returning a stack

Is it possible to return a stack to main? If so what is the proper way?
I have a simple function add that adds numbers to a stack, then I have a

Code:

---

return mystack;

---

and in main I have:

Code:

---

stack <double> x;
x = add();
cout << "stack has: " << x << endl;

---

but this is not working

What does "not working" mean? Compile errors? Runtime errors?

What is the definition of "add"?

compile errors,
I am getting an error

19 D:\Documents and Settings\Suchy\Desktop\stack_practice.cpp no match for 'operator=' in 'x = add()'

at the line:
x = add();

its just:

Quote:

---

double add ()

and I believe that is the problem since the function is declared as an double, but how can I declare it as a stack of double?

if add returns a single double you cant assign it to a stack. have the add function return a stack<double>

if you want it to return a stack of doubles, then tell it so! :) double is a datatype, just like 'stack<double>'.

yeah I want to return the whole stack of doubles

i know. what i was trying to say is that you just have to change the return type. 'double' is a datatype.. 'stack<double>' is another datatype.

Code:

---

stack<myDataType> myFunc()
{
  // ...
}

hope it helps!
