Answer / poonam

Virtual function is a function that uses keyword "virtual"
with the datatype of the function. When the base class as
well as the derived class contains a function both having
the same name, just to resolve ambiguity and copy of the
same data again and again we use the keyword "virtual"
preeceeding it. It is used to achieve poymorphism.

Generally, in all C++ programs, texts are in white colour. Can we change the colour of the text(either input or output or both)? If so, help me out.
