I think there are reserved keywords in C++ , why they are called ‘reserve keywords ‘ and categorized as different?
Words used by the language (
if,for,while,struct, etc.) are sometimes called reserved words or keywords. I suspect that many people also call them reserved keywords.However, there are also words that the Committee may want to use in the future but that aren’t currently used. I would consider these reserved keywords. In Java
gotois a reserved word that isn’t currently used (although I believe the idea is that it won’t ever be used). This kind of reserved keyword isn’t allowed as a variable name, function name,class,structorenumname, etc. But without any use in the language today, it wouldn’t really be allowed in valid C++ at all.
