Sort numbers from lowest to highest in C#

[fenners87]

Hi

I need to write a programme that asks users to enter 10 numbers and once the numbers have been entered i then need to sort them from lowest to highest in C#

i.e 45, 3, 64, 6, 24, 75
3, 6, 24, 45, 64, 75


I am unsure on how to do it and what to use?
So far i have used strings to store the numbers entered,

if anyone could help ill be greatful!!

thanks

Hi,

Why are you using strings?


You could only use array of integers.

To sort them try using two for loops with different counters so that secound loop is alocated inside first.

After this you need to see wich element is smaller(if you want to sort from highest to lowest than test wich is larger)

Then you have two choices:

1. Use a temporary array wich wich will store smaller number,then assign to smaller number value of larger and to ex larger value of temp.aray;

2.Simple do it without temp array.

It should be like:

if(a[j]<a[i])
{
      a[i]=a[i]+a[j];
      a[j]=a[i]-a[j];
      a[i]=a[i]-a[j];
}
 
/*else do nothing.*/

Note: j is starting from j=i+1 in secound for loop.

1) why not store them as numbers, as then you will be able to make numeric comparisons (greater than, less than, etc...)? I would think all you need is a numeric array and a tmp var.
2) As this is C#, I am moving this to the .NET forum.

Assuming you are using C#.NET, then the Array class has a Sort method. So, if you are allowed, the sort is only one line:

int[] MyNumbers = new int[] {45,3,64,6,24,75,3,6,24,45};
Array.Sort(MyNumbers);

Note -- this only answers your sort question, you still have to get the numbers from the user and print out the sorted array.

You can try dynamic array ArrayList to Add item and Sort them, and you also don't have to worry about predefined length of array.

Hi, Savage could you please explain with words what this function does? Because it works correct for me, but i just can't figure out how it works... I have been staring at it now for more then 30 minutes.

I think that i get it now. Thanks!
