C infinite loop issue when prompting -


Why are an infinite loop without prompting re-users in the code 

 < Code> #include & lt; Stdio.h & gt; #include & lt; String.h & gt; # Include & lt; Ctype.h & gt; Zero to_rot13 (four * values); Int main () {four words [1024]; Printf ("C-rote 13 \ nSome code codes or decoded \ n"); While (1) {printf (":"); Scanf ("% [^ \ n] s", word); To_rot13 (& amp; शब्द); Printf (":% s \ n", word); } Return 0; } Zero to_rot13 (char * value) {unsigned int x; (X = 0; value [x]! = '\ 0'; x ++) {if ((value [x]  'A') (value [x] & gt; 'Z' & amp; ; Value (value [x] & gt; 'z')) {} and if (tolower (value [x]) <= 'm') {value [x] = value [x] + 13;} else {Value [x] = value [x] - 13;}}}   
 I would like to prompt the user again that I can not be more accurate.   
 
 
  scanf ("% [^ \ n] s", word);   
 Leaves the new line in the input buffer, so the next  scanf  does not immediately read any input, because the first  char  is a new line in the left buffer Land you must remove the new line from the input buffer.  
  int c; do {c = getchar ();} while (c! = '\ N' & amp; c! = EOF) ;; (C == EOF) {exit (EXIT_FAILURE); // Input Bourke}   
 In addition, keeping in mind the compiler's warning and the  word  To  to_rot13 .

Python SQLAlchemy：AttributeError: Neither 'Column' object nor 'Comparator' object has an attribute 'schema' -

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error. I am using Python 2.7.8 and the version of SQLAlchemy module is 0.9.8. By the way, using a project flask- SQLAlchemy, it works well, I'm confused.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
