Find, for a vector (as I showed above) returns an iterator. I did similarly to you: I located the index of the value that mached the value returned by the Find iterator. String::find returns a position, which is what you were looking for, but sometimes one has to make do or locate some appropriate new thangy.

Note:
This loop may not stop where you want it to, nums[i] does not necessarily have a zero terminator at the end. It alos may have zero values in the middle. Stick with using the size() function to determine how many items there are.

If a and b are random access iterators, b-a is related to the number of elements between them. Not all containers support random access iterators, but some (eg std::vector) do. A pointer to elements in a contiguous array is a particular type of random access iterator......
