我一直遇到分段错误，但我找不到它！我想我已经把它缩小到一个特定的功能

Question

我说肯定是这个函数，因为我输入一个int它就停止了，它不读取打印语句

recipe** readAllRecipes(int numRecipes)
 {
   recipe** theRecipes = malloc(sizeof(recipe *) * numRecipes);
   int i;

   for(i = 0; i < numRecipes; i++)
   {
    scanf("%d", &theRecipes[i]->numItems);
    
    printf("\n\n\t\t here in readAll for loop\n");
    
    theRecipes[i] = readRecipe(theRecipes[i]->numItems);
   }

   return theRecipes;
}

Answer 1

这是问题所在：

        scanf("%d", &theRecipes[i]->numItems);

theRecipise[i] 未初始化，您取消引用它。应该先分配它：

        theRecipes[i] = malloc(sizeof(recipe));
        scanf("%d", &theRecipes[i]->numItems);

但低下我对此感到困惑：

    theRecipes[i] = readRecipe(theRecipes[i]->numItems);
