error: invalid type argument of '->' (have 'struct node')
- by Roshan S.A
Why cant i access the pointer "Cells" like an array ? i have allocated the appropriate memory why wont it act like an array here? it works like an array for a pointer of basic data types.
#include<stdio.h>
#include<stdlib.h>
#include<ctype.h>
#define MAX 10
struct node
{
int e;
struct node *next;
};
typedef struct node *List;
typedef struct node *Position;
struct Hashtable
{
int Tablesize;
List Cells;
};
typedef struct Hashtable *HashT;
HashT Initialize(int SIZE,HashT H)
{
int i;
H=(HashT)malloc(sizeof(struct Hashtable));
if(H!=NULL)
{
H->Tablesize=SIZE;
printf("\n\t%d",H->Tablesize);
H->Cells=(List)malloc(sizeof(struct node)* H->Tablesize);
should it not act like an array from here on?
if(H->Cells!=NULL)
{
for(i=0;i<H->Tablesize;i++)
the following lines are the ones that throw the error
{ H->Cells[i]->next=NULL;
H->Cells[i]->e=i;
printf("\n %d",H->Cells[i]->e);
}
}
}
else printf("\nError!Out of Space");
}
int main()
{
HashT H;
H=Initialize(10,H);
return 0;
}
The error I get is as in the title-error: invalid type argument of '->' (have 'struct node').
