strcpy_s unhandled exception? - c++

Question

I'm trying to use strcpy_s, but I'm having this error:
Unhandled Exception...
struct Item {
//Item's
int code; // Code
char* name[20];
int amount; //Amount in stock
int minAmount; //Minimum amount
float price; //Price
};
The important lines are the beginning and the line with the "#########" beside it. (spot = 0, name string was received, store was initialized in main()).
//add an item to store
void addItem(Item* store, int maxItems, int &numItems)
{
if (maxItems == numItems)
{
cout << "ERROR \n";
return;
}
int spot = numItems; // our item's spot in store[]
int code; // inputted code
//Item's attributes' input
cout << "enter code : \n"; //code
cin >> code;
store[spot].code = code; //Code
cout << "enter name : \n"; //Name
_flushall();
char* name = new char[20];
gets_s(name, 20);
numItems++; //forward the number of items
strcpy_s(*store[spot].name, 20, name); //Name UNHANDLED EXCEPTION ############################
cout << "enter amount : \n"; //Amount in stock
do
{
cin >> store[spot].amount;
if (store[spot].amount < 0) //not negative
cout << "ERROR \n";
} while (store[spot].amount < 0);
cout << "enter minimum amount : \n"; //Minimum amount for orders
do
{
cin >> store[spot].minAmount;
if (store[spot].minAmount < 0) //not negative
cout << "ERROR \n";
} while (store[spot].minAmount < 0);
cout << "enter price : \n"; //Price
do
{
cin >> store[spot].price;
if (store[spot].price < 0) //not negative
cout << "ERROR \n";
} while (store[spot].price < 0);
}

Answer 1

I would advice you to test calling strcpy_s and every other suspicious part of the code separately and see it there is any problem, if there is, work around it and then insert it in the addItem function.
From is visible in the posted code, you seem to be passing a pointer variable with the dereference operator in front of it in most of the functions you use, for example the signature of strncpy_s() is:
errno_t strncpy_s(char *restrict dest,
rsize_t destsz,
const char *restrict src,
rsize_t count);
You need to pass the first parameter without the * as it is a pointer: Item* store, i.e. as pass it as: store[spot].name.
Check this article about pointer assignment, which will help you understand how to pass a pointer as an argument to a function.
Edit after a comment
Your second error message could be because the member name of store is not a pointer, you probably need to pass it using & operator, i.e. pass its address:
strcpy_s(&store[spot].name, 20, name);
