Hash map is a data structure that stores key-value pairs and allows for fast retrieval of values based on keys.

• Hash map provides constant time complexity O(1) for insertion, deletion, and retrieval operations.

• It is commonly used to implement associative arrays, database indexing, and caching mechanisms.

• Example: Storing student grades with student IDs as keys and grades as values.

A union is a data structure that allows storing different data types in the same memory location, while a structure is a data structure that allows storing different data types in separate memory locations.

• A union uses the same memory location for all its members, so only one member can be active at a time.

• A structure allocates separate memory locations for each member, allowing multiple members to be active simultaneously.

• Unions are useful when memory needs to be shared betw...read more
