# About C Programming



 



--> C is a general-purpose programming language.



--> It is Procedural Programming language.



--> It has been used to develop operating systems, databases and applications.



--> It is Middle Level Programming language and gives more control to Programmer.



---

# Mode of Execution used 

GCC Compiler


--> GCC stands for GNU C/C++ Compiler.



--> To begin with GCC, visit the official website  



--> Download GCC according to the platform being used like Linux, MacOs or Windows.



--> Follow the setup wizard.



--> Write c code in any text editor or IDE and save it with .c extention.



--> Then just open the console and run this command -




```

gcc filename.c -o Output

```

--> Filename is the name of the C script file and Output is the name of the output file.



--> After this command is executed, if the code is successfully compiled output file will be saved in the same location as the code file.



--> Once this Output file is executed in command prompt, the output will be displayed.

# Data Types in C






1.Primary Data Types


Primitive data types are the most basic data types that are used for representing simple values such as integers, float, characters, etc.


i) Integer 


--> The integer datatype in C is used to store the whole numbers without decimal values.



--> Octal values, hexadecimal values, and decimal values can be stored in int data type in C. 



    

  • Range:  -2,147,483,648 to 2,147,483,647
    • 

  • Size: 4 bytes
    • 

  • Format Specifier: %d
    • 




ii) Float 


--> In C programming float data type is used to store floating-point values.

 

--> Float in C is used to store decimal and exponential values.



--> It is used to store decimal numbers (numbers with floating point values) with single precision.



    

  • Range: 1.2E-38 to 3.4E+38
    • 

  • Size: 4 bytes
    • 

  • Format Specifier: %f
    • 



iii) Character


--> Character data type allows its variable to store only a single character.



--> The size of the character is 1 byte. It is the most basic data type in C.



--> It stores a single character and requires a single byte of memory in almost all compilers.





    

  • Range: (-128 to 127) or (0 to 255)
    • 

  • Size: 1 byte
    • 

  • Format Specifier: %c
    • 




2. Void


--> The void data type in C is used to specify that no value is present.



--> It does not provide a result value to its caller.



--> It has no values and no operations.



--> It is used to represent nothing. Void is used in multiple ways as function return type, function arguments as void, and pointers to void.




3. Enumerated Type


--> In computer programming, an enumerated type (also called enumeration) is a data type consisting of a set of named values called elements, members, enumeral, or enumerators of the type.



--> The enumerator names are usually identifiers that behave as constants in the language.




i) Enum


--> Enumeration (or enum) is a user defined data type in C. It is mainly used to assign names to integral constants, the names make a program easy to read and maintain.



--> The keyword ‘enum’ is used to declare new enumeration types in C.



4. Derived Data Types 


The data-types that are derived from the primitive or built-in datatypes are referred to as Derived Data Types.



i) Array


--> An array in C is a fixed-size collection of similar data items stored in contiguous memory locations.



--> It can be used to store the collection of primitive data types such as int, char, float, etc., and also derived and user-defined data types such as pointers, structures, etc.


ii) Pointer


--> Pointers are symbolic representations of addresses.



--> They enable programs to simulate call-by-reference as well as to create and manipulate dynamic data structures.



--> Iterating over elements in arrays or other data structures is one of the main use of pointers. 


iii) Structure


--> The structure in C is a user-defined data type that can be used to group items of possibly different types into a single type.



--> The struct keyword is used to define the structure in the C programming language. 



--> The items in the structure are called its member and they can be of any valid data type.


iv) Union


--> A union is a special data type available in C that allows to store different data types in the same memory location.



--> Union can be defined with many members, but only one member can contain a value at any given time.



--> Unions provide an efficient way of using the same memory location for multiple-purpose.
