Basic C++

Today you will learn Basic C++ in 5 minutes.

A Mac with terminal, or on any computer go to https://www.codechef.com/ide on any computer. And your imagination

The first thing you will need to do is make a folder on your desktop, call it anything you want, this is where your c++ projects will go.

Now, you will need to open terminal and type in this, cd ~/Desktop/[Name of the folder] pwd

Congrats you are now in your folder on your desktop. now type in nano test1.cpp,

this will create a file named test1.cpp and bring you to the editing software for editing test1.cpp

now that you have your nano up in terminal, and for those of you not on a mac, in codechef.com/ide. You have to insert a heading, in codechef, they already put in for you, but it is good to know and also nano does not start with it.

This is what you should put in,

#include <iostream>

using namespace std;

int main()

{

return 0;

}

, this is what will make your code run.

Now that we have our starting code, lets start the real program.

#include <iostream>
using namespace std;

int main()

{

//everything in the brackets is code, but when you put two slashes the code ignores that line insert the codebelowthis

cout << " Hello World" << endl;

return 0

}

For those of you in codechef, press the run button in the bottom right. And the output should be Hello World. But for those of you in nano, type in the following:

do control o,

press enter,

do control x,

type in in the regular terminal not nano, type in make test1,

than type in ./test1

it should than run
