C++ Stacks Understanding

[reef sail]

I don't understand what's the need of container parameter for Stacks, because even if I change it how would it affect the Stack ?
My guess on it is that the Stack stores the values it has in a Vector causing it to match the speed of a Vector, but that doesn't make sense in a lot of ways.

what argument are you talking about specifically?

[reef sail]

What do the containers of Stacks do ?

[viscid basalt]

I mean std::stack behaves like a stack? it's a LIFO data structure

[reef sail]

Yea I read that, but how does changing the container type affect the stack ?

[viscid basalt]

so yeah, thats a bit of a complex awnser, std::stack is essentially an interface for LIFO behavior but it can be implemented in any data structure as long as it provides a set of functions

what gives it more flexibility

[reef sail]

So all I need to know is affects the speed ?

Is that the surface level knowledge ?

[viscid basalt]

honestly most of the time you never touch that parameter

the std::decue<t> is plenty in most cases

[reef sail]

alright, but when can the need to change the parameter arise ?

or cases I might have to change the parameter ?

[viscid basalt]

honestly you would change the underlying type when you want different behaviral patterns from your types, meaby you have a custom allocator you can now provide your own type that uses your custom allocator but have a nice and simple std::stack interface

[reef sail]

alright

thx :D
