I've been working on this program all day and I'm so lost please help! I need to have a class that uses a 40 element array that has predicate function IsEqual, IsGreaterThan, etc and with member functions input, output, add, subtract. Is there anyway I can make this code smaller?
class HugeInteger
{
public:
HugeInteger();
void input();
void const output();
void add(const HugeInteger&);
void subtract(const HugeInteger&);
bool isEqualTo(const HugeInteger&);
bool isNotEqualTo(const HugeInteger&);
bool isLessThan(const HugeInteger&);
bool isLessThanOrEqualTo(const HugeInteger&);
bool isGreaterThan(const HugeInteger &);
bool isGreaterThanOrequalTo(const HugeInteger&);
bool isZero;
~HugeInteger();

int const ArraySize;
int const [40];
