What does the word ‘literal’ mean when used in context such as literal strings and literal values?
What is the difference between a literal value and a value?
A literal is ‘any notation for representing a value within source code’ (wikipedia)
(Contrast this with identifiers, which refer to a value in memory.)
Examples:
'hey'(a string)false(a boolean)3.14(a real number)[1,2,3](a list of numbers)(x) => x*x(a function)/^1?$|^(11+?)\1+$/(a regexp)Some things that are not literals:
std::cout(an identifier)foo = 0;(a statement)1+2(an expression)
