An invalid character in an identifier is a character that is not allowed in the name of a variable, function, class, or any other identifier in a programming language. Typically, identifiers in programming languages are composed of letters, digits, and certain special characters like underscore (_).
If an invalid character is used in an identifier, the compiler or interpreter will generate an error message indicating that the identifier is not recognized. Common examples of invalid characters include spaces, hyphens, and punctuation marks like commas and periods. It is important to follow the rules for naming identifiers in a programming language to avoid errors and ensure that code is readable and maintainable.
