On the third module on how to code in c# we learned about what objects and classes are. I learned that objects are a concrete entity based on a class, while classes are what defines a data type for objects, . You can add different value to the classes and/or object. this will help the program detect what you’re trying to do. Objects have their own unique characteristics, and it doesn’t have to have something physical. I also learned that c# has stacks and heaps in its storage. That’s how the program stores things. A stack is all the references in the code, while a heap connects those references to the actual object.
