	for(int i = 0; i < malen; i++)
		for(int j = i; j < malen; j++)
			if(male[i] > male[j])

	for(int i = 0; i < malen; i++)
		std::cout << std::fixed << std::setprecision(2) << male[i] << " ";
	for(int i = 0; i < femalen; i++)
		std::cout << std::fixed << std::setprecision(2) << female[i] << " ";
	cout << endl;
	 
	printf("
");
	return 0;
}

std::

其实没什么用，要是不要std::
就必须写上

using namespace std;

struct 是一个结构体
有一个int类型变量
和一个string类型变量。
