Array of Five Friuts class

Caleb Adeyemo

This is just a reminder that my question has not been answerd. I understand an answer was posted. But I believe there has not been any answer to the specific question. Please I want a complete help on this question so that next time, I will be able to write similar code in a perfect way.
Thanks.

Accepted answer
I know exactly what you're talking about as I wrote most of the code!

I thought at the time that it was a daft thing to do but, as I said in my previous post, those were the literal instructions - and the last time I gave someone a solution which departed from the literal instructions, the solution was marked as incorrect by their tutor.

If you don't want those lines to appear, then simply remove the following from the Main() method:

f.Search("pineapple");
f.Search("grape");

Just add a line in the 'while' statement:

while(true)
{
Console.Write("What fruit do you wish to search for ? ");
String name = Console.ReadLine();
if (name == "quit")
{
Console.WriteLine("\nEnd of the Fruit program");
return;
}
f.Search(name);
}

If you want the user to be able to end the program by typing either exit or quit, then change:

if (name == "quit")

to:

if (name == "exit" || name == "quit")

Yes, it's done!
Thanks.
*** Now, if I put exit or quit, how can I have an output---"End of the Fruit program" before press any key to continue or replacing press any key to continue?
Thanks again for your support.

Ok. I'll go and do that and get back with you.Thanks.

Thanks so much. For the sake of clarity, the output should look (exactly) like the following:

The Fruit class contains the following unsorted fruits.
grape
orange
apple
plum
pear

The Fruit class contains the following sorted fruits.
apple
grape
orange
pear
plum

What fruit do you wish to searc for? (Supposing I input pineapple), the output will be:
The fruit pineapple is not in the list.

What fruit do you wish to search for? (Here again if I input grape), the output should be:
The fruit grape is in the list.

What Fruit do yo wish to search for? ( Here I will input exit), then the output will be:
End of fruit program.

My point again is that going by the help I got in putting the code together, in the output there are these two lines-- (The fruit pineaaple is not in the list. The fruit grape is in the list). These two statements should not have come up until after I input the fruit to search for when prompted for this. But rather they came up even before asking for the fruit to search for, and it still prompted or asks for the fruit to search for after the two statements have already came up. However, the program still runs fine except for those two statements that supposed not to appear before it asks for the fruit to search for. Please run the code and see what I am talking about.
Thanks.

They're coming up first because you were told to search specifically for those two fruits - points 4 and 5 in the instructions on your other thread (http://www.c-sharpcorner.com/Forums/Thread/119263/a-C-Sharp-program-creating-a-fruit-class-that-will-store-five.aspx).

Thanks so much for your observation. Actually I just screwed up when I was making some changes! I forgot to change the {1} back to {0}. However, why are these two statements (" The fruit pineapple is not in the list " and "The fruit apple is in the list") coming up before it asks for the inputs to search whether or not in the list? Other than that, the program works fine.

only one problem in ur program that when we r giving fruit name which is not in list it is giving message that
The fruit grapeis not in the list instead of this it has to give message like when we r trying to search pineapple which is not in list so it has to give message The fruit pineapple not in the list .
try this it will work

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{

string[] names = {"grape", "orange", "apple", "plum", "pear"};
Fruit f = new Fruit(names);
Console.WriteLine("The Fruit class contains the following unsorted fruits.");
f.Print();
f.Sort();
Console.WriteLine("The Fruit class contains the following sorted fruits.");
f.Print();
f.Search("pineapple");
f.Search("grape");
Console.WriteLine("Type quit to end the program at any time\n");
while (true)
{

Console.Write("What fruit do you wish to search for ?");

String name = Console.ReadLine();

if (name == "quit")

return ;
f.Search(name);

}
}
}

public class Fruit
{
string[] names;
public Fruit(string[] names)
{
this.names = names;
}
public void Print()
{
foreach (string name in names) Console.WriteLine("{0}",name);
// Console.Write();
Console.WriteLine();
}
public void Sort()
{
Array.Sort(names);
}
public void Search(string name)
{
if (Array.IndexOf(names, name) == -1)
{
Console.Write("The fruit {0} is not in the list",name );

}
else
{
Console.WriteLine("The fruit{0} is in the list", name);
}
Console.WriteLine();
}

}
}

You did mistake in Console.Write("The fruit {1}is not in the list",names ); instead of writing names u should write name there.

I went back again to make some changes to the code and the output now is:
The Fruit class contains the following unsorted fruits.
grape
orange
apple
plum
pear
The Fruit class contains the following sorted fruits.
apple
grape
orange
pear
plum
The fruit grapeis not in the list
The fruitgrape is in the list
Type quit to end the program at any time
What fruit do you wish to search for ?

Almost done! Pls help me to check it agai.
Thanks.

Thanks so much. The output this time around looks somehow, and is posted here for your assesment please.
The Fruit class contains the following unsorted fruits:grapeorangeappleplumpear
The Fruit class contains the following sorted fruits:applegrapeorangepearplum
The fruitpinappleis not in the list
The fruitgrape is in the list
Type quit to end the program at any time
What fruit do you wish to search for ?

Please kindly help to see where the problem is.
Thanks.

For the output to be in precisely that form, the program will need to be written as follows:

using System;

public class Fruit
{
string[] names;

public Fruit(string[] names)
{
this.names = names;
}

public void Print()
{
foreach(string name in names) Console.Write("{0} ", name);
Console.WriteLine();
Console.WriteLine();
}

public void Sort()
{
Array.Sort(names);
}

public void Search(string name)
{
if (Array.IndexOf(names, name) == -1)
{
Console.WriteLine("The fruit {0} is not in the list", name);
}
else
{
Console.WriteLine("The fruit {0} is in the list", name);
}
Console.WriteLine();
}
}

class Program
{
static void Main()
{
string[] names = {"grape", "orange", "apple", "plum", "pear"};
Fruit f = new Fruit(names);
Console.Write("The Fruit class contains the following unsorted fruits : ");
f.Print();
f.Sort();
Console.Write("The Fruit class contains the following sorted fruits : ");
f.Print();
f.Search("pineapple");
f.Search("grape");
Console.WriteLine("Type quit to end the program at any time\n");
while(true)
{
Console.Write(" Type fruit to search for : ");
string name = Console.ReadLine();
if (name == "quit") return;
f.Search(name);
}
}
}

Hello. Thanks again for helping me. I believe I'm missing something here because the output was a little bit different from what I was expecting. When I entered the fruit to search for, there was no result as whether it was found or not. In other words, the output supposed to be this: The Fruit class contains the following unsorted fruits grape orange apple plum pear The Fruit class contains the following sorted fruits. apple grape orange pear plum When I entered fruit to search for especially "pineapple"; the output supposed to be "The fruit pineapple is not in the list." When I entered "grape" for the fruit to search for again, the output supposed to be,"The fruit grape is in the list". Please help. Thanks again.

Thanks so much for a job welldone! To say that I've gained a lot from your efforts in assisting/helping me is an understatement. Hope to see more of your beautiful works again.

I really wish that you would have tried to do the part I asked. I would have helped if you needed it but I wish you had the opportunity to do some learning. You aren't learning a thing by getting it all done for you.

Note that I am not doing this to make things easy for me. It is more work to teach someone than it is to do the work for them.

Caleb,

Read though these two links (ignore the technical stuff):

http://msdn.microsoft.com/en-us/library/6tf1f0bc.aspx

http://msdn.microsoft.com/en-us/library/7eddebat.aspx

and then have a go at completing the two remaining methods.

The Sort() method can be done in one line and the Search() method in four to six lines, depending on how you like to space stuff out on the console.

If you get stuck, we'll help you finish it but it's important to do some thinking yourself or you'll get no benefit from the exercise.

For some reasons I did not see this beautiful work you have done otherwise I would have instantly expressed my sincere appreciation! Good job! Thanks a lot.
Honestly speaking, I'm learning. I'll be appreciative of your efforts to complete the job for me. There's no need posting the mess I did!
Thanks.

OK, though it's quite a 'bare bones' assignment to start with, here's a skeleton program.

I've implemented one of the methods (Print) and it remains now for Caleb to implement the Sort and Search methods:

using System;

public class Fruit
{
   string[] names;

   public Fruit(string[] names)
   {
   this.names = names;
   }

   public void Print()
   {
   foreach(string name in names) Console.WriteLine(name);
   Console.WriteLine();
   }

   public void Sort()
   {
   // TO Do
   }

   public void Search(string name)
   {
   // TO DO
   // print out whether 'name' was found or not
   }
}

class Program
{
   static void Main()
   {
   string[] names = {"grape", "orange", "apple", "plum", "pear"};
   Fruit f = new Fruit(names);
   f.Print();
   f.Sort();
   f.Print();
   f.Search("pineapple");
   f.Search("grape");
   Console.WriteLine("Type quit to end the program at any time\n");
   while(true)
   {
   Console.Write(" Type fruit to search for : ");
   string name = Console.ReadLine();
   if (name == "quit") return;
   f.Search(name);
   }
   }
}

Good. Now we have all the history. I hope we can get some cooperation from Caleb. Perhaps someone should start with a skeleton or something. Caleb sure wants a nudge. I hope a nudge is all that Caleb needs to get started.

Frogleg, see A C# Program creating a Fruit Class that will store five fruits in an array, sort and search for a given fruit name. In that thread Caleb said "This is not a homework.". I think we have established that it is homework but we would have helped Caleb if Caleb had proceeded in that thread. I am not sure what Caleb is asking for but I think most of us want something more to start with. The important thing is for Caleb to learn and to the extent Caleb is trying to learn, I hope we are able to help Caleb.

Well upload your bad assignment and we will help you

Caleb Adeyemo15y ago
Well, I don't really have anything to hide here or trying to be economical with the truth! This was an assignment before but since I made a woeful grade on it, I considered it necessary to know how to do it in case of another time. I believe so much in this forum hence, I decided to join so that I can learn better.
Thanks so much for your concern.

Sam Hobbs15y ago
Please next time be honest and say that you have a class assignment.

Also note that we are very concerned about the next time. We want you to be able to do things like this yourself next time instead of depending on others to do it all for you. Please try to do it. Just try.
