Function Overloading Vs Function Overriding

What is Function Overriding in C++?

Function overriding is a type of polymorphism in which we redefine the member function of a class which it inherited from its base class. The function signature remains same but the working of the function is altered to meet the needs of the derived class. So, when we call the function using its name for the parent object, the parent class function is executed. But when we call the function using the child object, the child class version will be executed....

Real-Life Example of Function Overriding

The best Real-life example of this concept is the Constitution of India. India took the political code, structure, procedures, powers, and duties of government institutions and set out fundamental rights, directive principles, and the duties of citizens of other countries and implemented them on its own; making it the biggest constitution in the world....

Types of Function Overriding in C++

Unlike other languages such as Java where function overriding is strictly done at compile time, C++ supports two types of function overriding:...

Compile Time Function Overriding

In compile time function overriding, the function call and the definition is binded at the compilation of the program. Due to this, it is also called early binding or static binding....

Runtime Function Overriding using Virtual Function

Unlike other languages like Java, the function overriding in C++ can be performed at both compile time and runtime. In all the above examples, the call to the overridden function is resolved during compile time. It is also called early binding where the function call is binded to its definition during compilation....

Function Overloading Vs Function Overriding

Function Overloading Function Overriding It falls under Compile-Time polymorphismIt can be both Compile Time or Runtime PolymorphismA function can be overloaded multiple times as it is resolved at Compile timeA function cannot be overridden multiple times as it is resolved at Run time Can be executed without inheritanceCannot be executed without inheritanceThey are in the same scopeThey are of different scopes....
