A header file is used in some languages to declare functions that will be used but are not yet defined in the current source code. This is primarily used by C and C++, and usually for library functions and user-defined functions that are stored in separate files and folders than the main source code file.
Yes (but usually it is a bad idea).

You need to #include the header file that contains the missing function's declaration.
Header files are used to have declarations. It is simple to include a single header file than writing all the needed functions prototypes.
strcat if u wnt to use strcat then include string.h header file
Windows h is a header file for the programming language C++. If one were looking to learn about this specific header file there are forums that exist specifically for this topic on the C plus plus help page.
Header bios.h doesn't have a 'key pressing code'.
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.
Header file is a file which is meant to be included into another file during compilation. Examples: string.h, stdio.h, inttypes.h. Header pointer is a pointer to an object called header (for example header of a linked list).
The header file of graphics in TurboC is graphics.h
conio.h is a library function which is predefined in the header file and 'clrscr();','getch();' and many other functions come under this.
