Identifiers

A Go identifier is a name used to identify a variable, function, or any other user-defined item. An identifier starts with a letter A to Z or a to z or an underscore _ followed by zero or more letters, underscores, and digits (0 to 9).

identifier = letter { letter | unicode_digit }.

Go does not allow punctuation characters such as @, $, and % within identifiers. Go is a case-sensitive programming language. Thus, Manpowerand manpower are two different identifiers in Go. Here are some examples of acceptable identifiers −

mahesh      kumar   abc   move_name   a_123

myname50   _temp    j      a23b9      retVal
