How Many Keywords Are There in C++
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++
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 more readable alternatives for some of the C++ operators, and also to facilitate programming with character sets that lack characters needed by C++.
Here is a list of all these reserved words:
