This lesson is part of C · All levels

Summary

Data structure is the way data is stored and organized, whereas algorithms are the steps of processing it; both work together to make a program faster and more memory-efficient. The right choice of structures such as arrays, linked lists, stacks, queues, trees, or hash tables greatly affects the program's performance. This lesson opens up a series of data structures and algorithms (DSAs) in C, which are implemented directly with pointers, struct, and dynamic allocation.

Key points

Examples of data structures: array, linked list, stack, queue, tree, graph, and hash table.
Abstract data type (ADT) defines behavior such as stack operations, not how it is implemented.
Search and sequencing algorithms were the foundation before studying more complex data structures.
Each choice of structure influences the complexity of time and space, so it must be adapted to the needs.
In C, DSA is built from a combination of pointers, struct, and dynamic memory allocation functions.
