All #include <string.h> char *strchr(char *S, int c) returns a pointer to the first occurrence of c in S, or Null if c is not found. If S is "123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ1" and c is T then given Aptr = strchr(S, c); then printf( "%c\n", *Aptr); will yield T and printf( "%c\n", *Aptr+1); will yield U, but printf( "%c\n", *Aptr+7); does not yield 1, but rather [ where the ASCII values are (begin snip) | 80 P | 81 Q | 82 R | 83 S | 84 T | 85 U | 86 V | 87 W | 88 X | 89 Y | 90 Z | 91 [ | 92 \ | 93 ] | 94 ^ | 95 _ (end snip) so the pointer doesn't seem to be to a position in S, but rather to an ASCII value.
Does that seem right, or am I missing something? Thank you in advance for any help you may be able to offer. Regards Fred James _______________________________________________ EUGLUG mailing list [email protected] http://www.euglug.org/mailman/listinfo/euglug
