What are string literals in D programming?

What are literals?

Literals are values of variables that cannot be changed after definition. They are fixed by programmers during the creation of code.

Types of literals in D

We have five types of literals in D programming:

  1. Integer Numeral
  2. Floating point Numerals
  3. Characters
  4. Strings
  5. Boolean value.

In this shot we would focus on the String literal.

What are string literals?

Strings literals are a sequence of character wrapped in double "" , they are analogous to plain characters, escape sequences, or universal characters.

String literals are also used to break long lines of multiline text. Let’s see an example.

Example

import std.stdio;
int main(string[] args) {
   writeln(" Greetings From a  
   Fellow Developer
     ");
   return 0;
}

Code explanation

In line 4 we have used the writeln method that allows us to easily output our string in multiple lines. The println would throw an error when you try to output a string in multiple lines. In the example above, the writeln is serving as a string literal that helps to allow a new line of a long text.
