problem with const in structure

[Mohammed Khalid Ansari <khalid@ncst.ernet.in>]

Hi,

consider the following code.

####
#include <stdio.h>

struct node {
	const int x;
	char name[20];
	struct node *next;
};

int main()
{
	struct node newnode;
		
	newnode.x = 10;
	newnode.x = 12;
	printf ("x = %d\n", newnode.x);
	return 0;
}
####

Now, you can see that even though I have defined x to be const int, I can 
assign it values. When I compiled the program, it gives the warning that 
assignment of read-only member x but when I ran the program, it worked 
fine. Where is the catch. How do I define a structure variable to be 
const?

with regards...
