Erase() function to remove a range of elements from a vectorWe can also remove a range of elements by passing first and last position in the erase function. Syntax: For removing a range of elements: vector_name.erase(iterator first, iterator last);Example: vector1={10, 20, 30, 40, ...

算法的功能是:Eliminates elements that satisfy a predicate from a given range without disturbing the order of the remaining elements and returning the end of a new range free of the specified value. 翻译过来就是说:在一个给定范围内删除满足一定条件的元素,在删除元素的过程中不改变剩余元素的位置,并...
Usestd::eraseandstd::removeFunctions to Remove Element From an Array in C++ Another scenario for this problem occurs when the given array is of typestd::vector. This time, we have the dynamic array features, and it’s more flexible to use a built-in function for element manipulations. ...

Removing is done by shifting the elements in the range in such a way that the elements that are not to be removed appear in the beginning of the range. Shifting is done bycopy assignment(until C++11)move assignment(since C++11).
Thestd::vector::resizefunction resizes the vector to contain the supplied number of elements. If the size is less than the vector’s size, all elements beyond the specified size are removed and destroyed. This can be used to remove elements from the end of a vector as follows, but it ...
