Programming in the 1950s was very different from what we know today. The job we now know as that of a programmer was split between three roles. The programmer would write the algorithm meant to be implemented. Then, a specialized typist would type it into punch cards using a special machine. The programmer then had to manually verify that the punch cards were correct—although there were hundreds of them. Once happy that the punch cards were correct, the programmer would take them to the mainframe operator. Since the only computers in existence were huge and very expensive, the time spent on the computer had to be protected. The mainframe operator took care of the computer, ensuring that the most important tasks took precedence, and thus a new program could wait for days until it was run. Once run, the program would print a full stack trace...

Overview of this book
Functional programming enables you to divide your software into smaller, reusable components that are easy to write, debug, and maintain. Combined with the power of C++, you can develop scalable and functional applications for modern software requirements. This book will help you discover the functional features in C++ 17 and C++ 20 to build enterprise-level applications.
Starting with the fundamental building blocks of functional programming and how to use them in C++, you’ll explore functions, currying, and lambdas. As you advance, you’ll learn how to improve cohesion and delve into test-driven development, which will enable you in designing better software. In addition to this, the book covers architectural patterns such as event sourcing to help you get to grips with the importance of immutability for data storage. You’ll even understand how to “think in functions” and implement design patterns in a functional way.
By the end of this book, you’ll be able to write faster and cleaner production code in C++ with the help of functional programming.
