Question

Trying to get my head around the old C language. Currently on structs and getting this error:

"variable 'item1' has initializer but incomplete type"

Here’s my code:

typedef struct
{
    int id;
    char name[20];
    float rate;
    int quantity;
} item;

void structsTest(void);

int main()
{
    structsTest();

    system("PAUSE");
    return 0;
}

void structsTest(void)
{
    struct item item1 = { 1, "Item 1", 345.99, 3 };
    struct item item2 = { 2, "Item 2", 35.99, 12 };
    struct item item3 = { 3, "Item 3", 5.99, 7 };

    float total = (item1.quantity * item1.rate) + (item2.quantity * item2.rate) + (item3.quantity * item3.rate);
    printf("%f", total);
}

I guessed perhaps the struct defintion was in the wrong location so I moved it to the top of the file and recompiled, but I am still getting the same error. Where’s my mistake?

Get rid of struct before item, you’ve typedef’d it.
