Data types In C programming | AsgarTech
In C programming, a data type is a classification of data based on the type of value it represents. Each variable in C programming has a data type that determines the size and type of data that it can hold. The following are the various data types in C programming:

An integer data type is used to represent whole numbers. The size of the integer data type depends on the architecture of the computer. The following are the integer data types in C programming:
char: used to represent a single character, which is typically one byte in size.
short: used to represent integers that are typically two bytes in size.
int: used to represent integers that are typically four bytes in size.
long: used to represent integers that are typically eight bytes in size.
Floating-Point Data Type:
A floating-point data type is used to represent decimal numbers or real numbers. The following are the floating-point data types in C programming:
float: used to represent single-precision floating-point numbers, which are typically four bytes in size.
double: used to represent double-precision floating-point numbers, which are typically eight bytes in size.
Character Data Type:
A character data type is used to represent a single character. The following are the character data types in C programming:
char: used to represent a single character, which is typically one byte in size.
Void Data Type:
A void data type is used to indicate the absence of a value. The following are the void data types in C programming:
void: used as a function return type when the function does not return a value.
Enumerated Data Type:
An enumerated data type is used to represent a set of named values. The following are the enumerated data types in C programming:
enum: used to define a set of named values.
Pointer Data Type:
A pointer data type is used to store the memory address of another variable. The following are the pointer data types in C programming:
int*: used to represent a pointer to an integer variable.
char*: used to represent a pointer to a character variable.
void*: used to represent a pointer to an unknown type of data.
In summary, understanding the different data types in C programming is essential for proper variable declaration and data manipulation. Each data type has its own set of rules and restrictions that need to be followed to ensure efficient and effective programming.
