Editing Hex with C ++

Question

Suppose I want to change something in the address 000F5344 of an executable file. How should I do it?

Answer 1

@Pablo Santa Cruz offers a great way, but in C. If you prefer pure C ++, here's how:

• Open file: fstream :: open (do not forget to use the binary flag)
• Set the position of the put pointer: fstream :: seekp
• Write the data to the pointer position: fstream :: put
• Close file: fstream :: close

This is by no means better than version C.

Answer 2

The following solution consists of four steps:

• ( fopen).
• (offset) ( fseek).
• ( fwrite).
• ( fclose).
