In C++, the erase function of a vector is used to delete one or a series of elements from the vector. It has two different usages:<\/p>\n

    \n
  1. Remove the element at the specified position using the iterator, and return an iterator pointing to the position after the deleted element. For example:<\/li>\n
  2. vector myVector = {1, 2, 3, 4, 5};
    \nauto it = myVector.erase(myVector.begin() + 2);
    \n\/\/ Erase the element at position 2, which is 3, and return an iterator pointing to 4
    \n\/\/ myVector becomes {1, 2, 4, 5}<\/li>\n
  3. Delete elements within the range [first, last) and return an iterator pointing to the position after the deleted elements. For example:<\/li>\n
  4. myVector vector = {1, 2, 3, 4, 5};
    \nauto it = myVector.erase(myVector.begin() + 1, myVector.begin() + 4);

    \n\/\/ myVector becomes {1, 5}<\/li>\n<\/ol>\n

    Note: After deleting elements using the erase function, all elements following the deleted element will automatically be shifted forward, so iterators may become invalidated and require careful handling.<\/p>\n","protected":false},"excerpt":{"rendered":"
