• Demonstrate use of Linux sufficient for quizzes/exams
• Install Linux on their own computer

You can find my video here:

Hope it helps!

Here is the link to my code:

Here’s the video:

I have successfully installed Linux (Ubuntu) on my own computer:

So I have to go to Plan B, I install Linux in my computer, specifically in my USB.

Here is a video of how do I do it, it was also mastery 6 for Ken’s Course

This two concepts are input and output, and it’s what we are going to talk about in this post.

First, their definition:

Output:

Any information that has been processed by and sent out from a computer or similar device is considered output.

Input:

Any information or data that is sent to a computer for processing is considered input. Input or user input is most often sent to the computer using an input device such as a keyboard or mouse.

Header Files:

To do input and output, you will need to load the iostream header file.

Like this:

#include <iostream>  // I/O

#include <fstream>   // file I/O

#include <iomanip>   // format manipulation

#include <string>

Which means that you’re confirming that your program will have the ability to receive and send information and manipulate it as you tell it to do it.

Streams:

There only exist 3 streams, which are:

Cout (terminal output)

Cin (Terminal input)

Cerr (error output) Mosly used for error messages.

Here are some code examples where you can see Cout and Cin:

#include <iostream>
using namespace std;

int main ()
{
  int v1, v2;
  int sum =0;

  cout<< "Please introduce the lower bound of the range:  ";
  cin>> v1;
  cout<< "Please introduce the higher bound of the range:  ";
  cin>> v2;

  int number =v1;
  while (number<=v2){
    sum= sum+number;
    number++;

  }
  cout<< "The inclusive sum is:  "<<sum<<endl;
  return 0;


}

I really hope this post can help to solve your doubts about Input/Output in C++, if you want to know more abot this I will let you the link of a really good page!

Once again, feel free to ask anything and I will be happy to answer.

Have a nice day!
