containers of arrays?

[Stephen J. Fromm]

I take it I cannot form a container of an array type? For example,
stack<string[3]> parentStack;

TIA,

You can have containers of arrays, but the declaration youv'e posted
above is faulty. Youv'e declared a stack where each element is 3
strings. This is fine in principle, but probaly what you should do is
declare a struct that defines the stack elements, then declare the
stack as a stack of those things, like this:

struct STRINGS
{
string m_Strings[3];
}; // STRINGS

int main()
{
std::stack<STRI NGS> stk;
return 0;
}

No, you can't.

No, it's not. Arrays are not assignable and as such, they cannot be used
as elements of standard containers. The above code should not be
accepted by your C++ compiler.

That would work.

Victor,

Yes, I can form, or yes, I cannot form?

Right, that's what I ended up doing.

What I'm curious about is whether I can *directly* define a stack<...>
of an array or not. My compiler decidedly didn't like it.

Cannot. Arrays do not satisfy the requirements for contained
items: CopyContstructi ble and Assignable.

Not.
