features of c processor

As the C preprocessor does not havefeatures of some other preprocessors, such as recursive macros, selective expansion according to quoting, and string evaluation in conditionals, it is very limited in comparison to a more general macro processor such as m4.

The C preprocessor is a macro processor that is used automatically by the C compiler to transform your program before actual compilation. It is called a macro processor because it allows you to define macros.

A function is a group of statements that together perform a task. Every C program has at least one function, which is main(), and all the most trivial programs can define additional functions.
reason is reusability. Once a function is defined, it can be used over and over and over again. ... Another aspect of reusability is that a single function can be used in several different (and separate) programs.
By implementing functions and procedures in his program, the programmer reduces coding time and debugging time, thereby reducing the overall development time. Save programming time by using procedures and functions.
