关于struct一些操作

第一个程序，struct的基本使用

#include "stdafx.h"

#include <iostream>

using namespace std;

struct inflatable

{

char name[20];

float volume;

double price;

}; //注意，这个声明后面有个分号！

int main(int argc, char* argv[])

{

inflatable quest=

{

"Clorious Gloria",//name value

1.88,//volume value

29.99//price value

};

inflatable pal=

{

"Audacious Arthur",

3.12,

32.99

};

cout<<"Expand your quest list with "<<quest.name;

cout<<" and "<<pal.name<<"!\n";

cout<<"You can hava both for $";

cout<< quest.price+pal.price<<"!\n";

return 0;

}

第二个程序：使用new创建一个未命名的结构，并演示两种访问结构成员的指针表示法。

#include "stdafx.h"

#include <iostream>

using namespace std;

struct inflatable

{

char name[20];

float volume;

double price;

};

int main(int argc, char* argv[])

{

inflatable * ps=new inflatable; //allot memory for structure

cout<<"Enter name of inflatable item: ";

cin.get(ps->name,20); //method 1 for member access

cout<<"Enter volume in cubic feet: ";

cin>>(*ps).volume; //method 2 for member access

cout<<"Enter price: $";

cin>>ps->price;

cout<<"Name: "<<(*ps).name<<endl;//method2

cout<<"Volume:"<<ps->volume<<" cubic feet\n";//method 1

cout<<"Price: $"<<ps->price<<endl;

delete ps;//free memory used by structure
