// Program:  show_in_hex
// Author:  B. Massingill
// Purpose:  display internal representation of an integer.
// Input:  an integer n, from standard input (program will prompt for it).
// Output:  internal hexadecimal representation of n.

#include <iostream.h>
#include <iomanip.h>		// has setw(), setfill()
#include <stdlib.h>		// has EXIT_SUCCESS

int main(void)
{
  int n;

  // prompt for and read an integer.
  cout << "Enter an integer:\n";
  cin >> n;

  // echo it back in regular decimal format.
  cout << "You entered " << n << endl;

  // now print it in hexadecimal format, exactly 8 digits
  cout << "The computer's representation is "
       << setw(8) << setfill('0') << hex << n << endl;
