Data Structure - Useful Resources

The following resources contain additional information on Data Structures and Algorithms. Please use them to get more in-depth knowledge on this topic.

Discuss Data Structures & Algorithms

Data Structures are the programmatic way of storing data so that data can be used efficiently. Almost every enterprise application uses various types of data structures in one or the other way. This tutorial will give you a great understanding on Data Structures needed to understand the complexity of enterprise level applications and need of algorithms, and data structures.

D Programming - Overview

D programming language is an object oriented multi-paradigm system programming language developed by Walter Bright of Digital Mars. It's development started in 1999 and was first released in 2001. The major version of D(1.0) was released in 2007. Currently, we have D2 version of D.

D - Environment

Try it Option Online

You really do not need to set up your own environment to start learning D programming language. Reason is very simple, we already have set up D Programming environment online, so that you can build and execute all the available examples online at the same time when you are doing your theory work.

D - Basic Syntax

D is quite simple to learn and lets start creating our first D program!

First D Program

Let us write a simple D program. All D files will have extension .d. So put the following source code in a test.d file.

import std.stdio;

D - Variables

A variable is nothing but a name given to a storage area that our programs can manipulate. Each variable in D has a specific type, which determines the size and layout of the variable's memory; the range of values that can be stored within that memory; and the set of operations that can be applied to the variable.

D - Data Types

In the D programming language, data types refer to an extensive system used for declaring variables or functions of different types. The type of a variable determines how much space it occupies in storage and how the bit pattern stored is interpreted.

D - Enums

An enumeration is used for defining named constant values. An enumerated type is declared using the enum keyword.

The enum syntax

The simplest form of an enum definition is the following:

enum enum_name { 
   enumeration list
}

Where,

D - Literals

Constant values that are typed in the program as a part of the source code are called literals.
Literals can be of any of the basic data types and can be divided into Integer Numerals, Floating-Point Numerals, Characters, Strings and Boolean Values.

D - Operators

An operator is a symbol that tells the compiler to perform specific mathematical or logical manipulations. D language is rich in built-in operators and provides the following types of operators:

D - Loops

There may be a situation, when you need to execute a block of code several number of times. In general, statements are executed sequentially: The first statement in a function is executed first, followed by the second, and so on.

D - Decisions

Decision making structures require that the programmer specify one or more conditions to be evaluated or tested by the program, along with a statement or statements to be executed if the condition is determined to be true, and optionally, other statements to be executed if the condition is determined to be false.
