Answer / bhaskar.mantrala

why because when we compile a program all input and output
statements will be replaced by thier own codes present in
the directives...so all these things would be done by
preprocessor(pre processing) (#).....

Answer / ashu_deepu

because there are codes which we use in the main program

need to be defined before their use.
or we can say we do so to have the prototype declaration
before their use.
eg.printf,scanf etc.

preprocessor include the header file
like stdio,conio etc.
