std::erase,std::erase_if(std::vector) – std::erase,std::erase_if(std::vector)

Synopsis

Defined in header<vector>

    template <class T, class Alloc, class U>
    (1)(since C++ 20)

        void erase(std::vector<T, Alloc> &c, const U &value);

template <class T, class Alloc, class Pred>
(2)(since C++ 20)

    void erase_if(std::vector<T, Alloc> &c, Pred pred);
1) Erases all elements that compare equal to value from the container. Equivalent to c.erase(std::remove(c.begin(), c.end(), value), c.end());

2) Erases all elements that satisfy the predicate pred from the container. Equivalent to c.erase(std::remove_if(c.begin(), c.end(), pred), c.end());

Parameters

c – container from which to erase
value – value to be removed
        unary predicate which returns true if the element should be erased.
pred – The expression pred(v) must be convertible to bool for every argument v of type (possibly const) T, regardless of value_category, and must not modify v. Thus, a parameter type of T&is not allowed
        , nor is T unless for T a move is equivalent to a copy
        (since C++11).

Complexity

Linear.
