Trying to compile some code and I keep getting an error that says " 'myString& operator=(const myString&)' must be a nonstatic member function" This is my namelist.cpp myString& operator=(const myString& string) { if(this = &string) return *this; data = new char[strlen(string.data...

在另一个贴子已经回答了，类外定义成员函数时，返回类型写在前面，再写类名::。参数类型必须和声明一致，不能乱加const。
Qt开发,一行代码报错: reference to non-static member function must be called; did you mean to call it with no arguments? 代码: if(tbxD.toPlainText().trimmed().length==0) { ... } if(tbxM.toPlainText().trimmed().length==0) { ... } if(tbxS.toPlainText().trimmed().length==0)...
使用sort函数的时候因为自己要定义compare,但是会报错error: reference to non-static member function must be called。 解决方案: compare函数前面加个static就可。这题是力扣205题,题源: 力扣leetcode-cn.com/problems/isomorphic-strings/ classSolution{public:structST{charch1;charch2;};staticboolcmp1(struc...
意思是你访问某个类的某个非静态成员的时候没有指定对象。正确引用非静态数据成员的语法是： 对象名.成员名 或者 对象指针->成员名 我估计你大概是定义了一个静态成员函数，并且在该函数内部引用了一个非静态成员，但是你引用的时候没有指定对象，所以编译器报错。
是因为此时智能指针m_p的处理函数是一个类中的成员函数unlock,且传给智能指针的也是一个函数指针,但是要调用成员函数的话,是需要通过类的实例对象来进行的,而在智能指针中调用的时候,是没有这个实例对象存在的,结果就挂了。 参考:http://stackoverflow.com/questions/22513680/non-static-member-function-must-be-...
之前写多线程函数getData 在main中调用时, std:thread t(getData) getData的实现是 void getData(){ } 但是如果是在一个类的构造方法中调用时,这样写就会报错,reference to non-static member function must be called 解决方法是,在类的头文件中将getData设置为静态方法...
题目很简单,利用lowbit操作计算一个数二进制1的个数,接着自定义比较函数进行排序即可,但是C++在类中自定义比较函数不能简单地定义为成员函数,需要定义为静态成员函数。 具体看:Reference to non-static member function must be called
