Say you have 10,000 lines of text, and you want to find the index of the line that contains the 302nd 'U'. You could do this with a while loop, but in the process you would find yourself setting up an index and dutifully incrementing it by 1 to keep track of the line you're currently looking at. A for loop is simpler here. |
