因此,编译器无法确定应该访问哪个实例的非静态成员,这会导致编译错误,即“invalid use of member in static member function”。 给出解决“invalid use of member in static member function”错误的方法 要解决这个问题,有几种方法: 将非静态成员改为静态成员:如果逻辑上允许

error: invalid use of non-static member function ‘bool MyClass::cmp(int, int)’ 看报错信息的字面意思似乎是:因为 cmp 是非static函数,那如果把 cmp 定义成static呢?果然编译ok。这是为啥? 这就涉及到第一个问题:static成员函数和非static成员函数有什么区别? 1.类的static成员属于类本身,在类加载时就会...
「 C++ 11」std::thread “invalid use of non-static member function“问题处理,因为静态函数不与类的任何对象相关联。因此,我们可以直接将类的静态

C++编译错误”invalid use of nonstatic data member”通常是由于以下两种原因造成的:尝试在非静态上下文中使用静态数据成员:在C++中,静态成员属于类本身,而非类的某个特定对象。因此,静态成员应通过类名来访问。如果在对象实例的上下文中尝试访问静态成员,编译器会抛出此错误。解决方法:...
