Invalid variable value
I don't understand why this app gives output other than 0. Compiled and tested on 2 different linux. I am not sure if this is my misunderstanding of c++ or some kind of bug. Can anyone elucidate what is going on there?
Code:
class A
{
public:
class B
{
public:
B(int f){}
};
B b=0;
A(bool loop){}
};
class O : public A
{
public:
int problem=0;
using A::A;
};
class Z
{
public:
O o(true);
Z()
{
Log(S+o.problem+'\n');
Exit();
}
};
void InitPre()
{
EE_INIT();
App.flag=APP_HIDDEN;
}
bool Init()
{
Z *z=new Z;
return true;
}
void Shut(){}
bool Update(){}
void Draw(){}

RE: Invalid variable value
You call " O o(true);" constructor, it's from A class, not from O, so " problem" is not initialized. If you use this:
Code:
class Z
{
public:
O o;//(true);
Z()
{
...
It will be OK.

RE: Invalid variable value
I would write the code this way:
Code:
class A
{
class B
{
B(int f){}
};
B b=0;
A(bool loop){}
};
class O : A
{
int problem=0;
O(bool loop) : A(loop) {}
};
class Z
{
O o(true);
Z()
{
Exit(o.problem);
}
};
void InitPre()
{
EE_INIT();
Z z;
App.flag=APP_EXIT_IMMEDIATELY;
}
bool Init()
{
return false;
}
void Shut(){}
bool Update(){return false;}
void Draw(){}
BTW. In EE Code Editor 'class' is already public.
