Take each element and compare with other elements and swap the place for sorting/descending.

No, there is a much better way to do it. You don't need any swapping or sorting. Just make sure to choose the correct initial value before you get to the array.

Before you start searching, you need a value for max or whatever your largest result is to be. Choosing the wrong value for that will, of course, mean you fail to find the correct maximum. The same applies if you are looking for second largest.

let's try this approach...

How would you find the maximum? Once you know how to do that, there are several other approaches you can take, but we should start with baby steps.
