第六章第四题 结构体和选择结构的应用

#include <iostream>
const int strsize = 20;  // 对常量应用const；
struct bop
{
char fullname[strsize];
char title[strsize];
char bopname[strsize];
int preference;
};
using namespace std;
int main()
{
cout << "Benevolent Order of programmers Report \n"
<< "a. display by name           b.display by title\n"
<< "c.display by bopname        d.display by preference\n"
<< "q. quit\n ";
char ch;
bop member[5] = {  // 创建五个这样的结构体
{"Wimp Macho","English Teacher","DEMON",0},  // 只写一组当测试用；
};
cout << "Enter your choice :";
while (cin >> ch && ch != 'q')
{
switch (ch)
{
case'a':
for (int i = 0; i < 1; i++)
cout << member[i].fullname << endl;   // 数组储存更多元素，站更多字节；
break;
default:
break;
}
}
return 0;
}
