Pointing* aPointer;

public:
Example(Pointing* point){
aPointer = point;
}

int acessor(){
return aPointer->exampleMethod();
}


};


when compiling i receive an error anyone have any ideas

推荐答案

你需要告诉我们错误是什么。我们无法读懂你的想法。然后，你的访问者（原文如此）应首先检查指针是否为空。但是，所有这些都应该编译。我不明白为什么这不会编译，除非Pointer没有'exampleMethod'。

You need to tell us what the error is. We can't read your mind. Then, your acessor (sic) should check first if the pointer is null. But, all of that should compile. I can't see why this would not compile, unless Pointer does not have an 'exampleMethod'.
