"By suddenly having an actual mechanism to value these systems in dollars, it gives you a potentially very large new mechanism for countering the other financial and economic arguments."
VOA: special.2011.05.10
You don't have to declare a special variable for it if you don't care about its actual value.
你并不需要为它声明一个特定的变量,如果你不关心它的实际值。
In other words, lower the amount insured below the actual value of the house to prevent moral hazard.
换句话说,将房屋的保险价值低估于其实际价值,以此来防范道德风险。
Well, what's the actual value?
准确值是多少?
We have a pointer to the location in memory that contains the actual value, which itself might be a bunch of pointers, and we have a pointer to the actual-- sorry, a pointer the value and we have a pointer to the next element in the list. All right?
包含实际值的地址,可能实际值,也是一系列指针,这里还有指向实际,抱歉,指向下一个元素的指针,我们来整理下?
Now, this is not the nicest way to do it but it'll work. I can look at the type of the value of base and compare it to the type of an actual float and see, are they the same?
这不是最好的办法但它确实有用,我可以得到底的值的类型然后,和一个真的浮点数的类型比比,看他们是不是一样?
And again, a related problem that people run into is side-effects. You call a function and it returns a value, but maybe it, on purpose or on accident, modifies one of the actual parameters.
另外,一个人们常碰到的相关问题,就是副作用,你调用一个函数它返回一个值,但是故意或者无意的,它可能会修改一个实参的值。
