A standard identifier is a reserved word. Keywords such as for, if, goto, return, continue, break, do, while, final, extern, static and so on are all reserved. Fundamental data types and modifiers such as void, int, char, wchar_t, double, float, long, short, signed, unsigned, const, mutable, constexpr and so on are also reserved. A user-defined identifier is any name (function, class, namespace or alias) that is not a reserved word.

What is an undeclared identifier?
An undeclared identifier is a variable, function, or other identifier that has not been defined or declared in a program's scope before it is used. This typically results in a compilation error, as the compiler cannot recognize the identifier. To resolve this issue, the programmer must ensure that the identifier is properly declared before its usage. This concept is crucial in programming languages that require explicit declarations, such as C, C++, and Java.
