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

NAME

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.
