如何在C ++中的不同类中使用在一个类中定义的结构？

Question

I have this struct in a class, Class1 .:

static struct count {
    int member1;
    int member2;
    int member3;
} count1, count2, count3;

In Class1 , I will be incrementing all three of the count variables and using it again in Class2 in a separate file. How can I do this? Do I need to include Class1 in a header file?

Answer 1

the static variables scope is limited but lifetime is through out the program, if you have declare the count structure inside the class1 definition then you cant access this static count object in Class2 even though you include the file where Class2 has been defined. You have to make count structure global in the file and then can include the file to access it in Class2
