[Solved] SOLVED:Big number Solution

In this task, you are going to write a C++ class to handle very large numbers. The following prototype is given.`cppclass LLONG{public:LLONG();LLONG(int);LLONG(const LLONG &);~LLONG();void add(const LLONG &);void subtract(const LLONG &);void multiply(const LLONG &);void divide(const LLONG &);void mod(const LLONG &);std::ostream & output (std::ostream &);int compare(const LLONG &);// return 0 for equal, 1 for , -1 for <private: // your design here // you are not allowed to use string here};`
