Hi,
I have 3 structs that I am trying to work with.
How do I assign values to the second struct ?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;
I am getting confused.
lotta luv
2_ARRAY is not a valid name.
Perhaps something like this?
--Code:first x;
x.main = ... (something like malloc, perhaps)
strcpy(x.main->time, "12:01:59");

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"
Aside from the code not compiling as the name (2_ARRAY) starts with a digit, it would be similar to the first case.Quote:

I do agree - don't call other things than the main entry function "main".Quote:

But that is distinct from "main" because it's inside the struct itself - it can not be used on it's own - it will always be preceded by a variable name and . or ->

Just add more dots.
foo.outerMember.innerMember = 1;
foo.outerPtr->innerMember = 2;
etc etc
thank you,
Just one last question is the malloc needed here...?
If you've got pointers, then you need to make them point somewhere.
One popular way is to use malloc.
I am trying to get this to work.
I am getting this error atCode: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]);
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: *
> strcpy(first_info.main[count].key,tokens[i]);
So is this line of code actually inside a function?
Also, having a member called main is going to be confusing, since there's also a function with the same name.
A complete example which we can copy/paste into a compiler is much better than simply snipping the lines which you think are relevant.
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
Code:
#include<stdio.h>
#include<stdlib.h>
#include<string.h>
#include<regex.h>
#define ARRAY_SIZE 340
#define STRUCT_SIZE 340
#define MAXTOKENS 256
#define MAXLINE 1024 /* fgets buff */
#define MINLEN 3 /* skip lines shorter as */
#define NUL '\0'
#define TRUE 1
#define FALSE 0
