C Programming - Pointers - Discussion

(*myPointer).element <=equals=> myPointer->element

Easily understandable good.

Thank u everyone for the explanation

Thanks buddies.

Kan you give some example @Kisan, you provided information is very understandable but it would be lot better, if you can post some examples to your thoughts.

I hope that given simple program clear your doubts.

#include<stdio.h>

struct node { //creating structure with a variable(val)
int val;
};

typedef struct node item;

void main() {
item *t; // declaring a struct type pointer variable

t=(item *)malloc(sizeof(item)); //allocating memory to struct
type pointer variable(t)
t->val=20; //accessing structure member(val) by using (t)
printf("value is %d",t->val);
}

Here item *t; is struct type pointer variable.So,By using struct type pointer variable(t),you can access the members of the structure(val) using the symbol ->

eg:- t->val=20;

Just copy and execute the program.

-> indicates direction toward's something and pointer is used for that in c.

Can any one help me by telling how execute programs on India bix (c) through online compiler by giving my own input at command prompt.

@sidesh:

In the above code instead of writing t->val=20;,

we can write
(*t).value=20; thats it..

. operator use when we have to acces stru member with array.

-> when we have to acces with pointer.
