C++ Runtime

Understanding the runtime is crucial for writing performant software, debugging complex memory issues, and grasping how C++ differs from languages like C or Rust.

Unlike C, which has a very small runtime footprint, the C++ runtime is significantly larger because it handles complex features automatically. It includes: Understanding the runtime is crucial for writing performant

The global operator new and operator delete are part of the C++ runtime. They are typically thin wrappers over malloc / free but can be replaced by the user.
