    Dear Banfa

    Thanks for your reply. Your suggestion works well.

    I also found an alternate way to do it. In fact somewhere in the web, I read that when declaring a struct, one has to know the array size apriori. But this is not true. For instance, the following program works
    Code:
    //---------------------------------------------------------------------------------------
#include <stdio.h>
#include <stdlib.h>
    ...

      Multi-Dimensional variable in struct in C program

      I am stuck with how to access a 2-d array declared in a structure. For instance, I have declared a struct as follows:

      Code:
      struct sv {
float a[10][10];
};
      Now in main function, how to access the variable 'a'? I tried the following

      Code:
      main () {
struct sv * p;
p = (struct sv *) malloc (sizeof(struct sv));
*(p->*(a+1)+1) = 20.0;
printf("%f\n",*(p->*(a+1)+1));
      ...
