presenting a string as a byte

Hi

I have the following string :

"1F"

I need to present it as a BYTE

so if I have : BYTE array[2]

then -> array[0] = 0x1F

How can it be done?

Thank u

Code:

---

#include <iomanip>
#include <iostream>
#include <string>
using namespace std;

int main(int argc, char *argv[])
{
  const char* hexNum = "1F";
  int actualByte = 0;

  // one method
  istringstream is(hexNum); 
  is >> hex >> actualByte;
  cout << hex << actualByte << endl;

  // another method
  sscanf(hexNum, "%02x", &actualByte);
  cout << hex << actualByte << endl;

  return (0);
}
