Sets c as the stream’s fill character. Behaves as if member fill were called with c as argument on the stream on which it is inserted as a manipulator (it can be inserted...
A destructor is another special kind of class member function that is executed when an object of that class is destroyed. They are the counterpart to constructors. When a variable goes out of scope,...
A copy constructor is a special constructor in the C++ programming language for creating a new object as a copy of an existing object. The first argument of such a constructor is a reference...
In object-oriented programming, a friend function that is a “friend” of a given class is allowed access to private and protected data in that class that it would not normally be able to access...
A friend class in C++, can access the private.protected and public members of the class in which it is declared as a friend. On declaration of friend class all member function of the friend...
Every class defines its own new scope and a unique type. The declarations of the class members within the class body introduce the member names into the scope of their class. Two different classes...
Whenever we create object of a class then default constructor will be called automatically. If we don’t define constructor in our class then there is hidden default constructor which is not seen, but we...
Static Variables Member variables of a class can be made static by using the static keyword. Static member variables only exist once in a program regardless of how many class objects are defined! One...
The size of empty class is 1 because The standard does not allow objects (and classes thereof) of size 0, since that would make it possible for two distinct objects to have the same...
Consider the following code in order to pass class objects as arguments to functions.
The const variable specifies whether a variable is modifiable or not. The constant value assigned will be used each time the variable is referenced. The value assigned cannot be modified during program execution. class...
i++ shows that the value of i is post incremented after operation, ++i shows that its pre incremented before operation. Example Output
1. Proper pointer initialization One common way is to assign the pointer an address to a previously defined variable. For example: Or, equivalently, Other common ways include assigning the pointer the address of memory...
Segmentation Fault, bus error or access violation is generally an attempt to access memory that the CPU cannot physically address. It occurs when the hardware notifies an operating system about a memory access violation....
Reverses the order of the elements in the range [first,last). Example Output
