C++中的结构的使用

#include <iostream>using std::cout;using std::endl;//定义结构struct Box{double length;double width;double height;};double volume(const Box& aBox);int main(){Box box={70.0,60.0,40.0};double boxVolume=volume(box);cout << "Size of box is:"<<endl<< "length:"<<box.length<<endl<<"width:"<<box.width<<endl<<"height:"<<box.height<<endl;cout <<"Voluem of box is:"<<boxVolume<<endl;return 0;} //计算体积的函数double volume(const Box& box){return box.length*box.width*box.height;}
