objective c - How to insert string that contains " character in sqlite ios -


I am using the following code but sqlite is giving me an error 

  NSArray * a = [Object with NSArray array: @ "\" "@" \\ \ "", zero]; Volume = [volume stringing implication ocurrenceoffstring: [an objectwithoutx: 0] with string: [an object atindex: 1]]; queryString = [NSString stringWithFormat: @ "Include Shopping List (Quantity) values ​​(\"% @ \ ")", quantity];   
 This error returns to: - "diax1": the syntax error in the query is the original amount = 1 piece in the shopping list, medium (4-1 / 2 "diax1 / 8" thick ) Use placeholders to insert special characters in the SQLite (also see which special characters are allowed in Sqlite):  
  queryString = @ "shoppinglists (quantity) included in the values Do (?) "; Sqlite3_stmt * Compiled Statement; If (sqlite3_prepare_v2 (database, query string, -1, and compiled location, zero) == SQLITE_OK} {sqlite3_bind_text (compiled stability, 1, [quantity UTF8String], -1, SQLITE_TRANSIENT); // Use string values ​​for sqlite3_bind_text For other types of values, see the SQLite document. // .... and so on. }

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
