I want to print out the value in index [3], 27, but cannot make it work. Am I using the AND-operator wrongly or is it something else?

CODE
   int[] ints = new int[4];
            ints[0] = 24;
            ints[1] = 25;
            ints[2] = 26;
            ints[3] = 27;
          

            for (int i = 0;i < 4 && i > 2; i++)  
                Console.WriteLine(ints[i]);

Sorry, I was so caught up in the conditional part of the for statement that I forgot about the importance of setting i to a high enough value, or else the loop will end prematurely. sad.gif

addition: Plz excuse me for posting this in a rush, didn't take enough time to think for myself.

Sort of. Consider,
CODE

i=0
i<4 == true
i>2 == false
i<4 && i>2 == (true && false) == false


So, you're never really going to get off the ground here.

If you wish to start counting at three, try:
CODE

for (int i = 3;i < 4; i++)  


Although at that point you don't need a loop. You just need
CODE

Console.WriteLine(ints[3]);


Hope this helps.
