Write an application that will accept two decimal values in textboxes and calculate the sum and the quotient.When button Calculate1 is clicked • The two numbers are stored in variables • Call one method Calculate to perform calculations • Display results on labels Methods.Method Calculator uses call-by-value and call-by-reference(Ref) parameters to return thevalues.

Create a program that solves for the sum of all positive integers starting from 1 until the number given by the user. Use a recursive fuction to address this problem. Assume that the user will always enter a positive number.

Example:

Enter number: 100
Sum of integers from 1 to 100 is 5050.

Write an application that will accept two decimal values in textboxes and calculate the sum, the difference, the product, and the quotient .Must have two buttons.
When button Calculate1 is clicked
• The two numbers are stored in variables
• Call four methods Add,Subtract, Multiply and Divide to perform the calculations
• Display the results on labels
When button Calculate2 is clicked
• The two numbers are stored in variables
• Call one method Calculate to perform calculations
• Display results on labels

Methods Add, Subtract, Multiply and Divide use call-by-value parameters and return a double value
Method Calculator uses call-by-value and call-by-reference(Ref) parameters to return thevalues.

A phone call cost 10 cents per minute. Write a program that generates two random numbers for hours and minutes and calculate the cost of the call. Look at exercise 12.6page 224 that shows how to create a random number.(Note: there is no input from the user).
Button Make a call
When this button is clicked, two random numbers are generated. A call cannot be more than 5 hours long. The generated hours and minutes are displayed on labels. Calculate the cost of the call in minutes and display it on a label.
The use of correct types, formatting and constants will earn you marks.
