Header files allow a C source file to use functions in other C files or library files. The linker ignores the fact that these functions are not defined in C source code, assuming that they'll be defined somewhere else.
"stdlib" offers prototypes for many functions that deal with string conversion, pseudo-random number generation, dynamic memory management, program environment, integer math and other functions not available within the C standard.
See the related link below for a list of function prototypes offered by stdlib.h.
There is no system header called share.h, but if there were, it would be: #include <share.h>
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 use of header files is to add functionality. Header files are basically saying put code in that header file here so you don't have to type that many lines of code.
The std::pow() function can be found in the <cmath> header.
Yes,we can compile our program without header file without any error,but we can not use any predefine functions like printf,scanf.
It contains useful function-prototypes.
stdbool header file use for a new data type that is boolean value
Some of them: stdio, stdlib, stddef, string, stdarg, signal.
You can include it into your source.
There is no system header called share.h, but if there were, it would be: #include <share.h>
Use the help (F1).
Use a text-editor.

Classes and structures can be put in a header file the same way you would use them in a main program; the only difference is that they are placed in a separate file, called a header file. Then, after creating a new file, include that new file with the definition by the use of the preprocessor #include statement.

The header file of graphics in TurboC is graphics.h
The std::pow() function can be found in the <cmath> header.
