g Create a file named functions. cpp, inside which you need to: - Develop a function that performs bubble sort on an int array. - Develop a function that uses call-by-reference to swap two ints. - Develop a function that uses std::swap to swap two strings. - Develop a main function to call above functions.

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).
