Specific compilers may also have additional specific reserved keywords. Very important: The C language is a 'case sensitive' language. That means that an identifier written in capital letters is not equivalent to another one with the same name but written in small letters. Auto break case: char: const: continue: default: do double else: enum: extern float far: goto: if: int: long: register: return: short: signed: sizeof. Learn how to program in C with Dev-C IDE.

Keywords
This page contains a list of allthe reserved words in Standard C++,and a few predefined identifiersfor the sake of comparison.
Recall the distinction between reservedwords and predefined identifiers,which are collectively referred to (by us, atleast) as keywords. But be aware thatthis terminology is not standard. For example,some authors will use keyword in thesame sense that we have used reserved word.
C++ Reserved Words
The reserved words of C++ may be conveniently placed into severalgroups. In the first group we put those that were also present in theC programming language and have been carried over into C++. There are32 of these, and here they are:There are another 30 reserved words that were not in C, are thereforenew to C++, and here they are:The following 11 C++ reserved words are not essential when the standardASCII character set is being used, but they have been added to providemore readable alternatives for some of the C++ operators, and also tofacilitate programming with character sets that lack characters neededby C++.Note that your particular compiler may not be completely up-to-date,which means that some (and possibly many) of the reserved words inthe preceding two groups may not yet be implemented.
Some Predefined Identifiers
Beginning C++ programmers are sometimesconfused by the difference between thetwo terms reserved word andpredefined identifier, andcertainly there is some potential forconfusion.
One of the difficulties is that somekeywords that one might 'expect'to be reserved words just are not.The keyword main is a primeexample, and others include thingslike the endl manipulator andother keywords from the vastcollection of C++ libraries.
For example, you could declare avariable called main insideyour main function, initializeit, and then print out its value (butyou probably shouldn't, except asan experiment to verify that you can!).On the other hand, you could notdo this with a variable named else.The difference is that else isa reserved word, whilemain is 'only' a predefinedidentifier.
Here is a very short list of some of the predefined identifiers you mayhave encountered:

Keywords are those words whose meaning is already defined by Compiler. These keywords cannot be used as an identifier. Note that keywords are the collection of reserved words and predefined identifiers. Predefined identifiers are identifiers that are defined by the compiler but can be changed in meaning by the user.

There are a total of 95 reserved words in C++. The reserved words of C++ may be conveniently placed into several groups. In the first group, we put those that were also present in the C programming language and have been carried over into C++. There are 32 of these.
There are another 30 reserved words that were not in C, are therefore new to C++ programming language.
There are 11 C++ reserved words that are not essential when the standard ASCII character set is being used, but they have been added to provide readable alternatives for a few of the C++ operators, and also to facilitate programming with character sets that lack characters required by C++.
