2. **break:** Loop ya switch statement ke bheetar se bahar nikalne ke liye istemal hota hai.

3. **case:** Switch statement mein specific value ke liye code block ko define karne ke liye istemal hota hai.

4. **char:** Character data type ko declare karne ke liye istemal hota hai.

5. **const:** Variable ko constant banaane ke liye istemal hota hai, jisse ki uski value program ke execution ke dauraan change nahi ho sakti.

9. **double:** Double-precision floating-point number data type ko declare karne ke liye istemal hota hai.

10. **else:** If statement ke sath istemal hota hai aur if condition false hoti hai to alternative code block ko define karne ke liye istemal hota hai.

11. **enum:** Enumeration data type ko declare karne ke liye istemal hota hai, jisse aap user-friendly names se associated values ko use kar sakte hain.

12. **extern:** External variable ko declare karne ke liye istemal hota hai, jisse dusre files mein access kiya ja sakta hai.

13. **float:** Floating-point number data type ko declare karne ke liye istemal hota hai.

14. **for:** Loop ko define karne ke liye istemal hota hai.

15. **goto:** Program mein specific location pe jump karne ke liye istemal hota hai, lekin ise dhyan se istemal karna chahiye kyunki yeh code readability ko kharab kar sakta hai.

16. **if:** Conditional statement ko define karne ke liye istemal hota hai.

17. **int:** Integer data type ko declare karne ke liye istemal hota hai.

18. **long:** Long integer data type ko declare karne ke liye istemal hota hai.

19. **register:** Variable ko register storage class mein declare karne ke liye istemal hota hai.

20. **return:** Function se control ko wapas karne ke liye istemal hota hai aur ek value ko wapas karne ke liye bhi istemal hota hai.

21. **short:** Short integer data type ko declare karne ke liye istemal hota hai.

22. **signed:** Variable ko signed storage class mein declare karne ke liye istemal hota hai.

23. **sizeof:** Variable ya data type ka size (in bytes) determine karne ke liye istemal hota hai.

24. **static:** Variable ko static storage class mein declare karne ke liye istemal hota hai, jisse uska scope program ke execution ke samay tak rehta hai.

25. **struct:** Structure data type ko declare karne ke liye istemal hota hai, jisse multiple data fields ko ek saath store kiya ja sakta hai.

26. **switch:** Switch statement ko define karne ke liye istemal hota hai, jisse multiple conditions ke liye code blocks ko execute kiya ja sakta hai.

27. **typedef:** Custom data type ko define karne ke liye istemal hota hai.

28. **union:** Union data type ko declare karne ke liye istemal hota hai, jisse multiple data types ke variables ko ek memory location mein store kiya ja sakta hai.

29. **unsigned:** Variable ko unsigned storage class mein declare karne ke liye istemal hota hai, jisse ve sirf non-negative values ko represent karen.

30. **void:** Function mein return type na ho ya koi value return na ho to void data type ka istemal hota hai.

31. **volatile:** Variable ko volatile storage class mein declare karne ke liye istemal hota hai, jisse compiler optimization se bacha ja sakta hai.

32. **while:** While loop ko define karne ke liye istemal hota hai.

Yeh sirf kuch common C Language keywords hain. C Language mein aur bhi keywords hote hain, aur kuch specific compilers ya libraries bhi apne khud ke keywords istemal kar sakte hain.
