Exploring the Different Types of Data Types in C Language

In C, Datatypes are categorized into derived data types, enumeration data types, and the void data type. following is the categorization 

Basic Data Types:

1.    int:

·         Description: Used to store whole numbers (positive, negative, or zero).

·         Size: Typically 4 bytes (32 bits) of memory.

·         Example: int numberOfBooks = 25;

·         Maximum size: Approximately -2.1 billion to +2.1 billion.

2.    float:

·         Description: Used to store decimal numbers with single-precision.

·         Size: Typically 4 bytes (32 bits) of memory.

·         Example: float height = 1.75;

·         Maximum size: Typically around 6-9 decimal digits of precision.

3.    double:

·         Description: Used to store decimal numbers with double-precision.

·         Size: Typically 8 bytes (64 bits) of memory.

·         Example: double pi = 3.14159;

·         Maximum size: Typically around 15 decimal digits of precision.

4.    char:

·         Description: Used to store individual characters.

·         Size: Typically 1 byte (8 bits) of memory.

·         Example: char grade = 'A';

·         Maximum size: -128 to 127 or 0 to 255, depending on whether it is "signed" or "unsigned".

Derived Data Types:

1.    Array:

·         Description: A collection of elements of the same data type.

·         Example:

int numbers [4] = {1, 2, 3, 4};

2.    Pointer:

·         Description: Pointer is a variable that stores the memory address of another variable.

·         Example:

int *ptr;

int number = 10;

ptr = &number;

3.        3. Structure:

·         Description: A user-defined data type that groups together variables of different data types under one name.

·         Example:

 struct Person

{

   char name[20];

    int age;

   };

    struct Person student;

4.        4. Union:

·         Description: A user-defined data type that allows storing different data types in the same memory location.

·         Example:

        union Data

{

    int number;

    float decimal;

};

union Data value;

                                          

Enumeration Data Type:

1.     1.) enum:

·         Description: Used to define a set of named values.

·         Size: Depends on the number of elements in the enum.

·         Example:

enum fruits {Apple, Mango, Watermelon, Papaya, Jackfruit, Strawberries};

enum fruits King = Mango;

 

 Void Data Type

1.    1.) void:

·         Description: Used to represent the absence of type or absence of a value.

·         Size: Not applicable (void has no size).

·         Example:

               void printHello()

              {

                   printf("Hello!");

               }

If you are beginner in C Language don’t just focus on the code mentioned above for now, even if you understand what are datatypes, what are its types its completely fine in upcoming blogs we will discuss rest of the things make sure you are reading it daily,  just spend 10 minutes reading this blog and you will thank yourself for reading it alright see you soon.
