Write your own program when encountered this problem many times, most are pointers do not dynamically allocate space directly using subscript caused.
Like what:
Char *s;
cin>>s;
int Len=strlen (s);
for (int i=0;i
I've had this mistake a few times, and I'm going to be impressed. If it is a pointer and does not point to an array, use functions such as malloc to allocate space.
Char *s;
s= (char *) malloc (sizeof (char) *100);
cin>>s;
int Len=strlen (s);
for (int i=0;i
Or point the pointer direc
