why using list instead of list gives me an error?

Question

I tried to initialize a list of const string but I get an error. The simply code is the following

#include <string>
#include <list>

int main()
{
    std::list<const std::string> l;
    return 0;
}

When I compile I get the following error:

Can someone explain me why? Thanks

std::list must have a non-const and non-volatile value type by definition. You can initialize the list itself as const, so the content and length isn't changeable e.g.:

const std::list<std::string> l = {"a","b"};
