How to edit a binary file's hex value using C?

I think this is best explained with a specific example. Here are the first 32 bytes of an executable file as shown in Visual Studio's hex editor.

Well the first thing would probably be to understand the conversions. Hex to decimal probably isn't as important (unless of course you need to change the value from a decimal first, but that's a simple conversion formula), but hex to binary will be important seeing as each hex character (0-9,A-F) corresponds to a specific binary output.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
