Is overloading compile time or run time?
Short answer. Compile time.
What gives run time polymorphism?
Virtual functions.
Two kinds
| Point | Compile | Run |
|---|---|---|
| Binding | early | late |
| Uses | overloading | virtual |
| Speed | faster | flexible |
Remember
| Overloading: compile time |
| virtual: run time |
Who picks the function, the compiler or the running program? Compile time binds early. Run time binds late. Compile time uses overloading. Run time uses virtual functions. Overloading is compile time. Virtual is run time.
