Question

In Lecture 3, the last example added converted a number to a string, then converted each element of the string to an integer and added them together. The digits 1952 added together = 17. What's unclear to me is how the code operates to go from one string element to the next. The code does not explicitly show this operation being performed. What am I missing? Here is the code: http://dpaste.com/550284/

Answer 1

I just read how for loops work and now understand what happens. A for loop will always walk through the sequence in the ordered list, which here is 1, 9, 5, and 2.

Answer 2

yep
