Why do we need OOPS? (Reusability with classes)
o What is mean building
o Problems with Procedural programming
§ Confusions -> We had all functions together - No Separation
§ Data is not protected
§ Increase in size because of physical include
§ Too many functions with different names doing same kind operations
§ Difficulties in reusing Existing Files
