What is the function of keywords in the C language?

Answer 1

Keywords are reserved words in a programming language whose meaning are available in the respective compiler. C Programming language has the following keywords; default, return, struct, void, volatile, unsigned, signed, double, while, union, static, switch, typedef, register, short, size of, for, long, if, int, goto, enum, float, else, extern, do, const, break, char, case, break and auto.

Answer 2

extern, static, auto, typedef, struct, union, enum, register, volatile, void, const, signed, unsigned, short, long, char, int, float, double, if, else, while, do, for, switch, break, continue, default, return, goto, sizeof ... etc.

Answer 3

Keywords are the base building blocks of any computer language. ALL functions in a computer language is built upon these and "operators". Other components include literals and variables and much more.

Keywords define the basics that tell the compiler of the language "this is a number", "this can't be changed", "this only exists once".

Operators perform math. In the case of "x = 1 + 2". x is a variable. 1 and 2 are "numerical constants" and = and + are called operators. = is the "assignment operator" and + is the "addition operator".

If you write "const int x = 5;".

- const is a keyword that tells the compiler that this value will be set here and now and will remain constant afterwards. If someone tries to change it, stop them.

- int is a keyword which means "integer" or in most implementations of C, "a 32-bit integer that can be positive or negative".

- x is a variable, so from now on, whenever you see x, it means....

- = is the assignment operator saying that x should contain what comes after

- 5 is a numerical constant meaning... well 5

- ; is punctuation. It means this is the end of the statement. It's like a period in American English (or full stop in British).

Answer 4

Keywords are the set of words in C language whose meaning and actions remains fixed throughout the language. We cannot use the following 32 keywords as variable name

auto, break, case, char, const, continue, default, do, double, else, enum, extern, float, for, goto, if, int, long, register, return, short, signed, sizeof, static, struct, switch, typedef, union, unsigned, void, volatile, while

Answer 5

Your question (if it is a question at all) doesn't make sense; it is like as if you asked 'define verbs in English.'

Answer 6

Words with special meanings like if, else, for, enum...

they cannot be used as identifiers.

Answer 7

well there are a lot!

so Google it : c keywords.

Answer 8

More than one, examples: for, while, break, typedef.

Answer 9

Key words are reserve words which meaning is all ready in compiler means which meanig is that the computer know these words,,in c language we use many keywords like int flot char
