C++

advanced

C, but with more ways to shoot yourself in the foot. And classes.

C++ is C with object-oriented programming, templates, and a standard library that actually does things. It's complex, but it's used for game engines, browsers, trading systems, and anything where performance is non-negotiable.

Setup

C++ uses the same compilers as C. GCC, Clang, and MSVC all support C++. Use the g++ or clang++ commands instead of gcc/cc.

Bash

# Same options as C — install GCC via MSYS2 or use Visual Studio
# With MSYS2:
pacman -S mingw-w64-ucrt-x86_64-gcc

# Use g++ to compile C++:
g++ hello.cpp -o hello -std=c++17

# Visual Studio (MSVC):
# cl /std:c++17 hello.cpp
