[mobydick]

问题：有A、B两架飞机，A需要2名驾驶员，可载30人；B需要1名驾驶员，可载20人。现有A20架，B40架，驾驶员50名。问，分别用多少架A、B才能使所载人员最多。（A、B驾驶员可通用）

能不能不用循环解决这一道题。

class plane()

private pilot;

{

plane A = new plane();
plane B = new plane();

A.setPilot = 2;
A.setCarry = 30;
B.setPilot = 1;

for(x = 1; x < 20; x++)
for(y = 1; y < 40; y++)
{
n = x*A.getPilot + y*B.getPilot; //number of pilot

if(n <= 50)

if(maxC.c < m)
{
maxC.p = n;
maxC.c = m;
}
}
}
Console.WriteLine(maxC.p+"\r\n"+maxC.c);
}
