You get many error/warning messages. That's why headers always have a frame like this:
#ifndef HEADERNAME
#define HEADERNAME
... actual content ...
#endif
This way multiple inclusions won't cause any trouble.
Java does not require header files like C/C++.
There is no system header called share.h, but if there were, it would be: #include <share.h>
No. You can't use namespace std even if you include stdio.h. At the very least you must include stddef.h before you can use namespace std.
There is a 'getch' in 'conio.h' which has nothing to do with 'iostream'.
We only include the headers we actually use. It would be impractical to include every single header in every single program.
# include <stdio.h> # include <conio.h> # include <stdlib.h> # include <string.h>
Header files are used to have declarations. It is simple to include a single header file than writing all the needed functions prototypes.
You need to #include the header file that contains the missing function's declaration.
strcat if u wnt to use strcat then include string.h header file

A haeder is a text-file, meant to include (#include) into a source-file. Usually it contains variable and function declarations, constants, type-definitions, documentation.
No explicit limit, you can use so many header files as you want.
Yes.
it is sqrt in header math.h
To include a header or footer in a publication you will have to view the .?
There is no system header called share.h, but if there were, it would be: #include <share.h>
The source file must include the header file. Beyond that we can only guess at the problem without seeing the content of the source and header files. Do not post the files here. Such questions are better handled by the many C programming forums available elsewhere on the Internet.
