int main(int argc, char* args[]) { Base* b = new Sub(); delete b; return 0; } 由于基类Base的析构函数没有声明为virtual,当对象被销毁时,只会调用基类的析构函数,不会调用派生类Sub的析构函数,导致内存泄漏。例外: NoCopyable、NoMovable这种没有任何行为,仅仅用来做标识符的类,可以不定义虚析...
注:以上数据排除了cppcheck35个低价值报错,这里排除的cppcheck35个报错都是基本数据类型的new和delete不匹配(如char* p=new char[100];delete p;)虽然这种写法不规范,但由于实际上不会造成内存泄漏,很多项目不会对此进行修复。 从报错数量和准确率来看: ...
