Thread: nested structs

Hi,
I have 3 structs that I am trying to work with.

Code:

typedef struct{
        char time[ARRAY_SIZE];
        char date[ARRAY_SIZE];
}ARRAY1, 2_ARRAY;
 
typedef struct{
      char name[10];
       ARRAY1 *main;
   }first;
 
typedef struct{
      char names[10];
       2_ARRAY *other;
    }second;

How do I assign values to the second struct ?
I am getting confused.

lotta luv

What do you mean by "assign values to the second struct"? If you had a variable of type first, then you would use .name and .main to access the char array and ARRAY1 array, respectively.

Side question: Do you intend for ARRAY1 and 2_ARRAY to mean the same thing?

oh ok...whats the syntax for assigning time through the "struct second"

I also would not use the variable name of "*main".

thank you,
Just one last question is the malloc needed here...?

I am trying to get this to work.

Code:

typedef struct{
        char time[ARRAY_SIZE];
        char date[ARRAY_SIZE];
}ARRAY1, 2_ARRAY;
 
typedef struct{
      char name[10];
       ARRAY1 *main;
   }first;
 
typedef struct{
      char names[10];
       2_ARRAY *other;
    }second;
 
       struct first *ptr;
       struct second *new;
        ptr = &first_info;
        new = &second_info;

strcpy(first_info.main[count].key,tokens[i]);

I am getting this error at

strcpy(first_info.main[count].key,tokens[i]);
line 115: syntax error before or at: *

Please help

CORRECTION..
this is the code having error

strcpy(first_info.main[count].time,tokens[i]);
line 115: syntax error before or at: *

Actually the line is in the main().
Its not in any function.

The code is too long.

Here is the code I am trying to run
