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
Header files are not much different from usual cpp files. There are basically two different things. It's file extension: you need to choose "header file" when you create it or save as .h file. Second is header files do not have main() function. When you are done with you header file do not forger to include it in your project by writing preprocessor directive:#include "your_header_file.h"
stdbool header file use for a new data type that is boolean value
The FILE type is declared in stdio.h.
Not possible. Always make backup copies.
There is no system header called share.h, but if there were, it would be: #include <share.h>
Never, and the reason is that header files are not meant to be executed.
Yes, it is a plain text file.
string.h
Look for typedef in it, but I don't think you will find any.
Any file can be called a header. Whenever someone uses #include , it's the same as copy/pasting that file in that spot. Typically though, they call it a header if it's included at the beginning of your source.
