What are some effective searching techniques in C++?

What are some effective searching techniques in C++?

In C++, common searching techniques include linear search, binary search, and using STL algorithms like std::find.

Can you explain how binary search works?

Binary search works by dividing a sorted array in half, repeatedly narrowing down the search range until the target is found.

What is the time complexity of binary search?

The time complexity of binary search is O(log n), making it much more efficient than linear search for large datasets.

Are there any built-in functions in C++ for searching?

Yes, C++ provides several built-in functions in the Standard Template Library (STL), such as std::find and std::binary_search.
