c - How can I access members in an array of structures that I passed into a function by value? -

#include <stdio.h> #include "inventorymanager.h"  void displayinventory(const struct item items[], const int size) { printf("\n\n"); printf("inventory\n"); printf("=========================================\n"); printf("sku         price       quanity\n"); int index = 0; (index = 0; index < size; index++) {     printf("%-10.0d  %-10.2f  %-10d\n", items[index].sku, items[index].price, items[index].quantity); } printf("=========================================\n"); } 

i getting red underlining under "items" when try access structure values within array.

i have 3 files, inventorymanger.h, inventorymanager.c, shopping_lab_2.c ... struct called item created in shopping_lab_2.c, , function seeing on stack overflow made in inventorymanager.c.

i not sure how call function. program below works without errors or warnings:

struct item{  int sku;  float price;  int quantity;  };    void displayinventory(const struct item items[], const int size) { printf("\n\n"); printf("inventory\n"); printf("=========================================\n"); printf("sku         price       quanity\n"); int index = 0; (index = 0; index < size; index++) {    printf("%-10.0d  %-10.2f  %-10d\n", items[index].sku, items[index].price,    items[index].quantity); } printf("=========================================\n"); }  int main() {  item items[2] = {1, 1.1, 10, 2, 2.2, 20 }; // initialization  displayinventory(items, 2);  return 0; } 

output:

inventory ========================================= sku         price       quanity 1           1.10        10         2           2.20        20         =========================================
