Question

我正在尝试从文本文件中创建一个单词数组。我可以让它正确打印出值，但我需要一个我可以实际使用的数组。在我拥有这个数组后，我必须对我存储的单词做各种各样的事情，比如计算每个长度。现在我只需要帮助制作一个我可以实际使用的数组。

以下是代码：

# 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]);
    //
    //}

代码没有编译。如果您知道长度可以使用char数组，则不必使用malloc从文件读取数组。

文件 1.txt

代码

#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;
}
