In 1971, Ritchie started to improve B, to utilise the features of the more-powerful PDP-11. A significant addition was a character type. He called this New B.Unix kernel, and his requirements shaped the direction of the language development.int and char. Pointers, the ability to generate pointers to other types, arrays of all types, and types to be returned from functions were all also added. Arrays within expressions became pointers. A new compiler was written, and the language was renamed C.

Since K&R function declarations did not include any information about function arguments, function parameter type checks were not performed, although some compilers would issue a warning message if a local function was called with the wrong number of arguments, or if multiple calls to an external function used different numbers or types of arguments. Separate tools such as Unix"s lint utility were developed that (among other things) could check for consistency of function use across multiple source files.

A number of tools have been developed to help C programmers find and fix statements with undefined behavior or possibly erroneous expressions, with greater rigor than that provided by the compiler. The tool lint was the first such, leading to many others.

Automated source code checking and auditing are beneficial in any language, and for C many such tools exist, such as Lint. A common practice is to use Lint to detect questionable code when a program is first written. Once a program passes Lint, it is then compiled using the C compiler. Also, many compilers can optionally warn about syntactically valid constructs that are likely to actually be errors. MISRA C is a proprietary set of guidelines to avoid such questionable code, developed for embedded systems.

Tools such as Purify or Valgrind and linking with libraries containing special versions of the memory allocation functions can help uncover runtime errors in memory usage.

Historically, C was sometimes used for web development using the Common Gateway Interface (CGI) as a "gateway" for information between the web application, the server, and the browser.interpreted languages because of its speed, stability, and near-universal availability.web development tools exist.

There are tools that can mitigate against some of these drawbacks. Contemporary C compilers include checks which may generate warnings to help identify many potential bugs.

C is a powerful general-purpose programming language. It can be used to develop software like operating systems, databases, compilers, and so on. C programming is an excellent language to learn to program for beginners.

This was a key innovation at that time. Up to this point, we were in the early mainframe era, where massive, powerful, and extremely costly computers used to take up entire rooms.

At the beginning of the project, Ken Thompson could not program on the DEC PDP-7 computer. DEC PDP-7 programs had to be compiled and translated on the more powerful GE 635 mainframe and then the output was physically transferred to the PDP-7 by paper tape.

While working on MULTICS, they used high level programming languages, like PL/I in the beginning and later BCPL. Programmers had gotten used to using high level languages for writing operating system kind of software, utilities, and tools because of the advantages they offered (they were relatively easy to use and understand).

B had many of the features of BCPL but it was a smaller language, with a less verbose syntax and simpler style. It was still slow and not powerful enough to support Unix utilities, however, and couldn"t take advantage of the powerful features of the PDP-11.

Dennis Ritchie decided to improve upon these two previous languages, BCPL and B. He took features and characteristics from each and added additional concepts. He created a more powerful language – C – just as powerful and efficient as Assembly. This new language overcame the limitations of its predecessors and could use the power of the machine in an effective way.

This increase in popularity came from not only the power C gave to the machine but also to the programmer. It also helped that the Unix operating system was gaining the same popularity at an even faster rate.

It owes its popularity to the rise and success of Unix, but nowadays it has gone far beyond just being the "native" language of Unix. It now powers most, if not all, of the world"s servers and systems.

C does not hide the complexity with which a machine operates. It gives you a lot of power and flexibility, like the ability to manually allocate, manipulate, and write directly to memory.

There is a lot of C code in the devices, products, and tools that billions of us use in our everyday lives. This code powers everything from the world"s supercomputers to the smallest gadgets.

Your fitness tracker and smart watch? Powered by C. The GPS tracking system in your car, and even traffic light controllers? You guessed it – C. And there are many examples of embedded systems used in the industrial, medical, robotics, and automobile industries that run on C code.

The Microsoft Windows kernel is scripted mostly in C, and so is the Linux kernel. Most supercomputers are powered by Linux, and so are most Internet servers. This means that C powers a large section of the Internet.

Linux also powers Android devices, so C code not only makes supercomputers and personal computers work, but smartphones too. Even OSX is coded to some extent in C, which makes Mac computers run on C, too.

Many browsers and their extensions are built with C, like Google Chromium and the Google file system. Developers also use C often in database design (MySql and Oracle are two of the most popular database systems built in C), and it powers advanced graphics in many computer games.

If you"re using MacOS and have not installed the command line developer tools, you will get a dialog box pop up asking you to install them – so if you see that, go ahead and do so.

Once you have those installed, open a new terminal session and re-type the gcc --version command. If you have already installed the command line tools, you should get the output below:
