A.Generator函数,又称生成器函数
B.声明Generator函数的关键字是:function*
C.Generator函数执行后得到的一个生成器
D.使用return语句使Generator函数暂停执行,直到next方法的调用
g) 一个指向函数的指针,该函数有一个整型
参数并返回一个整型数(A pointer to a function that
takes an integer as an argument and returns an

小麦的生产函数为q=100K0.8L0.2。
(1)开始时资本投入为4单位,劳动投入为49单位,请证明劳动和资本的边际产量都下降。
(2)该生产函数显示的规模报酬是递增、递减,还是不变?
In Example 6.3,wheat is produced according to the production function g= 100(K0.8L0.2).
a. Beginning with a capital input of4 and a labor input of 49,show that the marginal product of labor and the marginal product of capital are both decreasing.
b. Does this production function exhibit increasing, decreasing, or constant returns to scale?
