How to declare a pointer to a member function?
Ans: Suppose, I wish to declare a pointer to a member function that receives an int and returns an int. I will have to declare it as int ( A::* ) ( int ). Following is an example.
#include
class A
{
public :
int fun ( int f )
{
cout << "in fun\n" ;
return f * f ;
}
} ;
typedef int ( A:: *pfun ) ( int ) ;
void main( )
{
pfun p = A::fun ;
A a ;
int s = ( a.*p ) ( 6 ) ;
cout <<>
}
