Can anyone explain to me why PROG1 works, but PROG2 dies?  (Both work
fine with Visual C++.)

// PROG1.CPP
#include <iostream.h>

void  PrList (int stopval)
{       int x = 1;
        while (1)
        {       if (x >= stopval) throw x;
                cout << x++ << endl;
        }
}

int  main (void)
{       try {  PrList (10);  }
        catch (int n) {  cout << "Exception at " << n << endl;  }
        return 0;
}


// PROG2.CPP
#include <iostream.h>

void  PrList (int stopval)
{       int x = 1;
        while (1)
        {       if (x >= stopval) throw "Out of bounds";
                cout << x++ << endl;
        }
}

int  main (void)
{       try {  PrList (10);  }
        catch (char *msg) {  cout << msg << endl;  }
        return 0;
}


Thanks,
