What is the difference between Overloading and Overriding ?

We can achieve overloading within the same class as well as using parent-child relationship also.

If we create object for both class and calling same name function separately then what will be get output.

If we used overriding concept and after inherit then we will get drived classes 's output . So what is use of base class same name function. Why we use overriding

Happy Happy Sir
