This approach may be used for portability or convenience; by using C as an intermediate language, additional machine-specific code generators are not necessary. : and the comma operator). Instead, he created a cut-down version of the recently developed BCPL systems programming language. C programming language is a MUST for students and working professionals to become a great Software Engineer specially when they are working in Software Development Domain. Preprocessor was introduced around 1973 at the urging of Alan Snyder and also in recognition of the usefulness of the file-inclusion mechanisms available in BCPL and PL/I. Libraries are often written in C because C compilers generate efficient object code; programmers then create interfaces to the library so that the routines can be used from higher-level languages like Java, Perl, and Python.[28]. (Static allocation that is too large is usually detected by the linker or loader, before the program can even begin execution.). The closing curly brace indicates the end of the code for the main function. For example, the conditional expression if (a == b + 1) might mistakenly be written as if (a = b + 1), which will be evaluated as true if a is not zero after the assignment. There are also derived types including arrays, pointers, records (struct), and unions (union). In this call, the printf function is passed (provided with) a single argument, the address of the first character in the string literal "hello, world\n". Null pointer values are useful for indicating special cases such as no "next" pointer in the final node of a linked list, or as an error indication from functions returning pointers.

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. In conditional contexts, null pointer values evaluate to false, while all other pointer values evaluate to true. [33] Taking advantage of the compiler's knowledge of the pointer type, the address that x + i points to is not the base address (pointed to by x) incremented by i bytes, but rather is defined to be the base address incremented by i multiplied by the size of an element that x points to. Some standard headers do define more convenient synonyms for underscored identifiers. There are also compilers, libraries, and operating system level mechanisms for performing actions that are not a standard part of C, such as bounds checking for arrays, detection of buffer overflow, serialization, dynamic memory tracking, and automatic garbage collection. The next line indicates that a function named main is being defined.
Pointers to functions are useful for passing functions as arguments to higher-order functions (such as qsort or bsearch) or as callbacks to be invoked by event handlers.[28]. Most of the state-of-the-art software have been implemented using C. Today's most popular Linux OS and RDBMS MySQL have been written in C. Just to give you a little excitement about C programming, I'm going to give you a small conventional C Programming Hello World program, You can try it using Demo link.
