Here, from the Austrian National library where I was last summer photographing and having a wonderful time, is the last page of the Mozart -that Mozart ever wrote here. This is the "Lacrimosa, " and sort of breaking off--and he doesn't finish this particular movement.
这些都来自于奥地利国家图书馆,就是去年夏天我拍照的地方,在那我度过了快乐的时光,这是莫扎特安魂曲的最后一页,他曾写在这上面,这是《落泪之日》,还是半成品,他没来得及完成这个特殊的乐章
so I'm not in the library all the time,
所以我没有一直都待在图书馆里,
So, certainly the CS50 Library designed to be dynamic and, in fact, any time you call get string, we are, in fact, ; allocating a chunk of RAM but it's not coming from the stack; it's actually coming from this portion of memory called the heap.
所以,Cs50库是动态设计的,实际上,每次你调用GetSting时,我们分配一块内存,但它不是来自栈;,而是来自于叫做堆的,内存的一部分。
Heat up the library all the time.
要天天泡在图书馆里。
- Well -- and I'll fix this blue next time -- I'm first telling the compiler I need access to the standard io library because printf is declared there.
哦!--下次我把这个字体颜色改成蓝色的-,我先告诉编译器--我需要使用,标准输入输出库,因为printf在那个库里面申明的。
The standard library, that first line of code, it's not strictly necessary but any time you use a function, a tool that someone else wrote that lives in that so called library, you do need that include line as we'll see.
标准库函数--第一行代码,严格来说,不是每次都要写的,但是一旦你调用某个别人写,的函数,而这个函数又恰巧位于标准库里面,你就要像我们看到的这样,把它include进去。
