C Programming Language

C language is a computing language that was first developed between 1969 and 1973 at AT&T Bell Labs. It is one of the most widely used languages of all times and is thus used by compilers in computer architecture and operating systems.



Many other languages have been derived by C language, some examples of these are D, Go, Rust, Java, JavaScript, Python, Objective-C, PHP, Perl, Verilog and the like. Most of these languages are syntactically similar to C in their control structures, but they can possess their own data types, models and semantics. Some characteristics of the language include, there is a fixed amount of keywords which is thirty two used for instance for, if, then, else, auto, double, default, continue, do while, static, extern, switch and many more. Also there are a large number of arithmetic operators such as +,-, =,*, , & etc. A major function is that a pre-processor processes the file functions such as compilation, and the inclusion of the source file for the programming.


Also complex functions such as string manipulation, internal operation, and mathematical operations are designated to the library functions. The character set of the language include uppercase and lowercase letters, decimal letters, other characters are also available such as space, horizontal tab, vertical tab, form feed and new line. The language also supports the use of pointers such as data type pointers and null pointers.


A data type pointer might point to arithmetic or a string data type. Whereas a string pointer points to a string type. These can be checked by the compiler at run time. A null pointer on the other hand does not point to any specific object. It can be de-referenced since there is no valid location to point at. There are also void pointers that do not contain any type of value and can therefore be used as generic data types at the time of program segmentation. Then another type is the dangling pointers which keep on switching their values throughout the program code as they may not have been initialized at the very beginning of the program code, such pointers are also called wild pointers. Another feature of the language is the use of arrays, C does not provide the user with multi-dimensional arrays, array types that are fixed, static size and specified at compile time. Also the language uses libraries as its primary feature of extension. Each library entails within itself a set of archive functions and files.



Lastly, one of the most important features of any programming language is its allocation of memory. It provides three different ways for the allocation of memory namely dynamic memory allocation, static memory allocation and automatic memory allocation. Static type is when the object is operated upon at compile time. Automatic, when objects are stored in stacks and can be used and reused as and when required. Dynamic is used when blocks of arbitrary size are used at run time using certain library functions. Thus the language is definitely worth a try for programming experts and lovers of this arena!
