Can someone answer my question?8

In a pass by reference function, if I keep calling it inside a while loop and want a value returned do I have to say return variable for everything I want returned ?

[LN3RX9L8]

and is it okay to have something like this where the only pass by reference value i want is the last one

int turn_plays(int array [], int boats, int &counts);

is this function prototype correct or can't be done in c++?

It works in Xcode but I am not sure if it is right

Thanks

I don't understand what you are trying to say here. Please give an example.

Works fine. References are not special.

Variable is a name for a memory location. When a function introduces a variable, it reserves memory. If it then passes a reference to another function, the called function will modify the memory location of the calling function.

If you call a function several times, in loop for example, each call in turn has the chance to do something.
