Here, foo and bar are both strings. Now you can call member functions (such as the length function) by using the object name and the dot operator: size_t len = foo.length();// get the length of the foo string Bu
@文心快码error: call to non-static member function without an object argument 文心快码 错误信息解释error: call to non-static member function without an object argument 这个错误信息表明,你试图以非静态方式调用一个非静态成员函数,但是没有提供调用该函数所需的对象实例。
call to non-static member function without an object argument 调用不带对象的非静态成员函数。 原因:类没有实例化,就调用了其中的成员函数。比如直接【类::成员函数】 解决方案:1.在成员函数前加static,变成静态成员函数,静态成员函数可以不用实例化,直接【类::成员函数】调用; 2.在调用成员函数前,先实例化...
error: call to non-static member function without an object argument 1.在c++中,如果一个类中有个静态方法,那么这个静态方法中调用的也是静态方法 2.在c++中,一个类的普通函数,既可以调用非静态方法,也可以调用静态方法 例如: DriverOfNet类中有个静态函数 netCallBackData 还有一个非静态函数 ConvertToHex ...
以call to non static member function without an object argument为例,这种特殊的函数调用方式可能会导致程序出现问题。例如,在使用函数指针时,如果没有进行正确的初始化,可能会导致程序崩溃。因此,我们需要确保在调用非静态成员函数时,使用正确的函数指针进行调用,从而避免出现问题。
