questions about STL erase example

[Allerdyce.John]

I am reading a STL example:

bool badValue(int x); // return whether x is 'bad'.
vector<int> c;
c.erase( remove_if(c.begin(), c.end(), badValue), c.end());

My question is the above code, does it remove ONLY THE FIRST item where
badValue return false or
ALL ITEMs where badValue return false.

Thank you.

vector<int> c;
c.erase( remove_if(c.begin(), c.end(), badValue), c.end());

My question is the above code, does it remove ONLY THE FIRST item where
badValue return false or
ALL ITEMs where badValue return false.

It returns all items for which the predicate yields 'true'.

I believe it removes all "bad" items.
