C從TexFile創建數組

Question

我正在嘗試從文本文件創建一個單詞數組。我能夠得到它打印出正確的值，但我需要一個實際上可以使用的數組。有了這個數組之後，我必須對所存儲的單詞進行各種操作，例如統計每個單詞的長度。現在我只需要幫助製作一個我可以實際使用的數組。

下面是代碼：

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


int main (int argc, char* argv[]){ 
    // First Read in First novel File 
    FILE *fp; 
    char *ProgFile; 

    // Variables for Parsing 
    int i = 0; 
    int j=0; 
    char *cp; 
    char *bp; 
    char line[255]; 
    char *array[5000]; 
    int x; 
    int wordCount=0; 
    int wordCountPerNovel; 


    // Adjusting the file name to include txt and corresponding number 
    strcat(argv[1],"_1.txt"); 
    ProgFile = argv[1]; 

    // Open Each File 
    fp=fopen(ProgFile,"r"); 
    if(fp==NULL)printf("error"); 
    else printf("bin file loaded: '%s'",ProgFile); 
    // Now begin analysing 
    // Part 1 
    // Parse Entire Document into Array of Strings 
    while (fgets(line, sizeof(line), fp) != NULL) { 
      bp = line; 
      while (1) { 
        cp = strtok(bp, ",.!?<97> \n"); 
        bp = NULL; 
        if (cp == NULL)break; 
        array[i++] = cp; 
        printf("Check print - word %i:%s:\n",i-1, cp); 
      } 
    } 
    // At this point i is the last word that was iterated, -1 since it breaks out after being added 
    // This gets total words of all novels 

    wordCount=wordCount+(i-1); 
    printf("\nTotal words %i\n",wordCount); 
    // Find Total number of letters 
    //for (i=1;i<15;i++){ 
    //  printf("My value: %s \n",finalArrayWord[i]); 
    // 
    //}

的代碼沒有編譯。如果你知道長度，你可以使用char數組，並且你不必使用malloc從文件讀入數組。

文件1.txt的

Sed ut perspiciatis unde omnis iste natus error sit voluptatem accusantium doloremque laudantium, totam rem aperiam, eaque ipsa quae ab illo inventore veritatis et quasi architecto beatae vitae dicta sunt explicabo. Nemo enim ipsam voluptatem quia voluptas sit aspernatur aut odit aut fugit, sed quia consequuntur magni dolores eos qui ratione voluptatem sequi nesciunt.

代碼

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

void read_words (FILE *f) { 
    char x[1024]; 
    char **a; 
    a = malloc(1024 * sizeof(char*)); 
    for (int i = 0; i < 1024; i++) 
     a[i] = malloc((1024+1) * sizeof(char)); 
    int i = 0; 
    while (fscanf(f, " %1023s", x) == 1) { 
     strcpy(a[i], x); 
     i++; 
    } 
    for (int j = 0; j < i; j++) { 
     printf("%d %s\n", j, a[j]); 
    } 
} 
int main(void){ 
    read_words(fopen("1.txt", "r")); 
    return 0; 
}
