不使用while，for，if等实现加法

不使用if， while，for，switch等实现从1到10的加法

解：这里使用静态函数和静态变量实现，利用类似的方法也能够实现从1打印到1000

class TheSum{
public:
	TheSum();
	static int GetSum();
private:
	static int N;
	static int sum;
};

int TheSum::N=0;
int TheSum::sum=0;

int TheSum::GetSum()
{
	return sum;
}

TheSum::TheSum()
{
	N++;
	sum+=N;
}

int caculateSum(int n)
{
	TheSum *p=new TheSum[n];
	int sum=TheSum::GetSum();
	delete p;
	return sum;
}

#define MMySizeOf(value)  ((char *)(&value+1) - (char *)&value)

void main()
{
	cout<<caculateSum(10)<<endl;
}
