Keywords in C++

The keywords are identifiers but cannot be user defined, since they are reserved words. So, keywords are also known as reserved words. We should not use them as variables or identifiers.All the keywords  should be in lowercase letters.Some  Keywords are:

auto          const               for              new                signed            try

asm           default             float          operator       sizeof              typedef
