  1. Object Oriented Programming

  2. Procedural Programming • Pros • Main control code block that calls functions • Custom functions written to solve each problem • Any data can be passed into any function • Fast • Low memory usage

  3. Procedural Programming • Cons • Function libraries can get very large • You cannot reuse functions for other problems without reworking them • Data can be changed inadvertently • The code is difficult to maintain • Changes to a function can introduce bugs in other sections of code

  4. Object Oriented Programming • Cons • More complicated design • Uses more memory • Code can be slower to run

  5. Terms to know • Object • A unit containing data and functions to operate on that data • Class • Defines what data and functions an object will have

  6. More Terms (the pros) • Abstraction • Hides the data inside the class, and provides controlled access through functions • Encapsulation • Having data and functions together in the same object • Inheritance • Reusability, lets you make small changes to classes easily • Polymorphism • Using the same function for different types of data (overloading)
