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,在类加载时就会分配内...

在C++编程中,遇到“invalid use of non-static data member”错误通常意味着你在不恰当的上下文中使用了非静态数据成员。下面我将详细解释这个问题及其解决方法。 1. 什么是“non-static data member”? 在C++中,类的成员变量分为静态成员变量(static member variable)和非静态成员变量(non-static member variable)...
*pFunction)();//简单的调用 } int main() { c d; d.fun(temp::foo); return 0; } 在windows下可以编译成功并正常运行,而在Linux下则会出现下面报错 error: invalid use of non-static member function 问题出在编译器不认可传递参数是non-static的类成员函数指针,也就是代码块中的d.fun(temp::foo...
main()is not a member function. If the function must be non-static, an object of the class type is required. For example: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 #include <iostream>#include <thread>#include <chrono>#include <ctime>structschedu...
