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.

String in C++


String is a data type that stores a collection of characters. This collection can form a word or some information that can be understood by humans, it can also form a sentence from several words. In this section, we are going to discuss how to construct and use the string data type in C++.

Constructing a string using character array

In C++, a string can be composed by using an array of characters. When we compose a string using an array, we have to reserve a space to store a NULL character (\0) at the last array's element to indicate the end of the string. Suppose we want to create a string variable containing a name of a person called James; we need an array with at least six elements, since James is composed of five characters. Please take a look at the following diagram:

As we can see in the preceding diagram, we need an array with at least six elements to store a string containing five letters. There are several ways to create a string using character arrays. These are some...
