This book is intended to be an easy, concise, but rather complete, introduc- the ISO/ANSI C++ programming language with special empha- tion to sis on object-oriented numeric computation for students and professionals in science and engineering. The description of the language is platform- independent. Thus it applies to different operating systems such as UNIX, Linux, MacOS, Windows, and DOS, as long as a standard C++ compiler is equipped. The prerequisite of this book is elementary knowledge of cal- culus and linear algebra. However, this prerequisite is hardly necessary if this book is going to be used as a textbook for teaching C++ and all the sections on numeric methods are skipped. Programming experience in an- other language such as FORTRAN, C, Ada, Pascal, Maple, or Matlab will certainly help, but is not presumed. All C++ features are introduced in an easy way through concepts such as functions, complex numbers, vectors, matrices, and integrals, which are familiar to every student and professional in science and engineering. In the final chapter, advanced features that are not found in FORTRAN, C, Ada, or Matlab, are illustrated in the context of iterative algorithms for linear systems such as the preconditioned conjugate gradient (CG) method and generalized minimum residual (GMRES) method. Knowledge of CG, GMRES, and preconditioning techniques is not presumed and they are ex- plained in detail at the algorithmic level.

This book aims to provide a comprehensive analysis, with data simulations, of: 1) when investing in a Roth 401(k) or Roth IRA would be a better choice than investing in a traditional pretax 401(k) or IRA; 2) when a Roth conversion would be beneficial to an investor. A unique discovery from the analysis and formulas derived in the book is that Roth can still be a better option even if your future tax brackets are lower than your current tax brackets, depending on your investment time horizon. The hope is that an investor can utilize the formulas and data contained in this book when making strategic decisions on choosing between a Roth 401(k) and pretax 401(k) or between a Roth IRA and traditional IRA, or deciding whether to do a Roth conversion. Making a correct decision could potentially lead to tens or hundreds of thousands of more dollars in their retirement investment.

This book is an easy, concise but fairly complete introduction to ISO/ANSI C++ with special emphasis on object-oriented numeric computation. A user-defined numeric linear algebra library accompanies the book and can be downloaded from the web.
