Console Application: Programming a Warehouse

Giovanbattista Barra

Hallo dear Team,

here I explain shortly how the programm should work:

I have to prpgramm a Warehouse with 75 boxes and I need to calculate the volume of them each time the user inserts info like height, width and length of each box.

Anyway I wrote in red what it doesnt work out

using System;

namespace Lagerverwaltung
{
class Program
{
private const byte kisteNrMin = 1;
private const byte kisteNrMax = 75;

struct Box
   {
       public int idBox;
   public int width;
   public int height;
   public int length;
   public int status;
   }

static int Volume(Box boxes)
{
int volValue;
volValue = boxes.length * boxes.width * boxes.height;
return volValue;
}

static void Eingeben(Box[] boxes)
{

for (int index = 0; index < 75; index++)
{

if (boxes[index].status == 0)
{
Console.Write("Insert the height {0} of the box: ", boxes[index].idBox);
boxes[index].height = Convert.ToInt32(Console.ReadLine());

Console.Write("Insert the width {0} of the box: ", boxes[index].idBox);
boxes[index].width = Convert.ToInt32(Console.ReadLine());

Console.Write("Insert the die length {0} of the box: ", boxes[index].idBox);
boxes[index].width = Convert.ToInt32(Console.ReadLine());

boxes[index].status = 1;

//here when I call the method volume doesnt work - i get 0 as result - why?

Console.WriteLine("The volume of the box is {0}", Volume(boxes[index]));

break;
}
else
{
Console.WriteLine("The box {0} is reserved.", boxes[index].idBox);
}
}
}

static void Delete(Box[] boxes)
{
Console.WriteLine("Which Box would u like to cancel? Please insert a number from 1 - 75.");
int number = Convert.ToInt32(Console.ReadLine()) - 1;

if (number <= 75 && number >= 0)
{
Console.WriteLine("The box was cancelled.");
}
//dont delete the same box you cancelled before

//that's why, make a difference (for example: you delete box number 5, thats's why the programm must calculate 74-1 and so on - here I try but it doesnt work)

else if (number == boxes[number].idBox)
{
Console.WriteLine("The box was already cancelled before");
}
}

static void Main(string[] args)
{
int insert = 0;
Box[] storeroom = new Box[75];

for (int index = 0; index < 75; index++)
{
storeroom[index].idBox = index + 1;

}
while (insert != 3)
{
Console.WriteLine("\nPlease chhose a programm:\n");
Console.WriteLine("[1] Insert Box");
Console.WriteLine("[2] Cancel Box");
Console.WriteLine("[3] End Program\n");

insert = Convert.ToInt32(Console.ReadLine());

switch (insert)
{
case 1:
Eingeben(storeroom);
break;
case 2:
Delete(storeroom);
break;
case 3:
break;
}
}
}
}
}

I hope you can really help me and thank u in advance.

Best regards

Giovanni

Accepted answer
The first error (volume == 0) occurs because you set the width twice, instead of the length.
Guest User7y ago
Shouldn't you be using the status property of a box to determine it's cancelled state?

I think your Delete should have something like this:

static void Delete(Box[] boxes)
{
Console.WriteLine("Which Box would u like to cancel? Please insert a number from 1 - 75.");
int number = Convert.ToInt32(Console.ReadLine()) - 1;
if (number <= 75 && number >= 0)
{
if (boxes[number].status == 0)
{
Console.WriteLine("The box was already cancelled before");
}
else
{
boxes[number].status = 0;
Console.WriteLine("The box was cancelled.");
}
}
}

and what about the second comments? Please see the code below:

//dont delete the same box you cancelled before
//that's why, make a difference (for example: you delete box number 5, thats's why the programm must calculate 74-1 and so on - here I try but it doesnt work)
----------------------------------------------------------------------------------------------------------
OR another possibility I tried but it doesnt work

if (number <= 75 && number >= 0)
{
Console.WriteLine("Box was cancelled.")
}
//dont delete the same box you cancelled before
else (kisteNrMax - boxes[number].idBox)
{
Console.WriteLine("the box was already cancelled!");
}

I want to try to cancel the box (in the else condition) that it was inserted before:
that means:
74 - 2 = 73 Boxes will still remain and not 72
because is the identification number of that box

and If i insert the number 2 once again: the system muss give out the message:
"the box was already cancelled!"

if i want to cancel further boxes for example numer 8
then the system must count 74 - 1

shall I need another for loop that decrement the deleted box?
