Thread: Need some help.

I need some help on a simple program that I can't get to work. Here is the code that I have so far:

Code:

class testClass
{
public:
	int sum();
		//Postcondition: Returns the sum of the
		//				 private data numbers
	void print() const;
		//Prints the values of the private data
		//members
	testClass();
		//defualt constructor
		//Postcondition: x =0; y =0
	testClass(int a, int b);
		//constructor with parameters
		//Initializes the private data members to the
		//values specified by the parameters.
		//Postcondition: x = a; y= b
private:
	int x;
	int y;
};

#include <iostream>

using namespace std;

testClass::testClass()
{
	x = 0;
	y = 0;
}

testClass::testClass(int a, int b)
{
	x = a;
	y = b;
}

void testClass::print() const
{
	cout << "The sum of " << x << " and " << y << " is " << sum() << endl;		
}

int testClass::sum()
{
	return (x + y);	
}

// Main

int main()
{
	int a=0;
	int b=0;

	testClass t;
	testClass();
	t.print();
	cout << endl << "Input 2 integers: ";
	cin >> a >> b;

	testClass(a,b);

	cout << endl << t.sum() << endl;

	return 0;
}

Any help will be greatly appreciated.

My problem is that I can not get the constructor with parameters to initialize the values of x and y to the values of a and b.

Maybe I am tired, but I'm kinda confused on how to fix it. I tried messing around with what you put in your reply, but I still can't get the non-default constructor to work. The values for x and y still remain to be 0.

n/m i got it working...thanks
