在C中从文本文件读取数据 [英] Reading data from text file in C

问题描述

我有一个文本文件，其中包含用空格分隔的单词.我想从文件中提取每个单词并将其存储.所以我打开了文件，但不确定如何将单词分配给char.

I have a text file which contains words separated by space. I want to take each word from the file and store it. So i have opened the file but am unsure how to assign the word to a char.

FILE *fp;
fp = fopen("file.txt", "r");
//then i want
char one = the first word in the file
char two = the second word in the file

FILE *fp;
fp = fopen("file.txt", "r");
//then i want
char one = the first word in the file
char two = the second word in the file

推荐答案

您不能将一个单词分配给char.您可以将一个字符分配给char-从而命名.您可以将一个单词分配给字符数组-例如s [128].

You cannot assign a word to a char. You can assign a single character to a char - hence the name. You can assign a word to an array of characters - such as s[128].

例如:

     char word[128];
     fscanf(fp, "%s", word);

请注意，在生产代码中，您不能仅使用静态大小的缓冲区，这将导致缓冲区溢出可利用代码.

Note, in production code you cannot just use statically sized buffer, this will lead to buffer overflow exploitable code.
