the complex software like Operating Systems, Database Management Systems, and Powerful trading systems are written in C++.
While many of us have learned to program by using C and C++, let me honest with you learning C++ is challenging. There are many areas that are tough to grasp like points but you will learn them slowly and that’s where these free C++ courses will help you.
There is no doubt that learning C++ will open several opportunities for you. There is a huge demand for good C++ developers, especially in the area of high-frequency trading where every microsecond matter and power of C++ is absolutely needed.
C++ is the language which provides the best of both world, it allows you to use OOP to manage the complexity of software but at the same time, it also allows you to get close to your machine and access all of your computer’s hardware, which is not easily possible for other object-oriented languages like Java or Python.
That’s the reason C++ is heavily used for writing native device drivers, high-end desktop games and complex artificial intelligence programs where you need high performance.
In this article, I am going to share with you some of the best and free courses to learn C++ online at your own time and place and free of cost. You can use these courses if you are starting with programming or you have some experience in coding but not familiar with C++.
