How to setup gcc on your PC (For Windows)

Hello there, in this article we will be discussing about setting up our system for c/c++ development by using tools like VS code, gcc compiler etc…

Step 1

Downloading required applications

We will start by first downloading the files that we need from the internet so make sure you are connected to the internet and then click on the following links:-

Mingw w64 compiler

That's it now download both these files and install it simply by using their wizards/installers and it will be very easy too.

After you have succesfully installed both of the applications move to Step 2.

Step 2

Setting up your environment variables

For setting up the environment variable go to

1. Search "Advanced settings" in search bar

2. Open the “environment variables” window, click on the PATH variable and click on “Edit”

3. Click on the “New” button and add the 2 following directories to your PATH

If you have not changed anything manually then add this path here

C:\MinGW\bin

We are all done setting up, and if you followed it correctly move on to STEP 3 to confirm.

Step 3

Checking the installation of gcc on our system

Fire up a terminal by typing "cmd" in your search bar and a window terminal should open and now just type

gcc

and if installation is correct, you should get something like this on your terminal

gcc
gcc: error: unrecognized command line option ‘--v’; did you mean ‘--d’?
gcc: fatal error: no input files
compilation terminated.

with this we have succesfully set up our gcc compiler on our system and we are ready to tun C/C++ program on our PC.

If you face any problems following this article, feel free to ask me in the comments.

Making your first express js server (with explanation)

code-withAshish — Wed, 14 Apr 2021 02:10:51 +0000

express js is a very popular framework built on node js itself and it provides an array of feature and is powerful to the extent that many major tech companies use it in their productions too so with all that in mind let's begin our first step in this express js series !!!

Step 1

Setting up Editor

First of all we will open any code editor, personally i use Vs Code you may use any available like Atom Sublime Text etc...

Step 2

Installing required packages using npm

I am assuming that you have downloaded and installed node js if not just click here and download it and set it up (it's very easy) then open up your terminal in the same directory you are working in and do the following

npm init -y

npm comes with node js so don't worry, you don't have to install it seperately

and after it you should see a file called package.json created by it which looks like this

and after getting this done we again open our terminal and then install express js using npm by using following command

npm install express

It should look like this if succesfully done and if any problem occurs try running it as sudo or for windows as an administrator and make sure you have an internet connection to download the package

Step 3

Writing the script for express js

Now simply make a file with .js extension (because we are working with javascript obviously) with any name , I am naming it server.js

Now copy this code in your file i will be explaining it below so don't worry :)


const express = require("express");

const app = express();

app.get("/", (req, res) => {
  res.send("Hello world");
});

app.listen(3000, () => {
  console.log("Server is Running on Port 3000");
});

Explanation

In the first line const express = require("express") we have included the package in our file it is similar to import in python if you are from python background.
Then we have initialized a variable called app in which we have stored all the functions of express const app = express() and now we will call app instead of writing express everytime just for ease you may use any other name for it.
Now we have used a function get which uses HTTPS GET method and a callback function which handles request and gives responses

app.get("/", (req , res) =>{
res.send("Hello world");
});

"/" this means we are at home page of our webpage and if any get request is there we will send a response by using res.send() i have passed hello world in it which will show a html page there, we can also pass whole html files also( in detail in my next post).

In the last line we have used the function app.listen() which listens for a specific port that we pass there and a callback functions which logs that on which port server is running in our case it's Port 3000 ( you may use any available port on your machine).

Step 4

Finalizing our script and running it

After all this done just run our code by using either code runner extension of vs code or just go to terminal and type

node server.js

and you should see somethig like this in your terminal if everything is fine

and now to see our work just open any browser preferably Chrome latest version and in the search bar just write localhost:3000 you will write the same port number as in your code ( as i used port 3000)
and you should see

Congratulations you just created your first web server in express js!!!!

That's it for now my lovely people stay tuned and happy coding ;)

Feel free to message me if you find any errors in my article there is always scope of error and correction too 😊.
