C focuses on making systems and applications run smoothly. It’s so influential that it’s the grandpa of other cool languages like C++ and Java. Some folks say it could be simpler to learn, but hey, it’s still going strong after all these years.

History of C language

The story of the C programming language begins in the early 1970s at Bell Laboratories, where Ken Thompson and Dennis Ritchie teamed up to create it. Back then, writing programs for the UNIX operating system was a real headache because everything had to be done in assembly language, which was tough to work with

Thompson initially developed a language called B, but it needed improvements to keep up with the evolving computer hardware. That’s when C came into the picture. By 1973, C had become mature enough to rewrite the entire UNIX operating system.

But here’s the catch: before people outside of Bell Labs could use C effectively, they needed to learn how to use it. That’s where Brian Kernighan and Dennis Ritchie’s book, “The C Programming Language,” came in handy. It became the go-to guide for C programming and is still widely used today.

As the 1980s rolled in, developers wanted to standardize the language to avoid confusion. The American National Standards Institute (ANSI) and the International Organization for Standardization (ISO) stepped in to create standards for C.

But even with these standards, using C for large software programs was still a bit tricky. So, programmers started creating their own compilers and even new languages, like C++ and Java, which borrowed heavily from C. These new languages made coding complex tasks much easier, especially as computers became more powerful.

How Can C Be Used in Web Development?

C can be used in web development primarily through CGI programming and writing custom web servers. CGI, or Common Gateway Interface, allows C programs to interact with web servers, generating dynamic web content. By writing a C program that outputs HTML and configuring the server to execute this program as a CGI script, developers can create web pages on the fly. Additionally, C is often used to build high-performance web servers. Popular web servers like Nginx and Apache are written in C, leveraging its efficiency and control over system resources. While using C for web development is less common and more complex than using languages like PHP or JavaScript, its powerful performance capabilities make it suitable for certain high-demand scenarios.

So there you have it – a crash course on why C is such a big deal in the world of programming. Whether you’re writing code for an operating system, creating mind-blowing special effects, or tinkering with gadgets, chances are you’ll run into C along the way.

How C Programming Language Works?

C is a compiled language. That means we take our written instructions (called source files), which are like our to-do lists for the computer, and turn them into special files (object files) that the computer can understand. It’s like translating our to-do list into a language the computer can read, so it knows what to do.

Writing Code

So, when we want to make a program in C, we start by writing out our instructions. It’s like giving the computer a to-do list, but we write it in a special language called C. We just need a simple text editor, like the one you use to write emails, to type out our instructions.

Making it Computer-Friendly

Now, computers don’t understand human language, so we have to translate our C instructions into something the computer can understand. We use a special tool called a compiler to do this. It’s like having a super smart friend who can translate our C into a language the computer speaks.

Fixing Up the Details:

Sometimes, our instructions have special parts that need a little extra attention. That’s where the preprocessor comes in. It goes through our instructions and makes sure everything is ready for the computer to understand. Think of it like tidying up before guests come over!

Putting the Pieces Together:

Now that our instructions are all translated, we need to make sure they fit together properly. We use another tool called a linker for this. It takes all the translated parts of our program and puts them together into one neat package, kind of like assembling a puzzle.

Getting Ready to Go:

Before our program can start doing its thing, it needs to get all set up in the computer’s memory. We have a special friend called a loader who helps with this. The loader takes our program and gets it all ready to run on the computer, like setting up a stage for a play.

And there you have it! With these steps, we can take our ideas and turn them into programs that the computer can understand and follow. It’s like telling the computer exactly what we want it to do, but in a language it can understand. Easily.
