Now in this case, it's clear that I'm not only saying this function takes an input, I also have to give that input a name.
在这种情况,很清楚的,我不只是说明这个函数有一个输入,我还要给那个输入一个名字。
So one of the things I want you to notice here is that testing and debugging are not the same thing. When we test, we compare an input output pair to a specification.
这里我想大家注意的一件事,就是测试和调试是不同的两件事情,我们测试的时候,我们把输入输出,跟程序的规格说明书对比下。
It's just an input to a function, the thing inside parentheses.
圆括号里面的东西,只是一个函数的输入。
If you think about receptor ligand system as an input into the cell.
如果将受体-配体系统看作,细胞的一种输入机制的话
There're 2 individuals who're going to supply an input to a joint project.
有两个实体共同完成一个协作项目
Maybe that's just an illusion created by the fact that I'm getting this visual input from my body .
也许那种想法就是一个错觉,因为通过视觉我知道,肉体有位置,随之假设灵魂也有位置
get back to the initial point is going to require some input from outside, like heat or extra work or extra heat or something because you've done an irreversible process.
如果要逆转它,回到初始点,就需要外界的投入,比如额外的功,额外的热量等等,因为你进行了一个不可逆过程。
So, this is what goes on in an electrolysis cell, and it works thanks to input energy from a power supply shown here.
所以,这是在一个电化学电池中发生的,它是靠输入的能量工作的,从和这个类似的电源输出的能量。
An argument or a parameter is an input to a function.
参数或参量是一个函数的输入。
Computing square root. I'm going to capture it in a piece of code, I'm going to be able to refer to it by a name, and I'm going to suppress the details, meaning inside of that computation, you don't need to know what it does. You just need to know, if I give it the right kind of input, it'll give me back an input that satisfies the contract that I set up.
比如计算平方根,我会用一段代码来说明,我将给它命名,并且忽略细节,意思就是在这一段计算过程中,你不用知道它做了什么,你只需知道,如果我进行了正确的输入,它将会给我符合条件的输出。
I'm taking an input.
我获得一个输入。
So the running time of the problem where the input is T of size N as expressed here formulaically, T of N, the running time of an algorithm, given an input of size N. You know what?
因此一个输入为N的问题的运行时间,在这儿的公式表示为,如果输入为N,那么此算法的运行时间,是多少呢?
I have a sequence of commands; I've got an assignment statement, I've got another assignment statement, I've got a print statement, I've got an input statement, which we'll come back to in a second.
这是一系列的命令;,我有了一个赋值声明,然后是另外一个赋值声明,还有一个print声明,然后是一个input声明,我们稍后会讲讲这个生命。
It ran through that sequence of instructions, in particular it bound x to the value three, x and then it took x times x, got the value of x multipied by x, which of course is nine, bound that to the value of x, and then it printed out the value, and now it's sitting here waiting for an input.
程序按照指令的顺序去执行的,首先是把x和3这个值进行了绑定,然后把x乘以,得到了x乘以x的值,当然也就是9了,然后把x和这个值进行了绑定,然后显示出这个值,然后就等待输入。
I'm much better having an exception get handled at the time of input than to let that prop -- that value rather propagate through a whole bunch of code until eventually it hits an error 17 calls later, and you have no clue where it came from.
不是我期望的格式,这时我最好有一个异常处理,而不是让其传下去,这个值传到代码的整个分支,最终会导致一个错误17调用的发生,并且你不知道这个错误是哪里来的。
It then should take an argument or parameter if you want your function to take input.
然后它必须携带一个参数或参量,如果你想要你的函数获得一个输入。
But when you start writing programs, especially when we get to web-based stuff where you want -- to check the user's input -- is it valid, is it an email address, -- and all these different scenarios -- it's actually often useful to be able to just enumerate them or rattle them off using this switching construct instead.
但是当你看是写程序时,特别是当我们,使用基于网络的东西,你想要,检查用户的输入-,它是合法的吗?它是不是一个电子邮箱地址?,所有的这些场景-,实际上它常常是有用的,当你用枚举结构列举它们,或者用它来快速地来说出它们。
So input is an int called F, print out to the screen or your piece of paper the value of C. Odds are you only need two, maybe three lines of code for this, but the goal ultimately will be try it on your own.
所以输入是一个int类型的F,在你的屏幕上,或你们的纸上打印出C的数值,可能你们需要两行或者三行的代码,但是最终的目标需要你自己独自尝试。
We own our own phone number, that allows you to input key strokes like you would any system and this is an example of what we call CS50 Voice.
我们都有电话号码,这就让我们可以输入任意的数字,然后这是CS50,Voice的一个例子。
And then, if I want to find out if something's there, I do the same thing. But notice now, hash is converting the input into an integer.
然后,我想查找出某些元素是否在列表中,我做同样的事,但是现在注意,哈希是将输入转化成一个整数,所以,其思想是什么?
Go ahead and implement with the person next to you a program that takes as input from the user an integer called F and prints out the answer of the Celsius equivalent.
继续和你旁边的人执行程序,取来自用户的整数F作为输入,然后打印出与之等价的摄氏温度的答案。
