Man...for First year engg in Mumbai university..stick to the textboks..dont go online...
coz we guys r learning really basic stuff..even some wrong stuff..stuff dat has not been in use nowadays
Neways..get E.Balaguruswamy and study copy constructors
I dont have my copy lying around..but from what i remember..

It can be used to create a an object that is a copy of an already defined object..i.e. with class variabled given values.

Ok..found it..u sure are lucky..it was near my PC..page 139,balaguruswamy:
a copy constructor is use to declare and initialize an object from anoder object
i. Integer i2(i1);
this would define object i2 and initailize its values to dat of i1 variables
u cud also use integer i2=i1

this statements wont work if u havent defined a copy constructor.

i assume u know a constructor integer i3(10,50) wud initialize i3 variables to 10,50..in d copy constructor case..it wud give dem values of the object in the bracket...got it??
BTW..how does this come under open source??
