It is the number one followed by one-hundred zeros.

Text is where the zeros and ones that compose your file are actually stored.
文本是那些二进制,构成的存储文件。
The bits, the zeros and ones that compose the library are actually - in that file called cs50.c but those bits live or-- even that's a white lie.
这些构成该库的比特--0啊1啊,却是在cs50,c文件里,这些源代码-,可以说是根本不存在。
And so this, in fact, when you say your computer stores information as zeros and ones, A you've just typed the capital letter A, that's all that's going on inside.
事实上,当你说电脑以这些0与1进行信息存储时,你已经键入了大写字母,那就是在计算机内部发生的过程。
Meanwhile, the number zero is. Alright, it's all zeros 0 so I'll--just for consistency, use four of them here, but that's just an aesthetic.
同时,数字0呢,自然,全部是,只是为了一致性,我采用四个,当然仅仅是为了美感。
And just like in the decimal system, 0 as many zeros on the left that you want.
就像在十进制中,任意放置。
So the fact that I'm erasing it does not mean that the computer erased that memory or over wrote those values with all zeros.
事实上,我清除它的意思,不是说计算机把内存清除,或者用0覆盖这些值。
The so called binary system, 1 these zeros and ones that you'd probably have some vague sense underlie all computers today actually reduced to the exact same grade school kind of math and system except with computers, 1 because it's a lot easier to use just two digits, zero and one.
所谓的二进制就是,你觉得模糊的0与,在电脑上计算,事实上可以简化为跟小学数学一样,只是在电脑上计算而已,因为它更容易,仅仅使用两个数字,0与。
> But if you actually do the math, those zeros and ones translate to an ASCII character which is D which is gonna be a 65, 66, 67, 68 would be the letter D.
>,你们自己算算看,把这些0和1转换成D对应的ASCII码,那么就是,65,66,67,68,对,68对应于“D“
But the take away for now is that if you don't clue -lcs50, -- you get some mention -- some error message -- about "undefined symbol," and that should be your clue that, "Oh it's undefined in that I haven't told the compiler that I want to link in these zeros and ones."
但现在如果你删除“-lcs50“,你们会得到一些提示--一些错误信息-,像“未定义的符号“,这可以为你提过线索,“这个没有被定义,我没有告诉编译器,把想把这个与“1“和“0“建立连接,“
