Write an EBNF rule that describes the do while statement of Java or C++. Write the recursive-descent subprogram in Java or C++ for this rule. Please test your code by parsing for the following example. Please submit your source code and a screen shot of the parsing for the following example. do { sum= sum+1; } while (sum<10)

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).
