I'm trying to declare a static object of a class A that I wrote in a different class B, like this:
class A // just an example
{
int x;
public:
A(){ x = 4; }
int getX() { return x; }
};
class B
{
static A obj1; // <- Problem happens here
public:
static void start();
};
int main()
{
B::start();
}
void B::start()
{
int x = obj1.getX();
}
What I want to achieve is to get int x
in B::start()
to equal int x
in class A
(4).
I tried googling all this for the past hour and all I understood was that C++ doesn't allow static objects' declarations. Is that correct?
If so, here's my question. How can I get the same result? What are my available workarounds? Keeping in mind that the rest of my code depends on the functions in class B to be static.
Error
error LNK2001: unresolved external symbol "private: static class A B::obj1"
Thanks!
You should initialize static var
, the code:
class A // just an example
{
int x;
public:
A(){ x = 4; }
int getX() { return x; }
};
class B
{
static A obj1; // <- Problem happens here
public:
static void start();
};
A B::obj1; // init static var
int main()
{
B::start();
}
void B::start()
{
int x = obj1.getX();
}
