We know that we use many headder file such as
stdio.h, dos.h, conio.h, stdlib.h, graphics.h, iostream.h etc.
So how can you say that there is no need of this extension ?

We can define fact.c, filename.c in header file.
So, if you mention filename.c, it will read the entire file.

@ALL
Is is necessary that a header files should have ".h" ?
Answer is NO.
Because the header files can have any extension but it should be included with in C program with same extension.
Let me explain what I did to check this...
In Turbo C directory
C:\Turbo>copy stdio.h stdio.hdr
C:\Turbo>copy conio.h conio.exe
Then I used the line following line to include the header file.
#include<stdio.hdr>
#include<conio.exe>
void main()
{
printf("Welcome to IndiaBIX.com !");
getch();
}
The output : Welcome to IndiaBIX.com !

Without .h extension it is not possible to include the function like printf, scanf etc.

#include"filename.c".
"this is also a header file".
In a extern concept, many different files can use same variable.
By using include the whole file.
That's all about it.
Thanks.
