Summary of How to Create A Hash Table Project in C++ , Part 1 , Setting Up the Hash Table Project

Main Speaker

• Paul

In this video, Paul introduces the process of creating a hash table project in C++ using NetBeans. He begins by setting up a new C++ application project named "hash table video" and outlines the initial steps for file creation, including a main.cpp, hash.cpp, and hash.h file.

Key Points Covered

• Project Setup
  • Creating a new C++ project in NetBeans.
  • Naming the project and ensuring the main file is set up correctly.
• File Creation
  • Adding additional source and header files (hash.cpp and hash.h).
  • Including necessary libraries such as iostream and string for input/output operations and string manipulation.
• Class Definition
  • Defining a hash class in hash.h with a public function prototype for a hash function that takes a string key and returns an integer index.
  • The hash function will convert the string key into an integer index representing the location in the hash table.
• Hash Function Logic
  • The video explains how the hash function will work conceptually, including an example where a key is hashed to an integer and then used to determine the index in the hash table by taking the remainder when divided by the table size.
• Next Steps
  • Paul indicates that the next video will involve defining the actual implementation of the hash function.
