Question

I have an input of char *str = "13 00 0A 1B CA 00";

I need an output as BYTE bytes[] = { 0x13, 0x00, 0x0A, 0x1B, 0xCA, 0x00 };

can somebody help with a solution?

You will need to parse out each of the two characters and then convert them into BYTE. This isn’t fairly difficult to do.

std::stringstream converter;
std::istringstream ss( "13 00 0A 1B CA 00" );
std::vector<BYTE> bytes;

std::string word;
while( ss >> word )
{
    BYTE temp;
    converter << std::hex << word;
    converter >> temp;
    bytes.push_back( temp );
}
