c - 将文本文件中的单词保存到 c 中的两个表中

Question

我有一个文本文件，每行有两个单词，我想读取它并将每行的第一个单词保存在第一个[numberoflinesinfile][maxcharacterperword]类型的表中，第二个类似表中的一个。其中表的每个条目都是一个字符。

Answer 1

一个非常简单的解决方案:

#include <stdio.h>
#include <string.h>

#define FILE_NAME "myFile.txt"

int main () {

    // Open file for reading:
    FILE *file;
    file = fopen(FILE_NAME, "r");

    // Some counters:
    int i = 0;
    int j;

    // Two dimensional arrays: 
    char first[10][30];
    char second[10][30];

    // Loop through file: 
    while ( fscanf(file, "%s", first[i]) != EOF) {
        fscanf(file, "%s", second[i]);
        i++;
    }

    for (j = 0 ; j < i ; j++ ) {
        printf("first@%d: %s - ", j, first[j] );
        printf("second@%d: %s\n", j, second[j] );
    }

    return 0;
}

输入:

these are
some words
to put
into a
matrix for
some fun

输出:

% ./a.out
first@0: these - second@0: are
first@1: some - second@1: words
first@2: to - second@2: put
first@3: into - second@3: a
first@4: matrix - second@4: for
first@5: some - second@5: fun
