从C中输入文件扫描，直到达到一定的字符（＃）？ [英] scanning from an input file in C until reaching a certain character (#)?

问题描述

简单问题：

如果我有，看起来很像输入文件中的一行：

If i have a line in an input file that looks looks like:

Hello#Great#Day#Today

我怎么能在每一个字扫描单独作为自己的阵列，换句话说告诉C当它到达＃字符以停止扫描，然后在循环的下一次迭代去扫描下一个字作为一个单独的数组？

how can I scan in each word individually as its own array, in other words tell C to stop scanning when it reaches the # character and then go in the next iteration of the loop to scan the next word as a separate array?

推荐答案

这是假设你是通过标准输入读书。绝对看一看@Whoz踢启动的方法，以及（非常类似于这样）。

This is assuming you are reading through stdin. Definitely take a look at @Whoz kick start approach as well (very similar to this).

你所想要做的就是创建一个动态数组，并通过标准输入每读取一个字节填充它。那么你想创建字符指针数组，将指向第一个字符在每一个字，在这里你定义一个字像以前一样每一个字符一个'＃'字符（分隔符）。然后，您将通过字符数组迭代，并填充每个单词的第一个字符的内存地址字符指针数组。

What you would want to do is create a dynamic array and populate it with every byte read through stdin. You would then want to create an array of character pointers that will point to the first character in every "word", where you define a word as every character before a '#' character (delimiter). You would then iterate through that array of characters and populate the array of character pointers with the memory addresses of the first character in each word.
