C Program To Implement Dictionary Using Hashing Algorithms

Implementing a Dictionary in C Using Hashing Algorithms A dictionary is an abstract data type that stores data in key-value pairs. It allows for efficient data retrieval, insertion, and deletion based on unique keys. While high-level languages like Python and JavaScript provide built-in dictionary structures, implementing a dictionary in C requires building the underlying mechanics from scratch.
If a key maps to an occupied index, the program checks if the key matches an existing entry. If matched, it overwrites the value. If unique, it prepends a new Node to the head of that index's linked list. c program to implement dictionary using hashing algorithms
while (current != NULL && current->key != key) prev = current; current = current->next;
Note: This implementation utilizes because it handles table overflow gracefully and scales effectively. Architecture of a C-Based Dictionary If a key maps to an occupied index,
int main() Dictionary* dict = create_dict(TABLE_SIZE); put(dict, "apple", 10); put(dict, "banana", 20); put(dict, "grape", 30); put(dict, "apple", 99); // update

Hashing is a technique used to map a large input (such as a string or an integer) to a fixed-size output, known as a hash value or digest. This hash value is used to identify the location of the data in a data structure, making it possible to retrieve the data efficiently.
