map

A hashmap implementation in C11 with djb2 hash function

The hashmap algorithm consist of a bucket with a pair of key and values and a hash value that will to index the address of the correct bucket

Some implementations added a Linked List to solve the Hash Collision problem

How to build this project

Just type

mkdir build
cd build
cmake ..

How to see the result

./map 2> /dev/null

Dev information

The default hash algorithm

/* The best string hash function, created by Dan Bernstein */
unsigned long djb2_hash (unsigned char *str)
{
    unsigned long hash = 5381;
    int c;

    while ((c = *str++))
        /* HASH * 33 + C */
        hash = ((hash << 5) + hash) + c;

    return hash;
