fread() function 打印一行额外的随机字符

Question

I am trying to read data from a file and save it to a struct and print it to a screen. Everything works but it print and extra line of characters. I tried using malloc but I don't think I am using it correctly. Here is the code.

void SearchItem(struct grocery NewList) {
    struct grocery NList;
    char sitem[50];
    
    NList.list = fopen("grocerylist.txt", "r");

    if (NList.list == NULL) {
        printf("File could not be opened. \n");
    } else {
        fseek(NList.list, 0, SEEK_END);
        int sz = ftell(NList.list);
        rewind(NList.list);
        char *Data = (char *)malloc(sz + 1);
  
        for (int i = 0; i < strlen(Data); i++) {
            fread(&NList, sizeof(struct grocery), 1, NList.list);
         
            if (NList.item_name != NULL) {
                printf("\n %s %.2f %d", NList.item_name,
                       NList.unit_price, NList.quantity);
            } else {
                 printf("Item unavailable.\n");
            }
        }
    }
    fclose(NList.list);
}

Here is the output from file

and here is the contents of the file

How do I Fix This

Answer 1

Thanks to all your comments they led me to a solution.

Here is what fixed my code,

while(.feof(NList.list))

I Changed the for loop back to a while loop and

fscanf(NList.list, "%[^ ] %f %d\n", NList.item_name, &NList.unit_price, &NList.quantity);

Instead of fread() I used the fscanf() and instead if using %s for the string, I used %[^ ] and the \n allowed it to read the next line.
