Overview of C Language

Overview of C Language Tutorials

C programming – is a procedural, imperative, general-purpose computer programming language. It was created by Dennis M. Ritchie at Bell Telephone Laboratories in 1972 to develop the UNIX operating system. C remains at the top of the popularity rankings, alongside Java, for software programming languages.

What is C Programming Language?

C is a general-purpose programming language that is extremely popular, simple, and flexible to use. It is a structured programming language that is machine-independent and extensively used to write various applications, Operating Systems like Windows, and many other complex programs like Oracle database, Git, Python interpreter, and more.

Why to Learn C Programming?

As we studied earlier, ‘C’ is a base language for many programming languages. So, learning ‘C’ as the main language will play an important role while studying other programming languages. It shares the same concepts such as data types, operators, control statements and many more. ‘C’ can be used widely in various applications. It is a simple language and provides faster execution. There are many jobs available for a ‘C’ developer in the current market.

C is a compiled language. A compiler is a special tool that compiles the program and converts it into the object file which is machine readable. After the compilation process, the linker will combine different object files and creates a single executable file to run the program. The following diagram shows the execution of a ‘C’ program.

History of C language

‘ALGOL’ is the foundation or father of all programming languages. In 1960, it was initially introduced. In many European countries, ‘ALGOL’ was widely utilized. The concept of structured programming was first introduced to the developer community by ‘ALGOL’. A new computer programming language named ‘BCPL’. which stands for Basic Combined Programming Language, was announced in 1967.

Advantages of C Programming

  • Easy to learn
  • Structured language
  • It produces efficient programs
  • It can handle low-level activities
  • It can be compiled on a variety of computer platforms
  • It is simple to comprehend.
  • a large number of libraries
  • It’s simple to write
  • Cost-effective
  • Quick execution time
  • Portable
  • Procedure Oriented Language is simple to debug.
  • Speed of Compilation Algorithms and data structures are executed quickly.
  • Memory allocation that is dynamic

What are the disadvantages of C language?

  • Object Orientation Deficit
  • Memory Management is inefficient.
  • There is no garbage collection.
  • Checking at runtime
  • In C, there is no concept of a namespace.
  • Exception Handling isn’t present.
  • Constructor and Destructor aren’t present.

C Programs

A C program can include anything from three to millions of lines and should be written in one or more text files with the extension “.c,” such as hello.c. You may write your C program into a file using “vi”, “vim,” or any other text editor.

This lesson assumes that you can edit a text file and write source code within a program file.


An overview of the C language and its history was the main focus of this session. Dennis Ritchie created C in 1972 at AT&T’s Bell Laboratories. We shall study the features of the C language in detail in the upcoming tutorial.
