The biggest mistake beginners do while started learning to program is using fancy IDEs (Integrated Development Environment). You should use the terminal at least to know how a specific language code is being executed and what's going on behind the scenes. So in this blog, I am going to tell you how to execute source code for a few languages.

###Requirements
1. Using notepad create the source code file for all the languages mentioned in this blog.
2. Make sure you have respected compilers installed on your computer and add to path in environment variables in order use that compiler from anywhere.

##Let's get started...
Open your terminal or command prompt, change the current directory to the location where you created the source code file.

For example: If all of my source code files are in the Programming folder in Desktop.
```
c:\> cd Desktop\Programming
```
Output: `c:\Desktop\Programming>`


##1. C
Type this command in the prompt. Replace hello with your file name. (Hoping you have gcc compiler installed)
```
c:\Desktop\Programming> gcc -o hello hello.c
```
The above command will create an executable file with the extension ".exe". Now type the file name to execute the program.
```
c:\Desktop\Programming> hello
```
Output: `Hello world`


##2. C++
C++ has also same procedure. Type this command in the prompt. Replace hello with your file name. (Hoping you have gcc compiler)
```
c:\Desktop\Programming> gcc -o hello hello.cpp
```
The above command will create an executable file with the extension ".exe". Now type the file name to execute the program.
```
c:\Desktop\Programming> hello
```
Output: `Hello world`


##3. Java
To compile, run this command.
```
c:\Desktop\Programming> javac hello.java
```
After that `hello.class` file will be generated, to run the code type `java <filename>`
```
c:\Desktop\Programming> java hello
```
Output: `Hello World`


##4. C# #
Compile with this command
```
c:\Desktop\Programming> csc hello.cs
```
This will generate a executable file `hello.exe`. You can simple double click it to open or type file name.
```
c:\Desktop\Programming> hello
```
Output: `Hello World`


##5. JavaScript
JavaScript is browser side language, you can console in developer tools of your browser or use [NodeJs](https://nodejs.org).
NodeJs is JavaScript run time, so you can execute JavaScript files using NodeJs. Here's how-

_Note: Make sure you have [NodeJs](https://nodejs.org/en/download/) installed on your computer._

Open terminal and simply type this command.
```
c:\Desktop\Programming> node hello.js
```
Output: `Hello World`


##6. Go
```
go run hello.go
```
Output: `Hello World`

##7. R
You can use `Rscript` to run `R` programs.
```
c:\Desktop\Programming> Rscript hello.R
```
Output: `Hello World`


##8. Swift
```
c:\Desktop\Programming> swift hello.swift
```
Output: `Hello World`


##9. Ruby
```
c:\Desktop\Programming> ruby hello.rb
```
Output: `Hello World`


##10. PHP
```
c:\Desktop\Programming> php hello.php
```
Output: `Hello World`
