C++类型常量：

cout << "CHAR_BIT = " << CHAR_BIT << endl;
cout << "CHAR_MAX = " << CHAR_MAX << endl;
cout << "CHAR_MIN = " << CHAR_MIN << endl;
cout << "SCHAR_MAX = " << SCHAR_MAX << endl;
cout << "SCHAR_MIN = " << SCHAR_MIN << endl;
cout << "UCHAR_MAX = " << UCHAR_MAX << endl;
cout << "SHRT_MAX = " << SHRT_MAX << endl;
cout << "SHRT_MIN = " << SHRT_MIN << endl;
cout << "USHRT_MAX = " << USHRT_MAX << endl;
cout << "INT_MAX = " << INT_MAX << endl;
cout << "INT_MIN = " << INT_MIN << endl;
cout << "UINT_MAX = " << UINT_MAX << endl;
cout << "LONG_MAX = " << LONG_MAX << endl;
cout << "LONG_MIN = " << LONG_MIN << endl;
cout << "ULONG_MAX = " << ULONG_MAX << endl;
cout << "LLONG_MAX = " << LLONG_MAX << endl;
cout << "LLONG_MIN = " << LLONG_MIN << endl;
cout << "ULLONG_MAX = " << ULLONG_MAX << endl;
