静态成员函数只能访问静态数据成员和其他静态成员函数。它们不能访问非静态成员,因为非静态成员与特定的类对象相关联,而静态成员函数则与类本身相关联。 通过遵循这些指导原则,可以避免在C++中遇到“cannot declare member function to have static linkage”的错误,并正确地使用静态成员函数。
英文解释:ifyou declare a method to bestaticinyour .cc file. The reasonisthatstaticmeans something different inside .cc files thaninclassdeclarations Itisreally stupid, but the keywordstatichas three different meanings. In the .cc file, thestatickeyword means that the function isn't visible to an...
静态成员函数编译时出现static成员"Cannot declare member function ...to have static linkage"错误 解决方案 在.cpp文件中去掉static关键字 static的用法有好几种,在类中成员函数的声明使用static关键字则是规定说该成员函数为该类所有实例所共享也就是所谓的"one-per-class",而在.cpp文件中使用static关键字的作用...
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 But without an object, a call to length makes no sense: ...
