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.

Constructing a string from binary digits


A binary string is a string that represents a number in binary format and only contains 0 and 1. Supposing we have a number 3, the binary string will be 11, or the binary string of 9 is 1001.

Binary string is usually used to hold non-traditional data, such as pictures. Suppose we have the following black and white image:

If black is represented by 0 and white is represented by 1, we can create the following binary string to represent the preceding image:
