When the program below is compiled and executed, it produces the
following output:

min value is -./,),(-*,(
max value is 2147483647

When the two lines containing cout are commented out and the printf
line is uncommented, the following output is produced:

e is -2147483648, f is 2147483647

#include <stream.h>

main()
{
  int e;
  int f;

  e = 1;

  /* make larger */
  while (e > 0)
    {
      e <<= 1;
      f = e - 1;
    }
  cout << "min value is " << (int)e << '\n';
  cout << "max value is " << (int)f << '\n';
/*  printf("e is %d, f is %d\n", e, f); */
