Implement Binary Search in C++
Problem Statement
Implement the binary search algorithm from scratch in C++ to locate a target value within a given sorted array. Your implementation must be iterative.
Requirements
- Language: C++
- Input: A sorted array of integers and a target integer value.
- Output: The index of the target value if found. If the target is not present in the array, the function should indicate this (e.g., by returning -1).
- Implementation: The solution must use an iterative approach (no recursion).
- Complexity Analysis: State the time and space complexity of your algorithm.
