Misunderstanding function pointer - passing it as an argument
- by Stef
I want to pass a member function of class A to class B via a function pointer as argument. Please advise whether this road is leading somewhere and help me fill the pothole.
#include <iostream>
using namespace std;
class A{
public:
int dosomeA(int x){
cout<< "doing some A to "<<x <<endl;
return(0);
}
};
class B{
public:
B(int (*ptr)(int)){ptr(0);};
};
int main()
{
A a;
int (*APtr)(int)=&A::dosomeA;
B b(APtr);
return 0;
}
This brilliant piece of code leaves me with the compiler error:
cannot convert int (A::*)(int)' toint (*)(int)' in initialization
Firstly I want it to compile.
Secondly I don't want dosomeA to be STATIC.
