D Programming – Variables

Hi there, I recently enjoyed learning some programming languages which are new to me. I came across with the D Programming Language. I have already put up an article on the codes on the basic console output in D located here: https://arjunaraneta.wordpress.com/2014/09/27/d-basic-output/

You can think of variables as an address in your memory that contains data that you’ll need and use. The syntax for using variables in python in very straightforward.

Here is a basic example of declaring a variable named x with a value of 10. After declaring and assigning a value, the program will output the value of x.

import std.stdio;

int main(){
int x = 10;
writeln("x = ", x);

  return 0;
}

The output should be:

x = 10

On the next example below, I declared two variables named x and y. I assigned a value for each of the variables. After assigning the values, I created another variable named z assigned the sum of x and y. The program will output the result after the addition.

import std.stdio;

int main(){
	int x = 10, y = 5;
	writeln("x + y = ", x + y);
	
	return 0;
}

The output should be:

x + y = 10

Thank you for your time 🙂

D – Basic Output

In this tutorial, I will be introducing you to a language called D. We will be creating a simple program that outputs “Hello World” on the screen.

First, you should download D here: http://dlang.org/download.html

 

Then, install the software. Installation is very easy because all you need to do is read and follow the directions.

 

After installation, create a new folder in My Documents named tutorials.

While inside the tutorials folder, create a new text document and rename it output.d.

Open the file with your favorite text editor (I love to use Notepad++).

Type the codes same as below:

d1

 

 

Open your command prompt.

Next, change your directory using the cd command.

type dmd then the name of your file

type the name of the exe file that was generated.

our output should be the same as below:

 

d2

 

 

Thank you for reading this post.
