- scanf和sscanf之间的区别是什么？ssscanf


scanf从字符串中读取stdin，sscanf。 ssscanf不存在。

- printf和sprintf


printf打印到stdout，sprintf打印成字符串。

- open和fopen

open不存在。 fopen打开一个文件。

< blockquote class =post_quotes> - open and fopen

open不存在。 fopen打开一个文件。

打开是打开文件的UNIX系统调用。与ISO C无关。

你的C课本说什么？从

usenet的随机问题中学习C是一个坏主意，无法替代正确的学习。你浪费了你的时间和我们的时间。

SDZ <sa******@hotmail.com> scribbled the following:

scanf reads from stdin, sscanf from a string. ssscanf doesn''t exist.
- printf and sprintf
printf prints into stdout, sprintf into a string.
- open and fopen

open doesn''t exist. fopen opens a file.

open is an UNIX system call for opening files. Not related to ISO C.

What does your C textbook say? Learning C from random questions on
usenet is a bad idea and no substitute for proper study. You are wasting
your time and ours.
