String literals can be used as either array initializers or expressions of type `pointer`.
|
||||
|
||||
If a string literal is used as an expression, then the text data will be located in the default code segment,
|
||||
regardless of which code segment the current function is located it. This may be subject to change in future releases.
|
||||
|
||||
String literals are surrounded with double quotes and optionally followed by the name of the encoding:

|

"this is a string" ascii
