An array of int named a that contains exactly five elements has already been declared and initialized. in addition, an int variable j has also been declared and initialized to a value somewhere between 0 and 3. write a single statement that assigns a new value to the element of the array indexed by j. this new value should be equal to twice the value stored in the next element of the array (i. e. the element after the element indexed by j). do not modify any other elements of the array!

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.
