C Programming Tutorial

I this C Programming tutorial we will learn about, What is C Programming Language?, What is use of C Programming Language?, and What are the features of C Programming Language?

What is C programming language?

C programming language was initially developed by Dennis Ritchie between 1969 and 1973.C language was mainly developed as a system programming language to write an operating systems like windows,linux etc .The main features of C-Programming-language include low level access to memory, a simple set of keywords, and clean style.These features make C programming language suitable for system programmings compiler development or an operating system.C programming language is a general purpose programming language, which relates closely to the way how machines work.It is very close to the low level language and it also woks as like high level programming language.It is extremely powerfull,popular,simple and flexible. It is machine independent and also structured programming language.

What is the use of C programming language?

The C language has formed the base of many languages including C++, C-, C#, Objective-C, BitC, C-shell, csh, D, Java, JavaScript, Go, Rust, Julia, Limbo, LPC, PHP, Python, Perl, Seed7, Vala, Verilog and many more other languages.

As it is a middle-level language, C combines the features of both high level and low level languages. So it can be used for low level programming, such as scripting for drivers and kernels. It also support the functions of high level programming languages, such as scripting for software applications etc. C programming language is evaluated as the base for other programming languages. That is why it is known as the mother of programming language.

C programming language tutorial with a programming technique for beginners and professionals and it helps you to know the C programming language tutorial skillfully. Our C tutorial clarifies each theme with programs.

It can be specified in the additional ways:

  1. Mother language.
  2. System programming language.
  3. Procedure-oriented programming language.
  4. Structured programming language.
  5. Mid-level programming language.

1) C as a mother language :

C programming language is assumed as the mother language of all the new programming languages. Because most of the compilers, JVMs, Kernels, etc are written in the C programming language. And most of the programming languages follow C syntax. For example, C++, Java, C#, etc.

It gives the core concepts like the array, strings, functions, file handling, etc. That is being employed in various languages like C++, Java, C#, etc.

2) C programming language as a system programming language :

A system programming language is used to build system software. C programming language is a system programming language because it can be manipulated to do low-level programming. For example, (driver and kernel). It is mostly used to create hardware equipment, OS, drivers, kernels, etc. For example, the Linux kernel is written in the C programming language.

It can't be manipulated for internet programming like Java, .Net, PHP, etc.

3) C as a procedural language:

A procedure language is understood as a function, method, routine, subroutine, etc. A procedural language indicates a series of walks for the program to understand the difficulty.

A procedural language smashes the program into functions, data structures, etc.

C programming language is a procedural language. In C, variables and function prototypes must be announced before being manipulated.

4) C as a structured programming language:

A structured programming language is a subset of procedural speech. Structure means to smash a program into parts or blocks so that it may be easy to discern.

In the C programming language, we break the program into parts using functions. It makes the program simpler to understand and improve.

5) C as a mid-level programming language:

C programming language is considered a middle-level language because it benefits the detail of both low-level and high-level languages. C programming language is converted into assembly code and it supports pointer arithmetic (low-level), but it is device independent (a feature of high-level).

A Low-level language is particular to one machine, i.e., machine-dependent. It is machine-dependent, fast to run. But it is not easy to understand.

A High-Level language is not particular to one machine, i.e., machine-independent. But it is simple to understand.

What are the features of C Programming Language?

C programming is comprehensively used language over the world. It contains many features which are written below.

  1. Simple
  2. Machine Independent or Portable
  3. Structured programming language
  4. Mid-level programming language .
  5. Rich Library.
  6. Fast Speed
  7. Memory Management .
  8. Recursion
  9. Pointer
  10. Extensible
Features of c-programming


As a language, C program is a easy language in the mean that it yields a well-structured approach ( to separate the problems in multiple parts), the enriched set of data types, library functions etc.

2.Machine Independent or Portable:

Unalike the assembly language, c program can be performed on various machines altering some specific changes. Thus, we call C program a machine independence language.

3.Structured programming language:

C is a structured programming language in the sense of that we can separate the program into smaller parts by the help of functions. So, it is quite simple to understand and modify. Functions also transmits code reusability.

4.Mid-level programming language:

Though C is executed to do lower level programming, it is also used for development of system applications such as drivers, kernel etc. It also copes up with higher level languages. For this C is called a Mid-level language.

5.Rich Library:

C provides a lot of integral functions that make the development faster.

6.Fast Speed:

The time for compilation and execution of C language is faster than other languages as there are lesser inbuilt functions and thus the lesser overhead.

7.Memory Management:

It supports dynamic memory allocation features . In C , we can set free the allocated memory at any time by calling the free () function.


In C, we can call out the function within the function. It yields code reusability for each and every function. Recursion allows us usage the approach of backtracking.


C language provides the feature of pointers. We can easily interact with the memory by using the pointers. We can use pointers for arrays ,memories, functions, structures, etc.


Since C language can cope up with new features, it is extensible.

In this c programming tutorial, all C programs are given with a C compiler so that you can fast change the C program code.
