C Keywords

Hi,
Every programming language as certain predefined words around which whole programming revolves. The meaning and definition of these words are already defined inside the compiler, so variables with same name cannot be created in the program.

In C, there are 32 keywords. The detailed discussions on their meaning and usage will be mentioned as and when they are used in coarse of programming.

Here is the list of all the keywords of C in alphabetical order.

1. auto
2. break
3. case
4. char
5. const
6. continue
7. default
8. do
9. double
10. else
11. enum
12. extern
13. float
14. for 
15. goto
16. if
17. int
18. long
19. register
20. return
21. short
22. signed
23. sizeof
24. static
25. struct
26. switch
27. typedef
28. union
29. unsigned
30. void
31. volatile
32. while

Note:  Some compiler vendors like Microsoft, Borland etc, in addition to above keywords have their own additional keywords also. By convention these vendor specific keywords needs to have their names preceded by 2 underscores (eg. __keyword ). Not every vendor follows this rule.

Next post will be regarding "Constants and Variables in C".

Till then

Happy Learning!!!
