Design, code, and test a program that includes a function of type double called merganser that accepts two double arguments (you must write the merganser function). When called, your function will return the first argument divided by the second argument. Make sure your function includes a decision statement so that it can't divide by 0--if the caller attempts to divide by 0 the function should return a value of -1.0. Your program should call merganser then display the value returned by the function. Test your function thoroughly then submit output using the arguments 28.2 and 11.7. Remember that a structured function must have have only one return statement.
