Child class and Parent class

[MAhmed]

i'm calling function "output" from other classes to other classes as you can see below but i'm receiving errors on line 21,32,44
please checkout :-)

#include<iostream>

using namespace std;

class human
{
public:
	void output()
	{
		cout << "human" << endl;;
	}
};



class man :human
{
public:
	void output()
	{
		human::output;
		cout << "Man" << endl;
	}
};


class woman :human
{
public:
	void output()
	{
		man::output;
		cout << "Women" << endl;
	}
};



class chakka :man
{
public:
	void output()
	{
		human::output;
		cout << "chakka" << endl;
	}
};

void main()
{
	human h1;
	man m1;
	woman w1;
	chakka c1;

	h1.output();
	m1.output();
	w1.output();
	c1.output();
}

What exactly are the errors?

Do you know that when you don't specify the access specifier in classes you get private by default.

And in C++ main must be defined to return an int, and you should return an int from this function:

int main()
{

   return 0;
}

Lines 21,32,44: Those are not valid function calls. To call a function, you need ().

Line 32: woman does not inherit from man. You can't call man::output(). Did you mean human::output()?

Line 44: chakka inherits from man. Did you intend to call man::output()?
