Я стремлюсь создать связанный список для пищевых ингредиентов из массива символов, хранящегося в файле C (rawRecipies.h). Однако после запуска кода в терминале ничего не появляется. Ранее я столкнулся с ошибкой сегментации. После настройки кода я не получаю вывод.
Я проверял свой код несколько раз и предоставил достаточно места для хранения ингредиентов в моем LinkedList. Тем не менее, я не могу найти источник этой проблемы.
Вы можете заметить, что я добавил несколько точек выхода в коде. Я сделал это для отладки, но они не помогают.
Пожалуйста, дайте мне знать, что не так. Заранее спасибо.
Код ниже:
#include <stdio.h>
#include <stdlib.h>
#include "rawRecipes.h"
#include <string.h>
#include <stdbool.h>
//ASSUMING THESE LIMITS
#define MAXRECIPES 30 /* max # of recipes */
#define MAXINGREDIENTTYPES 250 /* max # of ingredient types */
#define MAXINGREDIENTS 250 /* max # of ingredients all recipes */
#define MAXCHARS 100 /* max characters for recipe or ingredient*/
#define INGMAX 25 /* max ingredient count per recipe*/
// structure declarations
struct Ingredient {
char IngName[MAXCHARS];

// struct for storing items from rawRecipies.h

if (newNode != NULL) {

// Code to find Ingredients and store them in ingredientList.
for(index = 0; (strcmp(items->recipe[index],"") != 0);) {
if(strncmp(items->recipe[index], "1", 1) == 0) {
strcpy(ingredientList[index], (items->recipe[index])+1);
index++;
}
}
// creating a duplicated Ingredient LinkedList:
int i;
for (i = 0; i < index; i++) {
// evaluating and checking the function to add LinkedList for Ingredient
insertIngredientAtBack(list2, ingredientList[i]);
}
}
void ListAllIngredients(linkedListIngredient* list2) {
Ingredients* current = list2->head;
int counter = 1;
while(current->next != NULL) {
printf("Ingredient #%d: %s\n", counter, current->IngName);
counter++;
current = current->next;
}
printf("Recipe #%d: %s\n", counter, current->IngName);
}
int main(void) {
// instantiating the structures for linkedlist access
linkedListIngredient list2;
// holds database for ingredients and recipes
records items;
// copying all values from rawRecipies.h
int i;
for(i = 0; (strcmp(rawRecipes[i], "") != 0); i++) {
strcpy(items.recipe[i], rawRecipes[i]);
}
// first move data from rawRecipes.h to a data structure
convertInputToDataStructure(&list2, &items);
ListAllIngredients(&list2);
}
Как уже упоминалось, rawRecipe.h содержит массив указателей символов. Из этого массива я просто заинтересован в сборе строк с 1 перед ним для моего связанного списка ингредиентов. Это все ингредиенты.
