What Is the Basic Concepts Of C Programming Language?

Basic Concepts Of C Programming Language is an all-purpose programming language. It provides programs of all-purpose, structural programming recursive function programming, and many more. It is regarded as a successor to programming language B.

The C programming language was created by Dennis Ritchie between the years 1972 and 1973. The original design was created to run on a Unix operating system. C language gained huge popularity from the year 1980 when it came to be used by very efficient computer programmers and web architects. The C language got standardized by ANSI in 1989 and by the International Organization of Standardization(ISO).

What is C Programming Language?

The c programming language is also regarded as one of the procedural languages listed in the ALGOL tradition. It provides programs of well-fledged structures maintaining continuity including all kinds of statements. It also gives a lexical scope region within which the variable method is accessible.

It helps the programmer to develop simple and executable codes. While passing the parameters in the functional programming, call by value is preferred more overcall by reference most of the time. Likewise the other languages, statements are terminated by a semicolon(;), and block statements are terminated by curly braces({}) at the opening and closing positions.

Online C Compiler for Beginners

Compiling is a process of converting source code into object code. Basically, the work done by the installed language compiler and the online compiler is the same. The difference is in online mode. Many languages including C give the opportunity to compile their programs online.
Thus below are the most trusted compiling sites-

1- Codepad– compiler and interpreter
2- Codechef– auto-Used for Java,C,C++
3- Ideone.com– compiler and debugging tool
4- Hakerearth– compiler with error highlights
5- JS Fiddle– It consists of 4-panel windows. Three windows are meant for program writing and one for execution.
6- JDoodle– It only do compile after the programmer pastes the written code
7- GCC Explorer – An Interactive Compiler compiler and interpreter
8- DJGPP Public Access Cross- Compiler-compiler and interpreter
9- Test Drive ComeauC/C++Online– compiler and interpreter
10- Online GDB compiler and debugging tool

C compiler

A compiler is a process taker which converts the program written in a high-level language to a low-level language viz. Source code into the object code for the execution of the program.

The source code is considered to be a high-level language meaning the actual program a written by a user in any programming language. Machine code is a set of machine instructions that are interpreted by the virtual machines or CPU directly. Thus compiler’s job is to change the human-written program to machine instructions.

Firstly the compiler usually undertakes a lexing process which means breaking up and division of the program into individual tokens. These tokens are converted in parse tree format which represents sequences of data structures. Then the optimization process undergoes whereby evaluation of every block of statement is done. Thus, the code is converted to machine code.

Objectives- C

Objective- C is the programming language that promotes general programming. Its nature is also object-oriented and it is a style addition to the C programming language. It is used by Apple users for their OSX and iOS types of operating systems.

It provides access to the apple users also to get a tinge of C programming language on their devices. It is used to type simple and executable programs. The language was firstly developed in the year 1980. It was created by Brad Cox and Tome Love at Productivity Products International Company.

After eight years of creation, the language was licensed from NeXT. Here, the class declaration file is called the interface file and the class definition file is named as an implementation file. The methods and functions under the class are directly accessible without any variable or data member.

Turbo C

Turbo C is an IDE meaning Integrated Development Environment for C Programming language. The development credit of Turbo C goes to Borland and it was firstly used publically in the year 1987. Turbo C got famous because of its low price, fast compile speed, comprehensive manual, and its compact size.

This was a web software development tool kit and the programs were written in C language. The Turbo C language was succeeded by Turbo Pascal which was very much used by the teaching professionals because of its teaching essentials features. It has a free download facility from online forums.

Functions of C Programming Language

A function in the programming language can be defined as a group of statements that are provided by the programmer in the program to perform at ask. The must-have function of every C program is the main() function.

Under the main function, the whole program is written. Usually, a program is sequentially constructed in a way that every function has its task to be accomplished. The function prototype is the main declaration line by which we get a clear idea about the function’s name, variable, data type, etc.

The C library also provides certain in-built functions for a user to perform tasks efficiently. Arguments passed are called formal and actual parameters. Values can be passed by a call by value and call by the reference method.

Basic Concepts Of C Programming Language

Basic C programs with Examples

The C language is quite easy and understandable for a beginner. If one wants to start programming on C, he/she should start with the basic programs For eg-simple string programs of names and personal info, arithmetical operations programs like addition, subtraction, multiplication, conversion of a character to its ASCII value, and vice versa, swapping of values, factorials, Fibonacci series, etc.

There are many more in the lists but beginners are suggested to start with basic logic so that it will be easy for them to understand the errors and correct them easily.

Pattern Programs For C

Pattern programs are easy to understand and can be very helpful to beginners in order to get a good hold on loop handlings. These are nothing new but can be defined as patterns of different styles that are drawn by programming. The patterns are of different types like numeric, alpha-numeric, character patterns, symbol patterns, etc. The examples are-

*                                   1                                                    a
* *                                1 1                                                 a b
* * *                             1 1 1                                               a  b c
* * * *                          1 1 1 1                                            a b c d
* * * * *                       1 1 1 1 1                                          a b c d e

Structures in C Programming 

Structures or a struct can be defined as a composite data type declaration in C language. They are the region in which a group of variables is structured in the same memory location and of the same data type. For eg.- char name[50],int numb[100] etc. They are either declared as separate variables in a statement block within curly braces or declared as basic types.

The data type named struct is optional while writing with the variable. The declaration of the structure variable should bed one compulsorily. It is so because the declaration creates and allocates the memory to the variable otherwise the program will not be compiled. When the need for the structure variable arises, the programmer can use the dot(.) operator with the variable name in the program.

To ensure the variables are declared in the format of any particular structure, designated initialization is followed. However, this feature of designated initialization is only available in C. While using a structure pointer,(->) this symbol is used.

There are some limitations also regarding the structure data types in C language like the C language does not give the in-built data type standard to the structure data type. Then +,- data types are not compatible with structure data types. The access modifiers, static variables, and the constructors for the initializations are not permitted inside structures.

The variables do not promote a data hiding facility also.


As mentioned earlier, OnlineGDB is a compiler, editor, tester, and debugger tool for programming languages. The Online GDB is only affiliated with C, C++, and many more programming languages.

It is regarded as the first online IDE debugger and compiler tool. The tool is very useful for programmers who do the programming on an online platform. This helps them to write the programs as well as to correct the errors that erupted in their codes. It also provides a help facility to the users.

In case they need any help, they can type help topics in the application’s frame. There are many features in this application that can be enjoyed by the user when it will be used.

C programming examples

C language can be used in many kinds of programs. For eg- simple programs, array-based including searching and sorting, double and multidimensional array programs for matrices, string-based, stack and queue-based, patterns, file handling, mathematical operations, series, puzzles, function, recursion, and many more. The programs are innumerable and one program can be written with much different logic.

Bubble sort program in C

Bubble sort is a sorting technique for array elements in programming languages. It can be used to arrange the array of elements in both ascending and descending orders. The technique works on the adjacent elements. It checks the adjacent element and swaps it as per the required order. The technique has a set logic for the implementation and is done with the help of a loop.

So, C is the most unique and basic startup language for computers and many more operating systems are built with this C Programming language even though it’s still used for technology. We have highlighted the part and sections of C programming here and the variations also. If u a beginner so hopefully u will clear your concept to read this article. Good Luck!!!!!!!
