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

{{cpp/container/{{{1}}}/navbar}}

Defined in header [[cpp/header/{{{1}}}|<{{{1}}}>]]
template< ..., class U > void erase(std::{{{1}}}<...>& c, const U& value);	(1)	(since C++20)
template< ..., class Predicate > void erase_if(std::{{{1}}}<...>& c, Predicate pred);	(2)	(since C++20)

1) Erases all elements that compare equal to value from the container.

2) Erases all elements that satisfy the predicate pred from the container.

Parameters

c	-	container from which to erase
value	-	value to be removed
pred	-	unary predicate which returns ​true if the element should be erased. 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.
