Hello, World Program is a basic Simple First program or application. To learn any new language, You have to learn how to write the first program
It just displays the hello world string to the console.
This post shows how to write a hello world application in Nim Programming language.
Nim Hello World example program
Following are steps to create a Hello World program in Nim programming language
- First, Open any source code editor
- Create a file called
- Add the following code
## Hello World Sample First Program echo('Hello World First Program'); }

The comments are ignored by the compiler and provide a useful message about the line or block of a code.
# Hello World Sample First Program
It contains the
echo: It is used to print the string or a message to the console. It is a standalone IO function.
The valid echo statement is
echo "hello world";
The below echo statement gives compilation error /usercode/in.nim(1, 8) Error: missing closing ’ for character literal

How to Compile and run Nim program
We can compile and run the program in many ways in Nim programming.
In this, Let’s see how to compile and run the program using the terminal.
nim command is available on command with installation,
Open terminal command line.
Go to the directory or folder where the program exists.
run the below command(nim c HelloWorld.nim)
A:\work\nim>nim c HelloWorld.nim
argument c is an alias for compile option. This output HelloWorld binary file in the current directory.
Run Nim program with below command
A:\work\nim>HelloWorld ``` Output ```markup Hello World First Program ``` You can compile and run the Nim program with a single command ```markup nim c -r --verbosity:0 HelloWorld.nim ``` c: is an alias for compile option -r: is an --run option --verbosity:0 It restricts and displays only required message - online Nim Playground online browser - open [Nim Playground](https://play.nim-lang.org/) in the browser - Type the HelloWorld code or copy it - Click on the Run button (Ctrl + Enter) on the opened pad. - you will see the `Hello World First Program` message in the Console window. - Source Code Editor or IDE - you can open any editor of your choice such as `VSCode` - Install Extension [Nim](https://marketplace.visualstudio.com/items?itemName=kosz78.nim) - Run inbuilt compiler support or open terminal and run as per command line
