The body of an if block is only executed if the condition is true. TASK Modify the script so that the plotting code on lines 4-7 are executed only when doPlot is 1. Hint Modify the if statement as shown if doPlot %% Plotting code; end Test Results: Incorrect! Is there no plot when when doPlot is 0? Is there a plot when doPlot is 1? Is the plot correct with doPlot is 1?

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).
