Erase() function to remove a single and specific element from a vectorerase() method can be used to remove a single element by passing the position or with the help of index. Here we have discussed all the methods.Note: When we remove a single element, the iterator passed must be derefe...

it is not erasing the specific vector Code: typedef std::vector < int > nodeList; nodeList temp; nodeList neighborX = this->computeNeighbors(x); for (nodeList::iterator iter = neighborX.begin(); iter != neighborX.end(); ++iter) { int y = *iter; temp = neighborX; neighborX....

myVector.erase(std::remove_if(myVector.begin(), myVector.end(), [&uniqueSet](const int& val) { return !uniqueSet.insert(val).second; }), myVector.end()); The loop condition checks if the insertion into the unordered set is successful. If an element already exists, indicating a ...

The iteratorfirstdoes not need to be dereferenceable iffirst==last: erasing an empty range is a no-op. Parameters pos-iterator to the element to remove first, last-range of elements to remove Type requirements - Tmust meet the requirements ofMoveAssignable. ...

This post will discuss how to get an iterator to the n’th element of a vector in C++. 1. Using std::advance function To get an iterator starting from the n’th item, the idea is to construct an iterator pointing to the beginning of the input vector and call the standard algorithm ...
