C++ Modern Features Bootcamp

This bootcamp aims to provide you with foundational knowledge of modern C++ programming. The C++ language is extremely rich and broad in its features — it cannot be fully covered in a single bootcamp, and frankly, this language is best learned through practice. The staff believes that the 15-445 course will make you a more confident C++ programmer! That said, we do cover some C++ concepts that are essential for completing the programming assignments. This tutorial does not cover basic C/C++ syntax; it focuses primarily on C++ programming features, especially concepts that do not exist in C.

This repository provides a structured, bilingual (English & Chinese) introduction to modern C++ — derived from CMU's 15-445/645 bootcamp and extended with detailed notes, translated code comments, and community contributions. It is designed for self-paced learning and as a reference for developers transitioning from C to modern C++.

Build

The bootcamp contains several C++ source files located under each chapter directory — it is recommended to study them in depth. Each source file compiles into an executable with the same name. Use CMake to build all executables:

$ mkdir build
$ cd build
$ cmake ..      # invoke CMake to locate CMakeLists.txt in the parent directory
$ make -j8      # invoke Make to compile; -j enables parallel builds (8 CPU cores max)

After running these commands, the generated executables will be in the build directory. For example, 1 - References and Move Semantics/references.cpp compiles to the references executable under ./build. The same applies to all other source files.

References

While this bootcamp strives to be as comprehensive as possible, it still only covers the fundamentals of using modern C++. As you apply C++ to build larger programs, you will need to consult many other available resources. Here are a few examples — they are all very comprehensive (far more so than this bootcamp), though they may be somewhat less approachable in terms of readability. That said, I believe it is still worth trying to read and understand these materials, especially when working on projects.

1. cppreference: an unofficial but fairly accurate summary of the C++ and C standards, with examples
2. cplusplus: includes both a C++ language tutorial and a C++ library reference
3. Modern C++ Tutorial: this GitHub repository contains useful information and practice exercises
