在class computer的析构函数中的三个if语句中的delete会有警告提示（delete called on 'VIDEOCARD' that is abstract but has non-virtual destructor [-Wdelete-non-virtual-dtor]），void test1（）中的delete却没有报警。在vs2019中4个delete均没有警告提示，请问是不是我的vscode配置有问题，还请各位指点一下，我应该如何修改vscode的配置

已经解决了，在相应的类中加入虚析构函数就没有报警，最近刚开始学类，对类的语法还不是很熟悉。但是不明白为什么vscode会报警，而vs2019不报警，希望知道原因的的哥哥姐姐看到这里帮我解答一下，
