Below is the hex dump function, but what I need is dec dump.

C

void DumpBytes(unsigned char* inputBytes,int inputBytesLength,char* ouputString)
{
    unsigned char const Hex[] = "01234567890abcdef";
    for (int i = 0; i < inputBytesLength; i++)
    {
        unsigned char binByte = inputBytes[i];
        ouputString[2*i] = (Hex[(binByte & 0xf0) >> 4]);
        ouputString[2*i + 1] = (Hex[binByte & 0x0f]);
    }
}

How do I dump bytes to decimal string instead of heximal string?

Thanks in advance!

A C++ answer, safer on output size potential problem:

#include <sstream>
#include <iterator>
std::string DumpBytes(unsigned char* inputBytes, int inputBytesLength)
{
   std::ostringstream oss;
   std::copy_n(inputBytes, inputBytesLength, std::ostream_iterator<int>(oss, " "));
   return oss.str();
}

cheers,

It's quite trivial: use the sprintf and strcat functions.

C++

void DumpBytes(unsigned char* inputBytes, int inputBytesLength, char* ouputString)
{
   char tmp[5]; // 0-255 + whitespace + terminating NULL -> max 5 char

   outputString[0] = '\0';
   for(int i = 0; i < inputBytesLength; i++)
   {
      sprintf_s(tmp, "%u ", inputBytes[i]);
      strcat(outputString, tmp);
   }
}
