Consider an ISP and assume onlythese organizations are under that ISP: Organization 0 with this network prefix: 200.23.16.0/23
Organization 1 with this network prefix: 200.23.18.0/23
Organization 2 with this network prefix: 199.31.0.0/16

The ISP needs to aggregate as much as it can the above prefixes before it advertises the prefixes resulting from the aggregation. If a prefix cannot be aggregated with any other one, the prefix resulting from the aggregation is the prefix itself. What are the resulting prefixes advertised by the ISP?

Consider the following code snippet: #ifndef cashregister_h#define cashregister_hconst double max_balance = 6000000.0; class cashregister{public: cashregister(); cashregister(double new_balance); void set_balance(double new_balance); double get_balance() const; private: double balance[12]; }; double get_monthly_balance(cashregister bk, int month); #endifwhich of the following is correct? a)the header file is correct as given.b)the definition of max_balance should be removed since header files should not contain constants.c)the definition of cashregister should be removed since header files should not contain class definitions.d)the body of the get_monthly_balance function should be added to the header file.
