The information is present during compile-time. Function overloading occurs when we have many functions with similar names but different arguments. The arguments may differ in terms of number or type. We have three functions with the same name but different types of arguments.

We have achieved polymorphism. It also changes how the operator works. We know it as the addition operator for adding numerical values. After our definition, when placed between integers, it will add them.

When placed between strings, it will concatenate them. Runtime polymorphism is achieved through function overriding. Function overriding occurs when a function of the base class is given a new definition in a derived class. At that time, we can say the base function has been overridden.
