c - 在C中将单词存储在单词的结构数组中

当我尝试递增以在单词的结构数组中存储另一个单词时，我有一个程序崩溃的问题。该程序可以正确读取每一行和每个单词，但是由于某些原因，当我尝试增加以存储更多单词时，它总是崩溃。有什么建议么？

textFile（输入）：

OK UH UH SOUND FIELD IS UP
OK RUNNING TEST SERIES
OK
SOUTHWEST SOUTHWEST CONFIRMED
PEEN HIT CONFIRMED ARMED FIRE
AND THAT'S TWO UM WHAT YOU WANT TO MOVE A LITTLE CLOSER
OK
OK
PEEN FORE CONFIRMED ARMED
ARMED FIRE
THAT'S A THREE ARMED FIRE
OH THAT'S ONLY A TWO OK
GOING TO LASER CANNON
BOX THAN OK I'M GOING TO GO FOR BAD CHOP CAN YOU CONFIRM BAD CHOP
FIRE
UH HOLD ON ARMED FIRE
OK
GO NEED ARMED FIRE
THAT WAS A REPEAT HE'S MOVING OUT
YEP YOU WANT TO GO AHEAD OF HIM
OK
YOU WANT TO DO A SWEEP
SUE BID ARMED
FIRE
OK
DEED NEED I'M GOING TO OK I'M GOING TO GO FOR SUE ZOO ARMED
FIRE
OK I'M GOING TO GO FOR DEED YEN
DEED YEN DEED YEN
FIRE
OK I NEED A SWEEP

结构代码：

typedef struct {
  char word[maxLetters];
  int  freq;
} WordArray; //struct type

主要代码：

#define maxLetters 101
#define maxWords 200
int inputReader(WordArray input[], char f[maxWords]){

// ATTRIBUTES //
int i = 0;
int uniqueWords = 0;
int contains = 0;
int numOfWords = 0;
int k = 0;

FILE *finput;
char lineOfWords[1000];

finput = fopen( f, "r");



WordArray allWords[maxWords];


while(fgets(lineOfWords, maxWords, finput) != NULL) { // reads each line of words

     // PROBLEM IS HERE
     while(fscanf(finput, "%s", allWords[numOfWords].word) == 1) // reads each word from line
     {

        printf("%s\n", allWords[numOfWords].word);// this works
        //numOfWords++;    if i add this i receive the error
                          // "Segmentation Error(core dumped)"


     }
}

return 0; // default ignore this
}

最佳答案

您的程序崩溃是因为您没有限制读取的单词数，应该添加到外循环中，

(numOfWords < maxWords)

以及我在源代码中添加了注释的其他一些问题，我还修复了使用strtok作为解析部分从文件中读取的内容。

int inputReader(WordArray input[], char f[maxWords])
{
    (void) input;
    // ATTRIBUTES //
    int numOfWords = 0;

    FILE *finput;
    char lineOfWords[1000];

    finput = fopen( f, "r");

    WordArray allWords[maxWords];

    /*
     * tell fgets NOT to read more than sizeof(lineOfWords) bytes,
     * not maxWords, they are unrelated
     */
    while ((fgets(lineOfWords, sizeof(lineOfWords), finput) != NULL) && (numOfWords < maxWords)) { // reads each line of words
        char *pointer;
        char *token;

        pointer = lineOfWords;
        /* also prevent overflowing the struct array */
        while (((token = strtok(pointer, " ")) != NULL) && (numOfWords < maxWords)) {
           /* next call to strtok for the same string requires first parameter to be NULL */
            pointer = NULL;
            /* strncpy prevent copying more than maxLetters bytes */
            strncpy(allWords[numOfWords].word, token, maxLetters - 1);
            /* ensure null terminating byte */
            allWords[numOfWords].word[maxLetters - 1] = '\0';

            numOfWords++;
        }
    }
    /* don't forget to close the file */
    fclose(finput);
    return 0; // default ignore this
}
