What are string literals in D programming?
Chinweuba Elijah AzubuikeWhat 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:
- Integer Numeral
- Floating point Numerals
- Characters
- Strings
- 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.
