2013年3月13日 · Yes, you! Right here! :-) { int b = 6; printf ("In block: %d %d\n", a, b); } printf ("Ex block: %d %d\n", a, b); return 0; } This has a b in scope at the point where you try to print it outside the block. It's not the b within the block but you'll find that out when the results are printed: In block: 5 6 Ex block: 5 42

2012年12月25日 · A block starts out life on the stack and, thus, a block's lifespan is only as long as the scope it is declared in. The body of a for() loop -- the body of the loop in the {}s -- is a scope in and of itself. Thus, your code is putting a reference to something on the stack [the block] into a variable in the surrounding scope [the language array].

C-BLOCK是我的中文说唱启蒙，从《老时光》《爆出口》《以下犯上》《淘金日记》一路走来，留下了太多脍炙人口的优秀作品，而小胖无疑也是三位中歌词最烫的那一个，Punchline更是信手拈来。

C-Block作为湖南HipHop的领头羊，此次在本地的开年演出自然要重视起来，Sup炸翻全场，C-Block也是演唱了最近新出的单曲和经典曲目。 三人合体演出以及各种活动虽然很多，但其实距离上一次三人共同合作发歌已经过去了大半年之久。

The easiest way I have found to block quote is to highlight the code and then to use the keyboard short-cut Ctrl + Shift + / to comment out that block. Works in most editors. Works in most editors. Hope that helps.

在介绍C-Block之前，我插播一个SUP。 SUP是长沙一个厂牌，目前旗下有C-Block，Ranzer，东别。Ranzer和东别也组了一个组合，叫X！GO。SUP的官方制作人是老道。 C-Block是SUP创始人之一，也是SUP旗下的组合，有三个人，大哥 大傻，二哥 刘聪，三弟 功夫胖。

2009年6月16日 · I want to launch a process from within my c program, but I don't want to wait for that program to finish. I can launch that process OK using system() but that always waits. Does anyone know of a 'non-blocking' version that will return as soon as the process has been started?

2011年12月1日 · To pick up on what @BRPocock said, lo these 8 years ago, it is possible to return a value from a “anonymous scope operator” / “lexical enclosure” — hence use a {} block as part of an expression — through the use of lambda functions.

2015年9月7日 · To comment a block of code (more than one line) in VS select code with ALT (alt+mouse or alt+shift+arrows), and then comment with Ctrl+K Ctrl+C. With one line code only you don't need ALT. So it's basically the same as with // comments, only ALT needs to be pressed while selecting code for more lines than one.

2011年10月29日 · The type of a block varies depending on its arguments and its return type. In the general case, block types are declared the same way function pointer types are, but replacing the * with a ^. One way to pass a block to a method is as follows: - (void)iterateWidgets:(void (^)(id, int))iteratorBlock; But as you can see, that's messy.
