What is the difference between overloaded functions and overridden functions?
-
Overloading is a dynamic or run-time binding and Overriding is static or compile-time binding
-
Redefining a function in a friend class is called function overriding while Redefining a function in a derived class is called a overloaded fucntion.

Redefining a function in a friend class is called function overloading while Redefining a function in a derived class is called as overridden fucnion.
Overloading occurs at compile-time when functions with the same name have different parameters. Overriding happens at runtime when a derived class provides a new implementation for a base class virtual function.
Function overloading is resolved at compile time: the compiler picks the matching function based on the number/types of arguments in the call, purely from static (compile-time) information — this is static/early binding. Function overriding, by contrast, is resolved at run time via virtual dispatch: the actual method invoked depends on the runtime type of the object (through a base class pointer/reference), which is dynamic/late binding. This is a foundational OOP distinction in C++/Java. The other options either invert this relationship or confuse overloading/overriding with friend-class vs derived-class redefinition, which is not how these terms are actually defined.
