Lec 3 What is Object Oriented Programming OOP POP vs OOP C Tutorials for Beginners In the series of learning object oriented programming in C in the previous video we have installed our vs code an id visual studio code the compiler the compiler and the compiler We have also checked by running a simple program just to print hello world on the screen and yeah it was working so our laptop is all set now we can write down our programs Program is divided into parts that are known as procedure or function so program is divided Each function is having its own local data ld means local data and gde means global data Data movement is more so data is less secure in this case this function can update this data so data would be less secure Object oriented programming is not well suited for one thing in which we need more security Large and complex scalable applications the applications which require actively updated and maintenance this approach is not suitable for those things because there are interdependency among these functions many functions are there calling each and every function something like this processor oriented programming is not suitable for the complex and large scale applications because the main reason what is the data security so that s why we move to object oriented programming The main part of this video is just to get you familiar with object oriented program and how it is different from pop so how data security comes here The four pillars of object oriented programming that is abstraction encapsulation inheritance polymorphism and the main concept is classes and objects Without classes or objects we can not write down a program so those things also we ll discuss later right so i ll see the next lecture till then bye take care
