// Benevolent Order of Programmer name structure 

struct bop {

    char fullname[strsize];      // real name

    char title[strsize];              // job title

    char bopname[strsize];     // secret BOP name

    int preference;                  // 0 = fullname, 1 = title, 2 = bopname

};

该程序创建一个由上述结构组成的小型数组，并将其初始化为适当的值。另外，该程序使用一个循环，让用户在下面的选项中进行选择：

a. display by name        b. display by title

c. display by bopname  d. display by preference

q. quit

注意，“display by preference”并不意味着显示成员的偏好，而是意味着根据成员的偏好来列出成员。例如，如果偏好号为1，则选择d将显示程序员的头衔。该程序的运行情况如下：

Benevolent Order Programmer Report 

a. display by name        b. display by title

c. display by bopname  d. display by preference

q. quit

Enter your choice: a

Wimp Macho

Raki Rhodes

Celia Laiter

Hoppy Hipman

Pat Hand

Next choice: d

Wimp Macho

Junior Programmer

MIPS 

Analyst Trainee

LOOPY

Next choice: q

Bye!
