Answer / scarlet

the ability of general request to get different result is
polymorphism.the 3 types are function overloading,operator
overloading,virtual functions.application-allows object to
show different identities and results at run time.

Answer / khan

Poly mean many mphorm mean form, polymorphism mean use an entity in many forms. there are two types of polymorphism
1. Static Polymorphism
2. Dynamic Polymorphism

1. Static polymorphism is also called as Compile Time polymorphism. In Static polymorphism methods are overloaded with same name but having different signatures.So it is called as method overloading.

2.Dynamic polymorphism is also called as Run Time polymorphism. In this type of polymorphism methods have the same name, same signature but different in the implementation.
In Dynamic polymorphism methods are overridden so it also called as method overriding.

This program numbers the lines found in a text file. Write a program that reads text from a file and outputs each line preceded by a line number. Print the line number right-adjusted in a field of 3 spaces. Follow the line number with a colon, then one space, then the text of the line. You should get a character at a time and write code to ignore leading blanks on each line. You may assume that the lines are short enough to fit within a line on the screen. Otherwise, allow default printer or screen output behavior if the line is too long (i.e., wrap or truncate). A somewhat harder version determines the number of spaces needed in the field for the line numbers by counting lines before processing the lines of the file. This version of the program should insert a new line after the last complete word that will fit within a 72-character line.

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. Question Submitted By :: Sunil Kumar I also faced this Question!!

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
