Assume the existence of a class arr with two (public) data members: a pointer to integer named arr_ptr, and an integer variable named length that will contain the number of elements in the array. assume the variable a has been declared to be of type arr, an array has been allocated and assigned to arr_ptr, and length has been assigned the proper value (i. e., the number of elements in the array). write the code to add 1 to each element of the array. submit

Assume the existence of a bankaccount class. define a derived class, savingsaccount that contains two instance variables: the first a double, named interestrate, and the second an integer named interesttype. the value of the interesttype variable can be 1 for simple interest and 2 for compound interest. there is also a constructor that accepts two parameters: a double that is used to initialize the interestrate variable, and a string that you may assume will contain either "simple", or "compound", and which should be used to initialize the interesttype variable appropriately. there should also be a pair of functions getinterestrate and getinteresttype that return the values of the corresponding data members (as double and int respectively).
