What do you meant by c keyword

In the C programming language, keywords are special reserved words that have specific meanings and cannot be used for other purposes in your code. They are the building blocks of C’s syntax, the set of rules that defines how the code is written.

Here are some key points about C keywords:

Reserved: You cannot use C keywords as variable names, function names, or any other user-defined identifiers.
Case-sensitive: C is case-sensitive, so int and Int are considered different.
Define Program Structure: Keywords control the flow of your program, like loops, conditionals, and function calls. They also define data types and other fundamental aspects of the code.
Here are some examples of common C keywords and their functions:

int: Declares an integer variable.
float: Declares a floating-point variable (numbers with decimals).
char: Declares a single character variable.
if: Starts a conditional statement.
else: Defines the alternative path in a conditional statement.
for: Starts a loop that repeats a block of code.
while: Starts a loop that continues to execute as long as a condition is true.
return: Exits a function and optionally returns a value.
