Keywords Available in Both C and C++

C and C++ share a set of keywords since C++ was initially designed as an extension of the C language. Here are the keywords available in both C and C++:

 

1. auto: Specifies automatic storage duration for a variable.
2. break: Terminates the execution of a loop or switch statement.
3. case: Labels a statement within a switch statement.
4. char: Defines a character data type.
5. const: Specifies that a variable's value cannot be modified.
6. continue: Skips the current iteration of a loop and proceeds to the next iteration.
7. default: Specifies the default case in a switch statement.
8. do: Initiates a do-while loop.
9. double: Defines a double-precision floating-point data type.
10. else: Specifies the alternative condition in an if statement.
11. enum: Declares an enumeration type.
12. extern: Specifies external linkage for a variable or function.
13. float: Defines a single-precision floating-point data type.
14. for: Initiates a for loop.
15. goto: Transfers control to a labeled statement.
16. if: Initiates an if statement.
17. int: Defines an integer data type.
18. long: Defines a long integer data type.
19. register: Suggests to the compiler to store a variable in a register.
20. return: Returns a value from a function.
21. short: Defines a short integer data type.
22. signed: Specifies signed integer types.
23. sizeof: Returns the size of a data type or variable.
24. static: Specifies static storage duration for a variable or function.
25. struct: Defines a structure type.
26. switch: Initiates a switch statement.
27. typedef: Creates an alias for a data type.
28. union: Defines a union type.
29. unsigned: Specifies unsigned integer types.
30. void: Specifies an empty or incomplete data type.
31. volatile: Indicates that a variable may be modified by external factors.
32. while: Initiates a while loop.

 

These keywords are part of the core syntax and semantics shared by both C and C++, allowing developers to write code that is compatible with both languages. However, while these keywords are common, there are differences in the way some features are implemented or used between C and C++.
