oops in c#

Why do we need OOPS? (Reusability with classes)

·         What is mean building

·         Problems with Procedural programming

o   Confusions -> We had all functions together - No Separation

o   Data is not protected

o   Increase in size because of physical include

o   Too many functions with different names doing same kind operations

o   Difficulties in reusing Existing Files
