Answer 1

learn (this might help you)

# is called pre processor directives.
note.

pre-processor run those statement start with #.

actually in c.
when we complie the code.
5 process run at a single commands.
i.e
1.pre processor.
2.complier
3.Assembler
4.Limker
5.loader.

so now you know # statement execution by pre processor.

so what does # do.
it indicate the pre processor,
that before compile run these # statement..

now back to your question
#include<stdio.h>
# statement come(pre processor)
include(include code)
stdio.h

so pre processor find the stdio.h and take the code.
and merge with our code.

i.e we cant get error cant find printf()
or and other function of stdio.h
