I found the problem. Xcode C++ treats 'long int' as a 32 bit number.
This code:
cout << "sizeof(long) = " << sizeof(long) << endl;
cout << "sizeof(int) = " << sizeof(int) << endl;
cout << "sizeof(long long) = " << sizeof(long long) << endl;
cout << "sizeof(long int) = " << sizeof(long int) << endl;
gives the output:
sizeof(long) = 4
sizeof(int) = 4
sizeof(long long) = 8
sizeof(long int) = 4
So long is 4 bytes or 32 bits, int is 32 bits, long long is 64 bits,
but long int is only 32 bits! What a terrible trap for any programmer!
