1. Have your employers and have you ever used a hex editor? You can get one for free by using Google. xvi32 is the name of one of them, and there's countless of quality editors out there. Both you and your employers should try a few of them out and see what a hex editor is like.
2. Have you ever programmed before?
3. Have you programmed in C before?
4. Do you know how to read large files? Do you know how to manage large buffers in memory? How much experience with data structures and algorithms do you have?
5. If you are still required to program a hex editor, you need details. Does it intuitively make sense that to write a program, you need details about what to write? Do you understand it is impossible to create something when you have absolutely no detail about what to create?
6. Did you by any chance misrepresent your skillset to your employers? By your questions, and grammatical capabilities, It seems like you know near to nothing about C, or programming for that matter.
