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.

Bubble sort


Bubble sort is a simple sorting algorithm, but it has a slow process time. It will divide an input list into two parts—a sublist of items already sorted on the right side and a sublist of items remaining to be sorted in the rest of the list. If we are going to sort a list of elements in ascending order, the algorithm will move the greatest value to the right position followed by the second greatest value and so on, similar to air bubbles when they rise to the top. Suppose we have an array of unsorted elements and are going to sort them using the bubble sort algorithm. The following are the steps required to perform the sorting process:

  1. Compare each pair of adjacent items, for instance array[0] with array[1], array[1] with array[2], and so on.
  2. Swap that pair if the items are not in the correct order. Since we are going to sort in ascending order, the correct order will be array[0] <= array[1], array[1] <= array[2], and so on.
  3. Repeat the first and second steps until the end...
