Syntax

A CJam program is generally composed of:

• Literals:
  • numbers such as 1, -5.23, 123456789012345678901234567890
  • strings such as "hello"; the backslash character \ can be used for escaping double quotes and backslashes, nothing else
  • characters such as 'a - note the absence of a second single quote; there is no escape character
• Operators, named with 1 or 2 letters or special characters
• Variables, which can be any single uppercase letter
• Blocks, delimited by { and }

Whitespace (spaces, tabs and new lines) can be used to separate tokens, but usually there is no delimiter needed, with a few exceptions (especially numeric literals).
