D Language Online Compiler

Write, Run & Share D language code online using OneCompiler's D language online compiler for free. It's one of the robust, feature-rich online compilers for D language. Getting started with the OneCompiler's D language compiler is simple and pretty fast. The editor shows sample boilerplate code when you choose language as D and start coding.

About D language

D language is a general purpose object oriented programming language similar to C in syntax created by Walter Bright and released in 2001. Dlang is more powerful than C++ as it has gained good features from C++ and also has additional features added.

More productive
Modeling code according to your requirement.
Very good choice for open source software development.

Syntax help

Variables

Syntax

datatype variable-names;

Loops

1. If-Else:

When ever you want to perform a set of operations based on a condition If-Else is used.

if(conditional-expression) {
   //code
}
else {
   //code
}

You can also use if-else for nested Ifs and If-Else-If ladder when multiple conditions are to be performed on a single variable.

2. For:

For loop is used to iterate a set of statements based on a condition.

for(Initialization; Condition; Increment/decrement){  
  //code  
}

3. While:

While is also used to iterate a set of statements based on a condition. Usually while is preferred when number of iterations are not known in advance.

while (condition) {  
// code 
}

4. Do-While:

Do-while is also used to iterate a set of statements based on a condition. It is mostly used when you need to execute the statements atleast once.

do {  
 // code 
} while (condition);

Arrays

Array is a collection of similar data which is stored in continuous memory addresses. Array values can be fetched using index. Index starts from 0 to size-1.

data-type array-name [ array-size ];

Functions

Function is a sub-routine which contains set of statements. Usually functions are written when multiple calls are required to same set of statements which increases re-usuability and modularity.

Syntax

return_type function_name(parameters) {  
  //code
}

How to call a Function
