[LCP]Very Small Doubt...

["Goverthanan" <verthan@miel.mot.com>]

hi all,

this is a very small doubt in c.

On execution the following program throws segmentation fault error.

#include <stdio.h>
#include <string.h>

 

main()
{
int n;
char *str, *str1;
scanf("%s", str);
scanf("%s", str1);
scanf("%d",&n);
printf("%d\n", bcmp(str, str1, n));
}

 

Instead when the order of variable declaration is changed, program worked fine.

 

May i know what makes the diffenence in the order of variable declarations.

 

Regards,

Goverthan
