Rewrite the function shown below so that it is no longer vulnerable to a stack buffer overflow.
int main(int argc, char *argv[])
{
int valid = false;
char str1[8];
char str2[8];
next_tag(str1);
gets(str2);
if (strncmp(str1, str2, 8) == 0)
valid = true;
printf("buffer1: str1(%s), str2(%s), valid(%d)n", str1, str2, valid);
}
