May I ask why you gave a B grade ? That usually means that something was missing in the answer and/or that something is still unclear. If so, please feel free to ask for clarification where needed.

I have written a lex grammar which takes the input from stdin and output to stdout. But I want to pass the input as char[] (eg: char *input_buffer, int input_length) and get output as char[] (eg: char *output_buffer, int output_length). Anyone please help me out this.

How to mention in the lex grammar to give the input as a char[] and get output as char[]?

A programming language is a formal constructed language designed to communicate instructions to a machine, particularly a computer. Thousands of different programming languages have been created, mainly in the computer field, and many more still are being created every year. The description of a programming language is usually split into the two components of syntax (form) and semantics (meaning). Some languages are defined by a specification document (for example, the C programming language is specified by an ISO Standard), while other languages (such as Perl) have a dominant implementation that is treated as a reference. Some languages have both, with the basic language defined by a standard and extensions taken from the dominant implementation being common.

C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, so it has found lasting use in applications that had formerly been coded in assembly language, including operating systems as well as various application software for computers ranging from supercomputers to embedded systems. It is distinct from C++ (which has its roots in C) and C#, and many later languages have borrowed directly or indirectly from C.
