  • Step 2: Know that C++ has a Standard Library that provides many useful functions.
  • Step 3: Identify the specific function for binary search in the C++ Standard Library, which is std::binary_search.
  • Step 4: Learn how to use std::binary_search by including the necessary header file <algorithm> in your C++ program.
