Overview of this book

C++ is a general-purpose programming language which has evolved over the years and is used to develop software for many different sectors. This book will be your companion as it takes you through implementing classic data structures and algorithms to help you get up and running as a confident C++ programmer. We begin with an introduction to C++ data structures and algorithms while also covering essential language constructs. Next, we will see how to store data using linked lists, arrays, stacks, and queues. Then, we will learn how to implement different sorting algorithms, such as quick sort and heap sort. Along with these, we will dive into searching algorithms such as linear search, binary search and more. Our next mission will be to attain high performance by implementing algorithms to string datatypes and implementing hash structures in algorithm design. We'll also analyze Brute Force algorithms, Greedy algorithms, and more. By the end of the book, you'll know how to build components that are easy to understand, debug, and use in different applications.

Quick sort


Quick sort is almost the same as the other sorting algorithms we have discussed so far as it divides the input array into two sublists, which are the left sublist and the right sublist. In quick sort, the process of dividing the array into two sublists is called partitioning. The partition process will pick an item to become a pivot and it will then use the pivot to divide the input into two sublists. If we are going to sort an array in ascending order, all items that are lower than the pivot will be moved to the left sublist, and the rest will be in the right sublist. After running the partition process, we will ensure that the pivot is in the correct position in the array. Although we can choose the item that will be the pivot, we will always choose the first item of the array as the pivot in this discussion.

Suppose we have an array {25, 21, 12, 40, 37, 43, 14, 28}. We are going to sort the array by using the quick sort algorithm. Please see the following diagram:

First, we choose...
