c++ - How can I mark the end of a C string? -

-

here code function:

void pattern(char word[200], char aspattern[200]) {     (unsigned = 0; < strlen(word); i++) { // unsigned remove warning         if (strchr("aeiou", word[i]) != 0) aspattern[i] = '*';         else aspattern[i] = '#'; }

basically function replaces consonants in word #'s , vowels *'s, , stores new pattern in aspattern string. however, if display aspattern on screen, shows correct pattern followed bunch of unknown symbols (strlen(aspattern) equals 211 or after loop). believe problem aspattern's end isn't marked , aspattern[strlen(aspattern)] = '/0' doesn't work , don't know else do...

i cannot use std::string, please bear me , use c strings.

add code

aspattern[strlen(word)] = '\0';

either before or after for-loop

apache - Error with PHP mail(): Multiple or malformed newlines found in additional_header -

-
suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
