index returns a pointer to the first occurrence of a character in a
string. The first occurrence of the first character in the string will
be the same as a pointer to the string, but with more work.
sprintf(string1, "%c", original[0]);
if (original[0]) // make sure it wasn't an empty string
strcpy(string2, &original[1]); // copy original+1 char to string2
