As we talked about in the c with a spoon lecture, I tried the
pointer arithmetic and then free and at least for me it didn't
work.
gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)
[EMAIL PROTECTED]:~]$ gcc nis2.c
[EMAIL PROTECTED]:~]$ ./a.out
char y[0] a
char y[1] b
char y[2] c
char y[3] d
Segmentation fault (core dumped)

main(){
char *y = (char *)malloc(4*sizeof(char));
char *x = y + 2;
y[0]='a';
y[1]='b';
y[2]='c';
y[3]='d';
printf("char y[0] %c\n", y[0]);
printf("char y[1] %c\n", y[1]);
printf("char y[2] %c\n", y[2]);
printf("char y[3] %c\n", y[3]);
free(x);
printf("char y[0] %c\n", y[0]);
printf("char y[1] %c\n", y[1]);
// printf("char y[2] %c\n", y[2]);

exit(EXIT_SUCCESS);
