C++ Erase vector element by value rather than by position? vector lt;int gt; myVector; and lets say the values in the vector are this (in this order): 5 9 2 8 0 7 If I wanted to erase the element that contains the value of "8", I think I would do this:
Removing item from vector while iterating? - Stack Overflow The most readable way I've done this in the past is to use std::vector::erase combined with std::remove_if In the example below, I use this combination to remove any number less than 10 from a vector
c++ - Vector erase iterator - Stack Overflow 3 Because the method erase in vector return the next iterator of the passed iterator I will give example of how to remove element in vector when iterating
How can you erase elements from a vector while iterating? I want to clear a element from a vector using the erase method But the problem here is that the element is not guaranteed to occur only once in the vector It may be present multiple times and I n
Remove elements of a vector inside the loop - Stack Overflow std::vector::erase(iterator) removes a single element pointed to by the iterator In your example, it will attempt to remove the element pointed to by the iterator returned by std::remove_if -- which is a pass-the-end iterator so this is almost certainly incorrect (and will cause a crash)
Does vector::erase() on a vector of object pointers destroy the object . . . 54 I have a vector of pointers to objects I need to remove an element from the vector and place that element in another list I read that erase can be used to remove the object from the vector, but I also read that it calls the objects destructor before doing so I need to know whether or not erasing the object will destroy it as well
Difference between std::remove and erase for vector? I am aware of the different behavior for std::vector between erase and std::remove where the first physically removes an element from the vector, reducing size, and the other just moves an element leaving the capacity the same
c++ - Erasing element from Vector - Stack Overflow #include <vector> #include <algorithm> std::vector<int> v; v erase(std::remove(v begin(), v end(), 12), v end()); remove reorders the elements so that all the erasees are at the end and returns an iterator to the beginning of the erasee range, and erase actually removes the elements from the container This is as efficient as you can get with a contiguous-storage container like vector, especially if you have multiple elements of the same value that all get erased in one wash
Delete all items from a c++ std::vector - Stack Overflow I'm trying to delete everything from a std::vector by using the following code vector erase( vector begin(), vector end() ); but it doesn't work Update: Doesn't clear destruct the elements held b
