A tricky(maybe simple) question
Okay this might have a simple answer but its not clicking..
How to use the same member function say xyz() to perform 2 different tasks?
NO..not talking about Function Overloading. The same function is to have codes for both the operations.
An array is a data member of the class. xyz() should be able to accept the elements of the array when its called and then display it too..
Perhaps you want to make it a function template?

I dont want to use the function for different data types.. instead want to use it for different operations..
in case it can be done using function templates then plz tell..
I am not sure what you mean, but I can tell you that a well written function typically does one thing and does it well.

yeah..its just a question my prof asked..
said what concept of c++ can be used if we want to do so..
Use a parameter to select the operation, perhaps?
You might want to elaborate on this:

No ..parameter is an obvious way or an if statement in the function..but thats not to be used..
i'll give a sort of snippet..
class abc
{
int a[10];
public:
xyz()
{
...
... //accepting code
...
... //displaying code
}
};
nevermind..the question might be wrong [:P]
Well... the "accepting code" and "displaying code" part does not make sense. Accept what? Display the array, yes, but what else?
Or... is this question really about inheritance, polymorphism and virtual function overriding?

accepting code is to accept the elemets of array..
for(i=0;i<MAX;i++)
cin>>a[i];
display is similarly display..
its not a proper code to be written ..just a conceptual question. and figuring out what concept can be used is the problem..so dunno..
let it be..
Ah, as in reading into the elements of the array.
That's good, but I do not see where the "2 different tasks" comes in. Unless you are saying that the two tasks are precisely the reading from standard input and writing to standard output, in which case the answer is trivial: to use the function, just create an object of the class and call it.
