Beginner in C#. I need the code for this GUI provided. We need to code functions and call them as well. Please don't use Arrays as we have not covered that and please leave comments helping me understand. Please refer to the following:

Need to write a program that calculates the present value for a future investment goal, future value for an investment made today, or monthly payment for a fixed-rate loan.

The formula for each of these values are listed below;

FV= future value PV = present value MP= Monthly Loan Payment IR = yearly or monthly interest rate as a decimal Terms = number of years or months, NP = number of monthly payments LA = loan amount

Remember to convert the interest rate to a decimal percent (IR * .01 or IR/100) and for the monthly payment also convert the interest rate to a monthly value (IR/12 * .01 or IR/12/100)

FV = PV * (1 + IR) ^ Terms Note: Terms = Years

PV = FV / (1 + IR) ^ Terms Note: Terms = Years

MP = LA * (IR*( 1+IR) ^ NP) / ((1 + IR) ^ NP -1) Note: NP = Years * 12

Calculations must be done with a function. Each function must use an argument list.

Caluclate Button- create a function to validate the user entry. If valid perform a calculation function, format result as currency.

Clear button- should clear all data pn the form (entry and result textboxes/labels), focus should be placed in the present value textbox.

Summary button- report the following in a message box to user: current date and time, program name, number of transactions.

I understand a lot of logic just still struggling with putting it together. Please make as simple as possible and please leave good comments with each line of code to help me understand.
