problem with nested structures

[samba]

I having a nested structures which are referenced with pointer variables

#include <stdio.h>
struct test
{
  int i;
  char *mytest;
};
struct sample
{
  int k;
  struct test *test1;
};
int main()
{
  struct sample *mysample;
  printf("Inside main method \n\n");
  mysample->k=0;
  mysample->test1->i=1;  // It's throws segmentation fault error at this point how to access this variable.
  printf("the value of the k is  %d \n\n",mysample->k);
  //  printf("the value of the k is  %d \n\n",mysample->test->i);
  return 0;
}

please help me as soon as possible

Moved to C++ forum.

you need to point the pointer sat some objects, e.g.

 struct sample s;
  struct sample *mysample=&s;
  printf("Inside main method \n\n");
  mysample->k=0;
  struct test t;
  mysample->test1=&t;  
  mysample->test1->i=1;  // It's throws segmentation fault error at this point how to access this variable.
