	private:
		int a;
		int b;
        int c;
        int average;
	public:
		//member function declaration
		void readMarks(void);

//member function definitions
void Marks::readMarks(void)

    return sum;
}
int Marks::display(void)
{
    
	average = sum/3;
    return average;
}


//main function
int main()
{
	//declaring object
	Student s1;
	int add, average; //variable to store addition
	//take input
	s1.readMarks();
	//find addition
	add=num.display();
    //find average
	average=sum/3;
	//print numbers
   s1.printMarks();
	//print addition
	cout<<"Addition/sum= "<<sum<<endl;
    court<<" Average "<<average<<end1;
	
	return 0;
