inputing keys

Code:

#include <curses.h>

int main(int argc, char *argv[])
{
  initscr();
  raw();

  int a = getch();

  printf(%d, a);

  getch();

  endwin();
  return 0;
}

i need to input a key and print not the char but the hex or octal code so that i can determine the code for the esc key.

i want my getch() command to respond to the esc key, but it does not seem to when i use \1B

Code:

printf("Oct: %o Hex: %x\n",a,a);

Or, since this is the C++ board:

Code:

#include <iostream>
#include <iomanip>

...

std::cout << "Oct: " << std::oct << a << " Hex: " << std::hex << a << std::endl;
