For a Button object named btnCalories, write the click event handler to implement the following requirements to calculate the number of calories burned in a run: a. Declare variables named strMilesRan, decCaloriesConsumed, and decMilesRan.
b. Declare a constant named and assign it the value 700 (assume you burn 700 calories for every mile you run).
c. Allow the user to enter the number of miles she ran today.
d. Convert the number of miles to a Decimal data type.
e. Calculate the number of calories the user burned during her run.
f. Display the result rounded to zero decimal places in a label named lblCaloriesBurned.

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).
