<p dir="ltr">Language is a way of communication between two or more mediums. Programming is the language for computers or applications that are used for giving commands and instructions to the system.&nbsp;</p>
<p dir="ltr">Programming languages are used by developers to create instructions that are meant to perform a particular task on the computer.</p>
<p dir="ltr">Knowing about programming helps in learning advancements in the IT sector, which is the game-changer in how computers are used in modern times. A computer language is also known as a programming language and is used to create software programs, apps, and scripts. Developers or programmers can give commands to computers with the help of programming languages.</p>
<p dir="ltr">The programming done by the user is processed by the machine language, and the computer understands the instructions through that.</p>
<p dir="ltr">There are tens of thousands of languages created now, but only a handful of them are used on a big scale. Languages like <a href="https://www.tutorialsfreak.com/c-programming-tutorial" target="_blank" rel="noopener">C</a>, C++, <a href="https://www.tutorialsfreak.com/python-tutorial" target="_blank" rel="noopener">Python</a>, <a href="https://www.tutorialsfreak.com/java-tutorial" target="_blank" rel="noopener">Java</a>, <a href="https://www.tutorialsfreak.com/kotlin-tutorial" target="_blank" rel="noopener">Kotlin</a>, JavaScript, PHP, and R languages are popular names among programmers.&nbsp;</p>
<p dir="ltr">In addition to the <a href="https://www.tutorialsfreak.com/c-programming-tutorial" target="_blank" rel="noopener">C language tutorial</a>, we have also crafted a comprehensive<a href="https://www.tutorialsfreak.com/python-tutorial" target="_blank" rel="noopener"> Python tutorial for beginners</a>. You can check that out by clicking on the linked page.</p>

<p dir="ltr">Computer programming is generally of three types:</p>
<h3 dir="ltr" role="presentation">1. Low-level programming languages</h3>
<p dir="ltr">This language is machine-run and can understand only 0 and 1. The processor runs fast in it, and it does not require any compiler. It requires further continuous instructions from programmers to run smoothly.&nbsp;</p>
<h4 dir="ltr">Further, low-level language can be divided into two parts.</h4>
<ul>
<li dir="ltr" aria-level="1">
<h5 dir="ltr" role="presentation">Machine language</h5>
</li>
</ul>
<p dir="ltr">It is written in binary or hexadecimal form. It is not presented in mathematical language for humans to understand. Codes in machine language are different on every computer, which is why machine languages are tough to write.</p>
<ul>
<li dir="ltr" aria-level="1">
<h5 dir="ltr" role="presentation">Assembly language</h5>
</li>
</ul>
<p dir="ltr">The Assembly language is a step ahead of machine language. It allows programmers to assign values to codes. Programs can be written in short instead of writing full binary or hexadecimal.</p>
<p dir="ltr">It can be easily translated into machine language. It is very useful when peripheral devices are connected to the computer as it needs detailing about the computer system.</p>
<h3 dir="ltr" role="presentation">2. Middle-level programming languages</h3>
<p dir="ltr">Middle-level languages stand somewhere near low-level and high-level programming languages. It is also known as pseudo-language.</p>
<p dir="ltr">These languages are close to machine language, and it also supports high-level programming.</p>
<p dir="ltr">C language is an example of a middle-level programming language.</p>
<h3 dir="ltr" role="presentation">3. High-level programming languages</h3>
<p dir="ltr">High-level programming languages are the most complex ones. They need a compiler or interpreter to execute a program.</p>
<p dir="ltr">High-level programming languages can be divided into three further parts:</p>
<ul>
<li dir="ltr" aria-level="1">
<p dir="ltr" role="presentation">Procedural Oriented Programming (POP)</p>
</li>
<li dir="ltr" aria-level="1">
<p dir="ltr" role="presentation">Object-Oriented Programming (OOP)</p>
</li>
<li dir="ltr" aria-level="1">
<p dir="ltr" role="presentation">Natural Programming</p>
</li>
</ul>
<p dir="ltr">Languages like <a href="https://www.tutorialsfreak.com/python-tutorial" target="_blank" rel="noopener">Python</a>, PHP, C++, and <a href="https://www.tutorialsfreak.com/java-tutorial" target="_blank" rel="noopener">Java</a> are some examples of high-level programming languages.</p>

<p dir="ltr">C is one of the most popular and oldest programming languages. It was developed by Dennis Ritchie and Brian Kernighan in 1972.&nbsp;</p>
<p dir="ltr">It is a general-purpose, high-level programming language that has been an integral part of the computer programming landscape for over four decades. Known for its efficiency, versatility, and ability to handle low-level tasks, C has been used in the development of many of the world's most influential software systems.</p>
<p dir="ltr">C programming language gives programmers a free hand in operating data addresses and values in the data. It is used in various fields as it is a combination of both high and low-level languages. In simple words, C language is a middle-level programming language that is used to develop programs with low difficulty levels.</p>
<p dir="ltr">It is used in application development, game creation, driver development, program development, text editors development, compilers, <a href="https://www.tutorialsfreak.com/ai-tutorial" target="_blank" rel="noopener">artificial intelligence</a>, and other software.</p>
<p dir="ltr">C is faster in process, structure-oriented, and can be extended easily. It is used in complex calculations and operated in MATLAB.</p>

<p dir="ltr">Here is an example of a program in which C language is used:</p>
<pre class="language-c"><code>#include 
int main ()
{
Printf (&ldquo;Hello World! \n&rdquo;)
}
Output:
&ldquo;Hello Word!&rdquo;
</code></pre>
<p dir="ltr">In this program, the #include line includes the standard input/output header file, which contains definitions for the printf function. The main function is the entry point of the program, and printf is used to print the message "Hello, World!" to the console.&nbsp;</p>
<p dir="ltr">The major achievement in C was the UNIX operating system, which laid the foundation for C language, and then many languages rose with advanced updations like C++, C#, Java, etc. Hope you now have a good idea of what is C programming definition.</p>

<p dir="ltr">Let&rsquo;s know about the<a href="https://www.tutorialsfreak.com/c-programming-tutorial/c-programming-history" target="_blank" rel="noopener"> <strong>history of C programming language</strong></a> now. Initially, the programs were written in binary form, and then machine languages were named first-generation languages.&nbsp;</p>
<p dir="ltr">After that, second-generation programming languages (assembly languages) were introduced. The third generation of programming language, or the first generation of a high-level language, was written in the 1950s.</p>
<p dir="ltr">Between 1969 and 1973, the C programming language was introduced, which was developed by Dennis Ritchie for the UNIX Operating System. C is considered the mother language of all languages, as it is the base for other programming languages.</p>
<p dir="ltr">Currently, it is used in many organizations, including big names like Apple, Microsoft, and Oracle. Industries like engineering, IT, management, healthcare, computer graphics, game processing, and artificial intelligence are the biggest users of the C programming language.</p>
<p dir="ltr">Other than UNIX, it is also used in system applications of Windows and many embedded software.
