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.
C programs do not require header files. If you want a C program without header files, you can simply not create them. However, you may or may not be able to include your non-header file source files.
Use a text-editor.
Create the header file as a .h file in the same way you create a source file, .c and place it in the same directory as the .c files. To incorporate it, use the... #include "my_header_file.h" ... directive. Note that there are double quotes instead of greater/less signs. This tells the compiler to look first in the source directory.

Look for typedef in it, but I don't think you will find any.

The header file for random functions ( like rand(), srand() ) is stdlib.h in C and cstdlib in C++.
For start: they are header files.
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.
For example: int main (void) { return 0; }
