C Programming Tutorial for Beginners

C Programming Tutorial is a procedural, imperative, general-purpose computer programming language created by Dennis M. Ritchie.

At Bell Telephone Laboratories in 1972, it developed the UNIX operating system.

The most widely used programming language is C.

It remains at the top of the popularity rankings, alongside the Java programming language, which is also very popular and widely used among current software programmers.

What is C Programming Language?

C programming tutorials is a popular, simple, and flexible general-purpose language.

It is a structured programming language that is machine-independent.

It is extensively used to write various applications. Operating systems such as Windows.

The other complex programs include Oracle database, Git, Python interpreter, and others. 

Why 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. Many jobs are available for a “C” developer in the current market.

How C Programming Language Works?

C is a compiled language. A compiler is a special tool that compiles the program and converts it into an object file that is machine-readable.

After the compilation process, the linker will combine different object files and create a single executable file to run the program. The following diagram shows the execution of a ‘C’ program.

Where is C used? Key Applications

  • In embedded systems, c programming tutorials are commonly employed.
  • It’s a programming language that’s used to create system applications.
  • It’s extensively used for desktop application development.
  • The majority of Adobe’s programs are written in the C programming language.
  • It is used in the development of browsers and addons. The ‘C’ programming language is used to create Google’s Chromium.
  • It is employed in the creation of databases. MySQL is the most widely used database program written in C.
  • It’s employed in the creation of operating systems. The ‘C’ programming language is used to create operating systems such as Apple’s OS X, Microsoft’s Windows, and Symbian. It is used to create operating systems for both desktop computers and mobile phones.
  • It’s utilized in the creation of compilers.
  • It’s commonly utilized in Internet of Things (IoT) applications.

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’.

Dennis Ritchie, a brilliant computer scientist, devised the “C” programming language at Bell Laboratories in 1972. It was built using the programming languages ‘ALGOL’, ‘BCPL’, and ‘B’.

All of these properties are present in the ‘C’ programming language. as well as a number of other notions that distinguish it from other languages.

History of C

The following reasons make C Programming a widely used professional language:

  • It is a robust language.
  • It is a low programming level language close to machine language
  • It is widely used in the software development field.
  • It is a procedure and structure oriented language.
  • It has the full support of various operating systems and hardware platforms.
  • Many compilers are available for executing programs written in ‘C’.
  • A compiler compiles the source file and generates an object file.
  • A linker links all the object files together and creates one executable file.
  • It is highly portable.

  • Clang compiler
  • MinGW compiler (Minimalist GNU for Windows)
  • Portable ‘C’ compiler
  • Turbo C

C Programming Language Basic Commands

C Language Basic commandsExplanation
#include <stdio.h>Before constructing a C program, this command includes the standard input output header file (stdio.h) from the C library.
int main()It is the main function that starts the execution of a C program.
{This specifies the start of the main function.
/*_some_comments_*/Whatever is written within the “/* */” command in a C program will not be evaluated for compilation or execution.
printf(“Hello_World! “);The output of this command is displayed on the screen.
getch();Any character input from the keyboard is handled by this command.
return 0;This command returns 0 after terminating a C program (main function).
}It’s used to signify that the main function is finished.

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.

Facts about C Programming

  • C was invented to write an operating system called UNIX.
  • C is a successor of B language which was introduced around the early 1970s.
  • The language was formalized in 1988 by the American National Standard Institute (ANSI).
  • The UNIX OS was totally written in C.
  • Today C is the most widely used and popular System Programming Language.
  • Most of the state-of-the-art software has been implemented using C.

C Programming Application

C was first used for system development, namely for the programs that make up an operating system. C was chosen as a system development language.

Because it generates code that runs nearly as quickly as assembly language code. The following are some examples of C usage:

  • Databases
  • Language Interpreters
  • Utilities
  • Print Spoolers
  • Network Drivers
  • Modern Programs
  • Assemblers
  • Text Editors
  • Operating Systems
  • Language Compilers
