This command opens the file which is passed to it as an argument. We are quite used to the C++'s cin and cout functions contained in iostream library for reading and writing data, however, when working will real-life stuff, we find ourselves working with huge data saved as separate files and require our programs to read them, manipulate them and possibly write back to the files...

lora16 [44]

Answer:

1. Classes and objects

2. Inheritance

3. Polymorphism

4. Data hiding/ encapsulation

The inheritance is like the subclass of the object. Data hiding is a stage in oop where the codes or data are hidden from another users.

In the polymorphism stage, the object is given the ability to change to a sub-object, while in the interface stage a function or method signature is defined without implementing it.
