[source in ebook] scanf-temp DL : 0: 键盘缓冲区残余信息问题 scanf(" c",&c) 这句不能正常接收字符,什么原因呢？我们用 printf("c= d\n",c) 将C用int表示出来，启用printf("c= d\n",c) 这一句，看看scanf()函数赋给C到底是什么，结果是c=10 ,ASCII值为10是什么？换行即\n.对了，我们每击打一下"Enter"键，向键盘缓冲区发去一个“回车”(\r),一个“换行"(\n),在这里 \r被scanf()函数处理掉了（姑且这么认为吧^_^），而\n被scanf()函数“错误”地赋给了c.解决办法：可以在两个scanf()函数之后加个fflush(stdin) ，还有加getch() , getchar()也可以，但是要视具体scanf()语句加那个，这里就不分析了，读者自己去摸索吧。但是加fflush(stdin) 不管什么情况都可行。 -Keyboard buffer residual information problems scanf (" c" , & c) sentence does not receive characters, what causes it? We use printf (" c = d \ n" , c) int represented by the C Enable printf (" c = d \ n" , c) this one, see scanf () function is assigned to C What in the end, the result is c = 10, ASCII value of 10 is what? Newline is \ n. Yes, we look at every hit " Enter" key, the keyboard buffer sent a " carriage return" (\ r), a " newline" (\ n), where \ r is scanf ( ) function handles out (let so that it ^ _ ^), and \ n is scanf () function " error" to assign a c. Solution: can two scanf () function then add fflush (stdin) , as well as add getch (), getchar () can, but depending on the specific scanf () statement added that, there is not analyzed, the reader to explore it. But add fflush (stdin) matter what conditions are feasible.

[source in ebook] yaolog DL : 0: 就C++而言，不少程序员只是简单地用printf来输出日志，或者临时写个日志类，log4cpp等比较“重型”的日志库的使用率反而并不怎么高（至少从我经历的项目而言）。也许是不想为不需要的功能付出额外的学习成本，但无论如何，对于通用类别的工具采取临时手写的方式来应付，从长远考虑，在功能性和健壮性方面是得不偿失的。写这个日志类(yaolog)的最初的想法只是为了实现“输出到文件的带有时间信息的printf”，后来历经不同项目需求的“拷问”，借鉴和引用了很多开源代码（在此对那些作者表示感谢），就成了现在这个样子-C++ is concerned, many programmers simply use printf to output logs, or temporary write a log type, log4cpp other more heavy usage log library but not how high (at least my experience of project Introduction). Perhaps not want to pay the extra cost for unwanted features to learn, but in any case, for the general class of tools to take temporary handwriting way to cope with the long term in terms of functionality and robustness is worth the candle. Write this log classes (yaolog) The initial idea is to achieve with the time information is output to a file printf , and later through the different needs of the project, torture , reference and cite a lot of open source code (in this case those of thanked), it becomes like this now

[source in ebook] C语言中printf的使用 DL : 0: printf()函数是式样化输出函数, 一般用于向准则输出设备按规定式样输出消息。正在编写步骤时经常会用到此函数。printf()函数的挪用式样为: printf("<式样化字符串>"，<参量表>)；(The printf () function is a stylized output function, which is generally used to output messages to a standard output device in a prescribed pattern. You are often used to this function when you are writing the steps. The misappropriation of the printf () function is as follows: Printf ("< stylized string >", < parametric Table >);)
