   This program totally sucks.

   It won’t even compile in Linux. clrscr needs conio.h

   Its also brute force search.
   You can find better algos in places like this for example http://wwwhomes.uni-bielefeld.de/achim/prime_sieve.html

   /*Thats the correct one*/

   #include
   main()
   {
   int m,n,i,j,,c;

   printf(“enter the number\n”);
   scanf(“%d %d”,&m,&n);
   c=0;
   for(i=m;i<=n;i++)
   {
   for(j=2;j<i;j++)
   {

   if(i==2)
   printf("%d",i);

   if(i%j==0)
   c++;

   }
   if(c==0)
   printf("%d",i);
   c=0;
   }

   }

   Public Class Form1

   Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
   Dim N, i As Integer
   N = Val(TextBox1.Text)
   For i = 2 To N – 1
   If N Mod i = 0 Then
   MsgBox(“the number is not a prime number”)
   TextBox1.Text = “”
   TextBox1.Focus()
   Exit Sub
   End If
   Next i
   MsgBox(“the number is prime number”)
   TextBox1.Text = “”
   TextBox1.Focus()
   End Sub
