Could any one explan me what happens in this program. main(){ int i=10; i=(++i)/(i++); printf("i=%d",i); }

The answer is 2, because the statementi = (++i) / (i++)will be processed from left to righti = (++10) / (10++)which meansi = 11/10++Here still ++ operator is not executedi = 1++; // 1 because it is an integer operationi = 2;if you changei = (++i) / (++i) you will see 1

Abstraction: We don't have to bother about the data type of the object while accessing it.Encapsulation: We put all the correlated data and methods in a class.Faran Shabbir

Explain the Encapsulation principle
Encapsulation is a process of binding or wrapping the data and the codes that operates on the data into a single entity. This keeps the data safe from outside interface and misuse. One way to think about encapsulation is as a protective wrapper that prevents code and data from being arbitrarily accessed by other code defined outside the wrapper.

Every program deals with two elements:1) Data 2) Code [function]Combining these two elements into a single unit is known as Encapsulation (Binding).

The Class is a blueprint which holds the code, but the instance is the real object inside the memory so we can access its properties and methods in the Run-time.

In my last interview, the interviewer ask me a question which is similar this one. No, class is not an Object or Object is not a class, we just say that Class is a prototype to creates objects. First we need a prototype then we have object, wihtout prototype or class object cannot be exist.

While copying the objects if you say X a = b and asssume that '=' operator is overloaded then what it will call, a copy constructor or operator overloading function
adeelqamar8

Copy constructor would be called to perform the deep copy of object b into object a.

It is not operator overloading, it is just copy constructor which assign that the value of b is copied to a.
