C Tutorial

Overview

Welcome to the C Tutorial by C Experts. The objective of these tutorials is to provide a depth understanding of the C language. In these tutorials, we will cover topics such as operators, statements, loops, pointers, functions, arguments,  recursions and classes.

In addition to free C Tutorials, we will also cover common interview questions and issues of C language.

History of C Language

The programming language term is started in the year of 1950s with the language called ‘Aron’.

From FORTRAN language another programming language is implemented although.

ALGOL

An acronym for algorithmic language.

The beginning of ‘c’ is started in the year 1968 with the language called BCPL which is evaluated by “Martin Richard”

BCPL

Basic combined programming language.

In the year 1970 from BCPL, another programming language is implemented called “B” Language which is developed by “Ken Thompson”. In the year 1972 “Dennis Ritchie” is implemented ‘C’ programming language at AT&T Bell laboratories for developing the system software. In the year 1988 ‘c’ programming language standardised by ANSI-C that version is called ANSI-C version.

ANSI

American National Standard Institute.

In the year 2000 ‘C’ programming language standardised by ISO that version is “c99”.

C+simula 68 -> c++

Advantages of C

Portability

It is a concept of carrying instructions from one system to another system.

As per the above observation, when we are copying .exe file to any other computer which contains the Windows operating system, then it works properly because the native code is the same. Same “.EXE@ file when we are copying to any other system which contains Unix/Linux operating system so this behaviour is called platform dependency. When we are copying the application file from one operating system to another operating system. If it works properly, then it is called platform independent. It doesn’t work then it is called “platform dependent”. C programming language is a platform-dependent machine-independent programming language(Hardware independent)

Molecularity

It is a concept of developing an application in sub-modules or sub-programmes. I.e. procedure-oriented approach.

Midlevel

C programming language can support high-level instruction with the combination of assembly language code. So, it is called a midlevel programming language.

Simple

This programming language syntactically similar to English and limited concepts is available.

Applications of C

C-programming language can be used to design different types of application like designing the system software like OS & compiler. Designing the application software like database & spreadsheets. To design the graphics related applications i.e. pc’s and mobile games. To evaluate the mathematical equations.
