return in function in c++

[Shervan360]

Hello,

return type in DeleteFromQueue is int.
My code is not compiled. because in "else" I should return something.
How can I fix it?

Thanks

	int DeleteFromQueue()
	{
		if (!isEmpty())
		{
			int x = Queue[rear--];
			cout << "Deleted => " << x;
			return x;
		}
		else
		{
			cout << "Queue is EMPTY ! \n";
			// we need return something. because this code doesn't compile without return type.


		}
	}

bool DeleteFromQueue(int& returnedVal)
	{
		if (!isEmpty())
		{
			returnedVal = Queue[rear--];
			cout << "Deleted => " << returnedVal ;
                        return true;
		}
		else
		{
			cout << "Queue is EMPTY ! \n";
			return false;
		}
	}

You pass a reference to an int. If the function returns true, there was something in the queue and that value is now in the int you passed by reference.
