C++ for Financial Mathematics

Introduction

The book «C++ for Financial Mathematics» (author: John Armstrong, 2017, 388 pages) is a unique textbook that seamlessly combines learning the C++ programming language with its application in financial mathematics. Unlike many publications that either focus exclusively on financial theory or provide a superficial overview of code, this book offers a deep dive into the practical aspects of developing financial models in C++. It is intended for students, graduate students, and professionals who want to master modern quantitative analysis methods using one of the most performant programming languages.

What this book is about

The book is structured as a sequential guide from the basics of C++ to complex financial mathematics algorithms. The author starts with basic language concepts (data types, functions, classes, templates), but does so in the context of financial tasks. For example, learning about classes is immediately illustrated by creating classes to represent financial instruments. Next, key topics are covered:

• Numerical methods — solving equations, interpolation, numerical integration, Monte Carlo method.
• Option pricing models — binomial model, Black-Scholes model, finite difference methods.
• Memory management and performance — working with pointers, smart pointers, code optimization for financial calculations.
• Libraries and tools — using the C++ standard library, Boost, Eigen for linear algebra.
• Testing and debugging — writing unit tests, code profiling.

Who this book is for

The book will be useful for:

• Students of finance, mathematics, and IT majors who want to learn how to apply C++ in real-world financial tasks.
• Beginning developers in quantitative finance (quant developers) who already know the basics of C++ and want to deepen their knowledge in financial modeling.
• Professionals (traders, analysts) who want to automate calculations and create their own tools.

What the reader will learn

After studying the book, the reader will be able to:

• Write efficient and safe C++ code for financial applications.
• Implement numerical methods (Monte Carlo, finite differences) for pricing options and other derivatives.
• Work with matrices and vectors using the Eigen library.
• Understand and use object-oriented programming to create flexible financial models.
• Optimize code performance for working with large volumes of data.
• Test and debug financial algorithms.

Strengths of the book

One of the main advantages is its practical focus. Each chapter contains code examples that can be immediately run and modified. The author pays attention not only to the "what" but also the "why" — explaining why a particular approach is more effective in a financial context. The book is written in accessible language, without excessive mathematical abstraction, while maintaining rigor. The good structure is also worth noting: from simple to complex, with repetition of key concepts. I especially want to highlight the chapters on testing and profiling — this is rarely found in books on C++ for finance, but is critically important for industrial development.

Who it is recommended for

I recommend this book to anyone who wants to systematically study C++ in the context of financial mathematics. It will be useful both for beginners in C++ (provided they have basic programming knowledge) and for experienced developers who want to expand their knowledge in the financial field. The book is especially valuable for those preparing for work in investment banks, hedge funds
