A class only describes the data members and member functions that its objects will have, while an object is created from the class, occupies memory and holds actual values; one class may have any number of objects.

Overloading means defining several functions of the same name in the same class with different numbers or types of parameters, so the compiler decides which one to call; because the decision is taken before the program runs, it is called compile-time or static polymorphism.

James Gosling and his team at Sun Microsystems developed Java, which was first called Oak and was released under the name Java in 1995; its programs are compiled to bytecode and run on the Java Virtual Machine, which makes them platform independent.

Bjarne Stroustrup developed the language at Bell Laboratories, starting it as C with Classes and giving it the name C++ in 1983; it adds classes, inheritance and polymorphism to C while keeping C procedural power, which is why it is called a hybrid language.

Abstraction presents only what the user needs, such as the accelerator and brake of a car, and keeps the internal working out of sight; in C++ it is obtained through abstract classes with pure virtual functions and in Java through interfaces and abstract classes.

Encapsulation means binding the data members and the member functions that act on them inside one unit, the class, and keeping the data private so that it can be reached only through the methods provided; the standard illustration is a capsule holding the medicine inside it.

Recursion is a general programming technique in which a function calls itself, and it works equally well in procedural languages such as C, so it is not a feature of the object-oriented approach.

Simula 67, designed by Ole-Johan Dahl and Kristen Nygaard, introduced the ideas of class, object and inheritance and is therefore treated as the first object-oriented language, from which C++ and Java later borrowed.

It is a movable flap in the rear wing which a driver may open in marked zones of the circuit when close enough to the car in front; opening the flap cuts air resistance, raises the top speed and makes overtaking easier.

It is one of the best known one-day classics, famous for its cobbled roads and for the nickname the Hell of the North, but a single day race can never be a Grand Tour.

Points are awarded at the top of each categorised climb, and the rider leading that classification wears the white jersey with red dots, which is why the best climbers of a generation are remembered by this jersey.

The yellow jersey, called the maillot jaune in French, is worn by the rider with the lowest cumulative time over all the stages completed so far, and whoever wears it after the final stage in Paris wins the race.

The race was started by Henri Desgrange, the editor of the sports newspaper L Auto, which hoped to raise its circulation by organising a long bicycle race around France, and it has been run almost every July since then except during the two World Wars.

The driver from Coimbatore made his Formula One debut with the Jordan team in 2005 and so became the first Indian to compete in the championship, returning later with another team.

The FIA was founded in 1904 and is based in Paris, and besides running the Formula One World Championship and the World Rally Championship it also works on road safety and on the regulation of motoring clubs across the world.

The blue flag is shown to a slower driver, usually one who is about to be lapped, and ignoring it repeatedly brings a penalty, because the leaders must not be held up by backmarkers.

The circuit in Uttar Pradesh hosted the Indian Grand Prix three times, in 2011, 2012 and 2013, and Sebastian Vettel of Red Bull won on each occasion before the race was dropped from the calendar.

The first Formula One World Championship season opened with the British Grand Prix at Silverstone on 13 May 1950, and Giuseppe Farina of Italy, driving an Alfa Romeo, became the first world champion at the end of that season.

Services such as Google Docs and Microsoft 365 save a copy of a document each time it changes, show who edited what and allow a user to restore an older version, which is what makes group editing safe.

The cloud is reached over a network, so working permanently offline is the opposite of what the model offers; the dependence on connectivity is in fact listed among the limitations of cloud computing.
