C Keywords
1. Keywords are the words whose meaning has already been
explained to the C compiler.
2. The keywords
cannot be used as variable names because if we do so we are trying to assign a
new meaning to the keyword, which is not allowed by the computer.
3. Some C
compilers allow you to construct variable names that exactly resemble the
keywords.
4. However, it would be safer not to mix up the variable names and the
keywords. The keywords are also called ‘Reserved words’.
5. There are only 32 keywords available which gives
a list of these keywords for your ready reference.
6. A detailed discussion of
each of these keywords would be taken up in later chapters wherever their use
is relevant.
Note that compiler vendors (like Microsoft, Borland, etc.)
provide their own keywords apart from the ones mentioned above.
These include
extended keywords like near, far, asm, etc.
