Why should this be the algorithmic level, and container.empty() not?

What about, when I put the empty call in a sub-function, e.g.


bool check_conditions()


    result = false;

    // ... do many checks

    return result && container.empty();



if (check_conditions())



Will the scope of automatic/local variables within function check_conditions() be extended until the end of push_back()?

No, that would be the algorithmic level where the compiler wouldn't
interfere at all.
