What is the difference between "stdio.h" & <stdio.h> in c

Answer 1

Okay! When write

#include<stdio.h>

You tell the compiler to search for the file ‘stdio.h’ in the standard library folders only .

but when you write

#include”stdio.h”

You mean that search the file ‘stdio.h’ in the standard library functions as well as in the current folder where you are working .

Now suppose you have stored this file any other place like c/documents/stdio.h then you just need to write the correct path in them like

#include”c/documents/stdio.h”

and the compiler will include these files into your current program. In such situations

#include<c/documents/stdio.h>

WILL NOT WORK !!

Hope this helps!

Answer 2

The significant difference is that <stdio.h> tries to find in standard C library locations,as of "stdio.h" searches in both the current directory as well as in library locations.

Generally, we would use <...> for standard C libraries and "..." for libraries that you write and are located in the current directory.
