What are the datatypes in C?

In C, there are several built-in data types that are used to define variables and constants:
int:Integer data type, used for whole numbers
float: Single-precision floating-point data type, used for decimal numbers
double: Double-precision floating-point data type, used for decimal numbers with more precision
char: Character data type, used to store a single character
void: Used to indicate that a function does not return a value or that a variable has no type
_Bool: Boolean data type, used to store true or false values
In addition to these built-in data types, C also allows for the creation of user-defined data types using structs and typedefs.

Data types in C are used to define the type of values that variables can hold and the operations that can be performed on them. There are four basic data types: int, char, float, and double. int stores integers, char stores characters, float stores decimal numbers with limited precision, and double stores decimal numbers with higher precision. There are also derived data types, such as arrays, pointers, structures, and unions. Arrays group elements of the same type, pointers hold memory addresses of other variables, structures combine different data types under a single name, and unions allow different data types to share the same memory space. Modifiers such as signed, unsigned, short, and long can be used to change the size and range of an integer type.
