and if we use '+' with two strings then operator '+' can
concate two string is known as operator overloading.
or
operator overloading means one operator can perform multiple
operation based on given arguments.

Answer / riya piyush jain
Operator overloading (less commonly known as operator ad-
hoc polymorphism) is a specific case of polymorphism in
which some or all of operators like +, =, or == have
different implementations depending on the types of their
arguments. Sometimes the overloadings are defined by the
language; sometimes the programmer can implement support
for new types.

it may be defined as an operator performing different
operations.for ex-arithmetic operators such
as(+,-,*,/,++,--) etc..

Answer / msn
Making an operator doing different operation other than
the normal one is termed as operator overloading..
Say for example Operator + is normally used to add numbers
but we can add another function concatenate two strings

Answer / karthika
usually operators dealing with basic data types,operator
overloading allows the users to give additional meaning to

Question In a class, there is a reference or pointer of an object of another class embedded, and the memory is either allocated or assigned to the new object created for this class. In the constructor, parameters are passed to initialize the data members and the embedded object reference to get inialized. What measures or design change should be advised for proper destruction and avioding memory leaks, getting pointers dangling for the embedded object memory allocation? Please suggest.

Answer # 1 use copy constructors 0 Shanthila There is something to be taken care in destructor, in copy constructor, suppose the memory is assigned to the embedded member object pointer with the parameter passed value, but if some other objects of different class also are pointing to this memory, then if some one deletes the object then this class member pointer object will become dangling, or if the object is not deleted properly then there will be memory leak. Please suggest the design change required to handle or avoid this situation
