Before blogging about some of the uses of Std::find and std::find_ if, but not about the custom classes stored in vectors, how to use Std::find and std::find_if to find them. First define a class: Class Item { private: std::string m_itemid;

The Hash table stores the elements by mapping the key values to a location in the tables. The value of the given keyword, based on the mapping, computes the storage location of the element to access the element. in hashing, the conflict refers to
