It depends on the context. If used in a declaration, it means that the identifier is declared a pointer to a named type. If used in an expression, it means that you wish to dereference a pointer. A pointer is used to store memory addresses. Dereferencing a pointer allows the programmer to access the value stared in the memory address. In other words, it provides indirect access to the value stored in the memory address being pointed at.
int i, *p; /* declare an integer and a pointer to an integer */
p = &i; /* store the address of i in p (point to i)*/
*p = 42; /* store the value 42 in that address (dereference) */
assert (i==42); /* assert that i now holds the value 42 */
It mean the content of that identifier.
No. Identifier is a scientific name for the name.Variables, functions, types, etc -- each have an identifier.
No. Neither is a10 and A10.
letter -> [a-zA-Z] digit -> [0-9] identifier -> letter|_(letter|digit|_)
It's by design; this way the lexical parser is able to decide that any given string is a keyword or an identifier.
Identifiers or symbols are the names you supply for variables,type,function and labels.Identifiers names must differ in spelling and case from any keyword.you cannot use keyword as an identifier.you can create an identifier by specifying it in the declaration of a variable,type or function.
An identifier is the names given for labels, functions and variables in the c language.

An identifier is a name. All names must be declared with a type.
C is a programming language.
Yes. The word "hello" can be an identifier token. It is not a reserved word in C or C++, and it meets the criteria for being an identifier.
It is not a reserved word, so can be an identifier (name of a type/variable/function).
If you mean 'are identifier of an object and nameof an object synonyms?', then yes, they are.
