hex dump

how do i hex dump a binary file i created using c++

thanks

Dump I would assume you mean to screen? If so, you need to write custom code that reads in the data file into a buffer then displays it to screen, something similar to the following code snippet:

Code:

---

static void dumpMemory_HexAscii(const void *pvObject, u4 u4ObjectSize, std::ostream& os)
    {
      u1 u1X;
      char cX;
      u4 uX;
      int iBase = 0;
      const int iiPerLine = 16;

      for(;;iBase++)
      {
        //a_Hex
        for (uX = 0; uX < iiPerLine; uX++)
        {
          if (iBase * iiPerLine + uX >= u4ObjectSize)
            break;
   
          u1X = *((unsigned char *)pvObject + iBase * iiPerLine + uX);
          os << (u1X < 16 ? "0" : "") << std::hex << (int)u1X << " ";
        }
        os << ": ";
     
        //a_ASCII
        for (uX = 0; uX < iiPerLine; uX++)
        {
          if (iBase * iiPerLine + uX >= u4ObjectSize)
            break;
   
          cX = *((char *)pvObject + iBase * iiPerLine + uX);
          os << (isalnum((u1)cX) ? cX : '.');
        }
        os << std::endl;

        if (iBase * iiPerLine + uX >= u4ObjectSize)
          break;
      }
    }

type info:
typedef unsigned char u1;
typedef unsigned short u2;
typedef unsigned long u4;
