let's have a look...

This isn't valid, you can't 'strncpy' single characters to a string.
It SHOULD give you a warning on that.

>>         strcat(line,null);

No, it was probably already wrong on the previous line. 

>> void main(int argc,char *argv[])

why is this a problem ?

It's 100% legal to declare main as any of the following

void main (void)
int main (void)
void main (int argc, char *argv[])
int main (int argc, char *argv[])
void main (int argc, char **argv)
int main (int argc, char **argv)
void main (int argc, char *argv[], char *envp[])
int main (int argc, char *argv[], char *envp[])
void main (int argc, char *argv[], char **envp)
int main (int argc, char *argv[], char **envp)
void main (int argc, char **argv, char *envp[])
int main (int argc, char **argv, char *envp[])
void main (int argc, char **argv, char **envp)
int main (int argc, char **argv, char **envp)

erhm..  that should be it, I may have missed one...
