Thread: instances of a structure in a structure

Hi,

I have the following structure, made up of four structures:-

Code:

struct customer_details {
    struct1;
    struct2;
    struct3;
    struct bundle_info bundle_data;
}thisCustomer;

the structure bundle_info is made up as follows....

Code:

struct bundle_info {
    char x;
    char y;
}

This has four instances...

Code:

struct bundle_info bundle1;
etc.

Now my question is thus...how do I assign values to one of these instances?

I thought it would be...

memcpy(thisCustomer.bundle1.x, buf, 5)

where buf is a character array.

However, this gives the error "bundle1 is not a member of thisCustomer".

Any ideas?

Bill

I'm not sure what you want, but here an example:

Code:

#include <stdio.h>
#include <stdlib.h>

struct bundle_info 
{
   char x;
   char *y;
   char z[100];
};

struct customer_details 
{
   int nr;
   struct bundle_info bundle_data[10]; /* 10 instances */
};

int main(void)
{
   customer_details thisCustomer;

   thisCustomer.nr = 1;
   thisCustomer.bundle_data[0].x = 'a';
   thisCustomer.bundle_data[9].x = 'j';
   /* y is a character pointer so we need to allocate space before copying */
   thisCustomer.bundle_data[0].y = strdup("Hello Y");
   strcpy(thisCustomer.bundle_data[0].z, "Hello Z");

   printf("%s\n", thisCustomer.bundle_data[0].y);
   printf("%s\n", thisCustomer.bundle_data[0].z);
   free(thisCustomer.bundle_data[0].y);
   return 0;
}

Hope it helps...

Cheers,
