function pointer

[enzo]

could anyone explain me why this compiles but doesn't work?

void foo()
{
cout << "Hallo" << endl;
}

class test
{
public:
test(void(*p_f)())
: m_f(p_f)
{
}

void
call()
{
*m_f;
}
private:
void
(*m_f)();
};

int main()
{
test a( &foo );
a.call();
return -1;
}

thanks

You forgot the brackets; call the function like this:

m_f();

....and your code will work.

This one too works..
(*m_f)();
