Introduction of C language

Hello friends, I am here with the article on C language. We will have a series of C language articles. This is the introductory article of the C 🙂

This article includes following points:-
1) History of C language
2) Features of C language
3) Operators in C language
4) Data types and their categories
5) Applications of C language

1) History of C language

• C Programming language was developed at AT&T Bell laboratories in the year 1972
• C was developed by Dennis Ritchie
• It was developed to solve the problem faced by B language.

2) Features of C language

• Simple:- It is a simple language it provides a structured approach
• Machine Independent:- C language is not dependent on machine
• Middle Level language:- It has the features of both low and high level language
• Structured:- C programs follow a structured approach ie:- the programs can be divided into functions
• Rich library functions:– It has many inbuilt functionality to perform different operations
• Memory Management:- .It has the feature of dynamic memory allocation
• Additional features:– It provides features of Pointers, Recursion etc

3) Operators in C

• Operators in C is a special symbol used to perform the functions.
• The data items on which the operators are applied are known as operands.
• Operators are applied between the operands.
• Depending on the number of operands, operators are classified as follows
• Unary Operator:-
  • A unary operator is an operator applied to the single operand.
  • For example: increment operator (++), decrement operator (–), sizeof, (type)*
• Binary Operator:-
  • The binary operator is an operator applied between two operands.
  • The following is the list of the binary operators:
    • Arithmetic Operators
    • Relational Operators
    • Shift Operators
    • Logical Operators
    • Bitwise Operators
    • Conditional Operators
    • Assignment Operator

4) Data types in C language

• Data types in C refer to an extensive system used for declaring variables or functions of different types.
• The type of a variable determines how much space it occupies in storage and how the bit pattern stored is interpreted
• Following are the examples of some very common data types used in C
  • char: The most basic data type in C. It stores a single character and requires a single byte of memory in almost all compilers
  • int: As the name suggests, an int variable is used to store an integer
  • float: It is used to store decimal numbers (numbers with floating point value) with single precision
  • double: It is used to store decimal numbers (numbers with floating point value) with double precision
• Different categories of Data Types:-
  • Basic Data Types :-int, char, float, double
  • Derived Data Type:- array, pointer, structure, union
  • Enumeration Data Type:- enum
  • Void data type:- Void

5) Application Areas

• C language can be used for developing Compiler
• Can be used in writing Embedded software
• C is used to implement different Operating System Operations.
• C language can be used for creating computer applications.

Thankyou friends we will meet in next article till then bye. And do comment for any quires. Once again Thankyou 🙂
