binary search c++

Sure! Here is a response:

1. Set the lower bound (start) and upper bound (end) of the search range.
2. Calculate the middle index of the search range.
3. Check if the middle element is the target. If yes, return the index.
4. If the middle element is greater than the target, update the upper bound to be the middle index - 1.
5. If the middle element is less than the target, update the lower bound to be the middle index + 1.
6. Repeat steps 2-5 until the target is found or the search range is empty. If the target is not found, return -1.
