How to get largest and second largest in an array of integer.

I just want to ask what should be the way to do it, not asking for code.
So currently, I declare 2 variables: largest and second largest.
I go thru the array of integer, and state:

if (array[i] > largest){
largest = *array[i];} else if (array[i] > second largest) { second largest = *array[i]}; 

Please correct me
