Get and set

Question

How can I do something like this :
box.getContent().setColour("something");
Where box.getContent() returns an object that has method setColour(blabla)

Because when I do it the setter doesn't work. I have tried everything... Please help me.

Answer 1

The function setColor(...) must be return by reference on object,
i.e. :
Class & setcolor(...) { ... return *this; }

Answer 2

Make a class ball
Define method setcolour() in it .
Then make class box
And declare data member as object of class ball.
It will look like this....
Class ball
{
Private:
Char colour[8];
Public:
Setcolour( char[] colour_name)
{
Colour=colour_name;
}
}

Make class box...
Class box
{
Public:
Ball b;
Private:
Ball getContent()
{
Return a;
}
}

If you don't get it share me your code.. we will solve it..

Answer 3

Shubham, one thing, what type of Setcolour(...) ?

Answer 4

Yes I have classes. But it doesn't work. The idea is that I have boxes and balls. The balls can be inside the boxes. I want to change the colour of some balls in the box but it doesn't work the way I wrote it...

Answer 5

stamb why??

Answer 6

What why? Your program ok?

Answer 7

Void setcolour(char colour[])

This member function will return void type.
It will just change the colour property of ball object.
