How do I design a hash function in C++?

How do I design a hash function in C++?

To design a hash function in C++, you need to consider the data type you're hashing and the desired properties like speed and collision resistance.

What are some common techniques for creating hash functions?

Common techniques include using modular arithmetic, bit manipulation, and combining multiple hashing algorithms.

Can you give me an example of a simple hash function?

Sure! Here's a simple example: for a string input, you can sum the ASCII values of the characters and take the modulus with a prime number.

How do I handle collisions in my hash function?

You can handle collisions using techniques like chaining (linked lists) or open addressing (probing).
