A Sample D Programming Language Program

The D programming Language is an Object oriented programming language. It is designed by Walter Bright, Andrei Alexandrescu and developed by Digital Mars, Andrei Alexandrescu. Though it originated as a re-engineering of C++, D is a distinct language, having redesigned some core C++ features while also taking inspiration from other languages, notably Java, Python, Ruby, C#, and Eiffel. In D programming language usual filename extension is ".d".

Now lets write a sample D programming language program to add two numbers.

NOTE: before running this program make sure that GDC compiler installed on your system. (sudo apt-get install gdc)

// File Name: Addition.d

import std.stdio;
import std.cstream;
import std.conv;

int main()
   int num1, num2, sum;
   char[] line;
   // Readign first number
   writef("Enter 1st Number: ");
   line = din.readLine();
   num1 = std.conv.toInt(line);
   // Reading second number
   writef("Enter 2nd Number: ");
   line = din.readLine();
   num2 = std.conv.toInt(line);
   // Adding
   sum = num1 + num2;
   // Displaying sum
   writefln("The Sum is %d", sum);
   return 0;

To Run: gdc Addition.d
