Lawn gui part C the hardest part

Question

To the Lawn application you created in Exercise 7a, add a
prompt that asks the user whether the customer wants to
pay (1) once, (2) twice, or (3) 20 times per season. If the
user enters 1 for once, the fee for the season is simply the
seasonal total. If the customer requests two payments,
each payment is half the seasonal fee plus a $5 service
charge. If the user requests 20 separate payments, add a
$3 service charge per week. Display the number of payments
the customer must make, each payment amount,
and the total for the season. Save the fi le as Lawn2.cs.

So I am thinking how to do it, do I have to do 3 more " if "statements that include the number that user type?
or I can just include || and the number in the current "if" statements, but it seems like its not going to work

To avoid disruption to your existing code I'd leave it unaltered but then add something like this ('top of head' so watch out for bugs): double totalFee = Math.Max(Math.Max(totalArea1 totalArea2) totalArea3); double userInputFrequency = Convert.ToDouble(textBox3); double instalment = 0; if (userInputFrequency == 1) { outPutLabel.Text +=  payable in one instalment of {0:C} a total payment of {1:C} totalFee totalFee); } else if (userInputFrequency == 2) { instalment = totalFee/2 + 5; outPutLabel.Text +=  payable in two instalments of {0:C} inclusive of a $5 service charge a total payment of {1:C} instalment instalment * 2); } else { instalment = totalFee/20 + 3; outPutLabel.Text +=  payable in twenty instalments of {0:C} inclusive of a $3 service charge a total payment of {1:C} instalment instalment * 20); }

It's not a bad effort Renu but there are a number of issues which I've attempted to correct below: static void Main(string[] args) { double length; double width; string input1; string input2; const int MIN = 400; const int MAX = 600; Console.Write(Enter the length of the lawn : ); input1 = Console.ReadLine(); Console.Write(Enter the width of the lawn : ); input2 = Console.ReadLine(); length = Convert.ToDouble(input1); width = Convert.ToDouble(input2); double area = length * width; double mowingFee1; double mowingFee2; if (area { mowingFee1 = 25; } else if (area >= MIN && area { mowingFee1 = 35; } else if (area >= MAX) { mowingFee1 = 50; } else { Console.WriteLine(Invalid input); return; } mowingFee2 = mowingFee1 * 20; Console.WriteLine(Weekly Mowing Fee is : {0} mowingFee1); Console.WriteLine(Mowing Fee For 20 weeks is : {0} mowingFee2); int input; string userInput; Console.WriteLine(Enter from these options whether you want to pay (1) once (2) twice or (3) 20 times per season.); userInput = Console.ReadLine(); input = Convert.ToInt32(userInput); double Payment1; if (input == 1) { Console.WriteLine(You have selected (1) i.e the fee for the season is simply the seasonal total : {0} mowingFee2); } else if (input == 2) { Payment1 = (mowingFee2 / 2) + 5; Console.WriteLine(You have selected (2) you are supposed to pay this much twice : {0} Payment1); } else if (input == 3) { Payment1 = (mowingFee2 / 20) + 3; Console.WriteLine(You have selected (3) you are supposed to pay this much 20 times : {0} Payment1); } else { Console.WriteLine(Invalid Input); } }

Hi Guys  I am new to This website  My name is Renu  and i am Learning c#:). I saw You guys writing this program for GUI  but i was writing the same program for console- Based application ..HERE is my code .. Please correct me if i am wrong somewhere  thanks :) static void Main(string[] args) { double length; double width; string input1; string input2; const int MIN = 400; const int MAX = 600; Console.Write(Ente the length of the lawn :); input1 = Console.ReadLine(); Console.WriteLine(Enter the width of the lawn ); input2 = Console.ReadLine(); length = Convert.ToDouble(input1); width = Convert.ToDouble(input2); double area = length * width; double mowingFee1; double mowingFee2; if (area { mowingFee1 = area * 25; mowingFee2 = (area / 25) * 20; Console.WriteLine(Weekly Mowing Fee is : {0} mowingFee1); Console.WriteLine(Mowing Fee For 20 weeks is :{0} mowingFee2); } else if (area >= MIN && area { mowingFee1 = area * 35; mowingFee2 =( area /35) * 20; Console.WriteLine(Weekly Mowing Fee is : {0} mowingFee1); Console.WriteLine(Mowing Fee For 20 weeks is :{0} mowingFee2); } else if (area >= MAX) { mowingFee1 = area /50; mowingFee2 = (area / 50) * 20; Console.WriteLine(Weekly Mowing Fee is : {0} mowingFee1); Console.WriteLine(Mowing Fee For 20 weeks is :{0} mowingFee2); } else { Console.WriteLine(Invalid input); } int input; string userInput; Console.WriteLine(Enter from these options whether you want to pay (1) once (2) twice or (3) 20 times per season.); userInput = Console.ReadLine(); input = Convert.ToInt32(userInput); double Payment1; double Payment2; if (input == 1) { mowingFee2 = (area / 50) * 20; Console.WriteLine(You have selected (1) i.e the fee for the season is simply the seasonal total :{0} mowingFee2); } if (input == 2) { Payment1 = (((area / 50) * 20) / 2)+5; Console.WriteLine(You have select (2) i.e Your payment is :{0} Payment1); } if (input == 3) { Payment1 = (((area / 50) * 20) / 20) + 3; Console.WriteLine(Your have select (3) you are suppose to pay this much 20 times :{0} Payment1); } else { Console.WriteLine(Invalid Input); } } } }

Wow really interesting that your great grandmother was a maid in the Buckingham Palace  so what kind of job you do Sam if u dont me asking you

Sam Hobbs · Answer

Yes I am in California but in southern California. The Silicon Valley is in northern California. I do not remember ever being in the Silicon Valley. Of course its official name is something else. I have a cousin in that area but I have never visited him there. I worked in San Francisco for about nine months many years ago and lived between San Francisco and the Silicaon Valley. Southern California does have many jobs too. There is the Los Angeles area which is quite large and there is Orange County which is smaller but there are many technical companies there too. There are many companies in San Diego too. For entry-level jobs my guess is that there is more opportunity in southern California but it is worth looking in northern California too. My father's mother was born in England; supposedly her mother was a maid in Buckingham Palace at the time. That is about the closest that my association with Vulpes comes. Otherwise our aquaintance is entirely limited to what you see here in C# Corner.

omg thats it? sometimes it sucks to be a foreigner... That's the biggest program I wrote so far! Well you and Sam helped me but still!

Vulpes · Answer

We're all friends on here :) If you initialize the three local variables: totalArea1 totalArea2 and totalArea3 to zero when you declare them then that should get rid of the error.

Prime b · Answer

So you two friends or something? Btw I did what u told me and that's what I get. I get an error in the double totalFee = Math.Max(Math.Max(totalArea1 totalArea2) totalArea3);  error Use of unassigned local variable I tried to move it around  and still gives me an error double userInPutLength userInPutWidth totalArea totalArea1 totalArea2 totalArea3; const double weekPay = 20; double instalment = 0; userInPutLength = Convert.ToDouble(textBox1.Text); userInPutWidth = Convert.ToDouble(textBox2.Text); double totalFee = Math.Max(Math.Max(totalArea1 totalArea2) totalArea3); totalArea = userInPutLength * userInPutWidth; double userInPutFrequency = Convert.ToDouble(textBox3); if (userInPutFrequency == 1) { outPutLabel.Text += String.Format(payable in one instalment of {0:C}. a total payment of {1:C} totalFee totalFee); } else if (userInPutFrequency == 2) { instalment = totalFee/2+5; outPutLabel.Text +=String.Format(payable it two instalments of {0:C} inclusive of a $5 service charge a total payment of {1:C}instalmentinstalment*2); } else { instalment = totalFee/20+3; outPutLabel.Text += String.Format( payable in twenty instalments of {0:C} inclusive of a $3 service charge a total payment of {1:C} instalment instalment * 20); } if (totalArea { totalArea1 = weekPay * 25; outPutLabel.Text = String.Format(For {0} square feet you have to pay {1:C} totalArea totalArea1); } if (totalArea >= 400 && totalArea { totalArea2 = weekPay * 35; outPutLabel.Text = String.Format(For {0} square feet you have to pay {1:C} totalArea totalArea2); } if (totalArea >= 600) { totalArea3 = weekPay * 50; outPutLabel.Text = String.Format(For {0} square feet you have to pay {1:C} totalArea totalArea3); }
