Peter Gottschling - Discovering Modern C++: An Intensive Course for Scientists, Engineers, and Programmers

EPUB is an open, industry-standard format for e-books. However, support for EPUB and its many features varies across reading devices and applications. Use your device or app settings to customize the presentation to your liking. Settings that you can customize often include font, font size, single or double column, landscape or portrait mode, and figures that you can click or tap to enlarge. For additional information about the settings and features on your reading device or app, visit the device manufacturers Web site.

Many titles include programming code or configuration examples. To optimize the presentation of these elements, view the e-book in single-column, landscape mode and adjust the font size to the smallest setting. In addition to presenting code and configurations in the reflowable text format, we have included images of the code that mimic the presentation found in the print book; therefore, where the reflowable format may compromise the presentation of the code listing, you will see a Click here to view code image link.

To my parents, Helga and Hans-Werner

The world is built on C++ (and its C subset).

Herb Sutter

The infrastructures of Google, Amazon, and Facebook are built to a large extent in C++. In addition, a considerable fraction of the underlying technology is implemented in C++. In telecommunications, almost all landline and cellular phone connections are driven by C++ software. Most importantly, all the major transmission nodes in Germany are handled with C++, which means that peace in the authors family unconditionally relies on C++ software.

Even software written in other programming languages depends on C++ since the most popular compilers are realized in C++: Visual Studio, clang , and newer parts of Gnu and the Intel compiler. This is even more true for software running on Windows which is also implemented in C++ (as well as the Office package). The language is omnipresent; even your cell phone and your car certainly contain components driven by C++. Its inventor, Bjarne Stroustrup, set up a web page with applications where most examples here come from.

In science and engineering, many high-quality software packages are implemented in C++. The strength of the language is manifested in particular when projects exceed a certain size and data structures are rather complex. No wonder that manyif not mostsimulation software programs in science and engineering are realized today in C++: the leaders Abaqus, deal.II, FEniCS, OpenFOAM, to name only a few; likewise the leading CAD software CATIA. Even embedded systems are increasingly realized in C++ thanks to more powerful processors and improved compilers (in which not all modern language features and libraries can always be used). Finally, we do not know how many projects would be realized in C++ instead of C if they had been started later. For instance, the authors good friend Matt Knepley, who is coauthor of the very successful scientific library PETSc, admitted that he would program the library today in C++ if rewriting was affordable.
