Function that takes in array of characters as parameter

I'm writing a function that is supposed to add a Product object to an array of Products and also initialize the data members for each Product object. I'm running into an issue where I can't figure out how to initialize my name and category data members, both of which are an array of characters and would appreciate some help. I tried changing the parameters to things like 'char[] name' or 'char name[]' but it's not working out.


I'm trying to compile my program below but I keep getting the errors:

Code:

---


    store.c: In function ‘addProduct’:
    store.c:24:40: error: assignment to expression with array type
      productArr->products[productArr->numProducts]->name = name;
                                            ^
    store.c:25:33: error: ‘ProductType {aka struct <anonymous>}’ has no member named ‘category’
      productArr->products[productArr->numProducts]->category = category;

---

store.c

Code:

---

    int addProduct(ProductArrType* productArr, char name, char category){   
        productArr->products[productArr->numProducts] = malloc(sizeof(ProductType));
        productArr->products[productArr->numProducts]->name = name;
        productArr->products[productArr->numProducts]->category = category;
        return 1;
    }

---

defs.h

Code:

---

    #define MAX_RUNNERS  10
    #define MAX_STR  30


    typedef struct {
      char category[MAX_STR];
    } EntityType;


    typedef struct {
      char name[MAX_STR];
    } ProductType;


    typedef struct {
      int numProducts;
      ProductType *products[MAX_PRODUCTS];
    } ProductArrType;

I'm guessing it is because "category" is in 'EntityType', and not in 'ProductType'.

In C, string are passed around as char *'s. They are arrays of char
terminated with a NUL. Since you have a buffer, you need to
call the function strcpy() to copy your input strings to this buffer.

So the prototype for the fucntion should be

Code:

---

int addProduct(ProductArrType *productArr, const char *name, const char *category):

---

The const isn't strictly necessary but makes it clear that you are not
modifying the input string, you are taking a copy of them.
