sorting in to Array values within range of two elements of 2nd Array

Hello,

I am trying to sort every element of Array1 in to different categories.

Array1 = 20,25,30,50,80,100

Array2 = 0,25,50,75,100

so every element of Array must be in rage of Array2.

the end result will be:

0 - 25 = 20

25 - 50 = 25,30

50 - 75 = 50

75 - 100 = 80,100

can any one help me with this.

thanks you.

Hi Kintesh did you try what Sam has suggested. Probably not the best solution but it works. Slightly modified my previous answer.

int[] arr1 = new int[] { 20, 25, 30, 70,80, 100 };
            int[] arr2 = new int[] { 0, 25, 50, 75, 100 };
            int a2c = arr2.Count();
            for (int i = 0; i <= arr1.Length-2; i++)
            {
                for (int j = 0; j <= arr2.Length - 2; j++)
                {

                    if (arr1[i] >= arr2[j] && arr1[i] <= arr2[j + 1])
                    {
                        MessageBox.Show("array" + arr1[i] + " is in" + arr2[j] + "," + arr2[j + 1]);

                    }
                }
            }

Hi

you can refer following code.It will help you to solve this issue of sorting in to Array values within range of two elements of 2nd Array.
```
  cat = 4; // user enters this number
    catnum = 100 / cat;
    for (int i=0; i <= cat; i++) {
        Array2.add(catnum * i);
    }
```

Okay, now I understand what you need; and if so then my suggestion does not help.

Try it out; study what it does. Don't expect someone to do all of it for you. I am not totally sure what you need but I hope that the code I showed will make it easy enough for you to do the rest.

but it doesn't do that i want. does it?

the end result will be:
0 - 25 = 20
25 - 50 = 25,30
50 - 75 = 50
75 - 100 = 80,100

The following code requires .Net version 4 so it won't work if your project is not set to use version 4. After this code executes, arr3 will have all contents from both arrays and arr3 will have the items sorted.
int[] arr1 = new int[] { 10, 30, 50, 70, 90 };
int[] arr2 = new int[] { 0, 25, 50, 75, 100 };
SortedSet arr3 = new SortedSet();
arr3.UnionWith((IEnumerable)arr1);
arr3.UnionWith((IEnumerable)arr2);

thank you Madhu K

but i get array out of range error when it gets to the last element i would be "100" but i+1 would be an error.

If I understand what you are asking, then you could copy both arrays into a third array and then sort that third array. Then all you need to do is to iterate (loop) through the third araray.

Here is a sample you can change it according to your requirement.
int[] arr1 = new int[] { 10, 30, 50, 70, 90 };
            int[] arr2 = new int[] { 0, 25, 50, 75, 100 };
            for (int i = 0; i <= arr2.Length; i++)
            {
                int s = arr1[i];
                if (s > arr2[i] && s < arr2[i+1])
                {
                    MessageBox.Show("array is in" + arr2[i] + "," + arr2[i + 1]);
                    break;
                }
            }
