But remove the Kevin Everett sat rase () is no problem, is can't use? Konjac thank leaders answer

After it is deleted, it is there something in the iterator? Sure I don't think so, you for loop still use it++, is bound to go wrong, or use the erase places it++, and remove the for loop on the operation
