problem in structs

Code:

---

#include<stdio.h>

#include<string.h>

struct list

{

      char first[20];

      char name[20];

      char blahblah[40];

      };

    void get_struct(struct list * x);
      main()

      {

      struct list data[4];

      struct list *ptr;

      ptr=data;

      get_struct(ptr);

      }
    void  get_struct(struct list *x)

      {


      int i;


      for(i=0;i<4;i++)

      {
   

  ((x+i)->first)="storm"; 
     

      printf("\nfisrt=%s",(x+i)->first);

      printf("\nname=%s",(x+i)->name);

      printf("\nlif is =%s",(x+i)->blahblah);

      strcat((x+i)->first,(x+i)->name);

      printf("\nme =%s",(x+i)->first);



      }


      printf("Good Night");
   
  }

compiler give me this in line

Code:

---

((x+i)->first)="storm";

---

22 C:\Documents and Settings\St0rM\Desktop\test.c incompatible types in assignment
why so ?

can't do that, use strcpy()

also
1. int main should be used
2. fix indentation
3. pass array size together with array pointer - don't use "magic numbers" like 4 in the get_struct function
4. x[i].first is a lot easier to read than ((x+i)->first)

works prefect

Code:

---

#include<stdio.h>

#include<string.h>

struct list

{

      char first[20];


      char name[20];

      char blahblah[40];



      };



    void get_struct(struct list * x);

      main()

      {

      struct list data[4];

      struct list *ptr;

      ptr=data;

      get_struct(ptr);

      }

    void  get_struct(struct list *x)

      {

      int i;

      for(i=0;i<4;i++)

      {

   

      strcpy((x+i)->first,"storm"); 

      strcpy((x+i)->name," man"); 

      strcpy((x+i)->blahblah,"Is nothing But A good Lie"); 

      printf("\nfisrt=&#37;s",(x+i)->first);

      printf("\nname=%s",(x+i)->name);

      printf("\nlif is %s",(x+i)->blahblah);

      strcat((x+i)->first,(x+i)->name);

      printf("\nme =%s\n",(x+i)->first);

      }

      printf("Good Night");

      }

but why i can't do

Code:

---

((x+i)->first)="storm";

?
isn't x+i-> access the first array ?
thanks again

you can access the array with (x+i)-> operator (although I think x[i]. looks nices)

but you cannot assigh to array in C...

To put contents in the char-array - you should use string-manipulation functions like strcpy

1. int main should be used
2. fix indentation
3. pass array size together with array pointer - don't use "magic numbers" like 4 in the get_struct function
4. x[i].first is a lot easier to read than ((x+i)->first)
ahhaaaaaaa
thanks for this notices 4. x[i].first is a lot easier to read than ((x+i)->first)
specially this 4. x[i].first is a lot easier to read than ((x+i)->first)
but you cannot assigh to array in C...
so i can only access it's content's but i can't assign any thing for it except with string manipulations functions :)
thanks for the tips

When a char array is first declared, you can THEN add a string of char's:

char_array[] = "It's a pirate's life for me"

After the initial declaration of the char array, you can alter it char by char:

char_array[i] = 'P'

if you like.

You can use all kinds of equivalent pointer notation with arrays, but they quickly become a PITA to debug, etc. imo
