variables - Prolog, working with capital letter -


I am working on a database project in SWI-Prolog. The problem is that I work with the names of those players I wanted to read from the input. I need to save my names with capital letters, but interpret them as Chola. Any ideas how to fix this?

I use code_type / 2 to ensure that no one The name starts with the capital letter.

Since you want to allow a user to enter a name with a letter that is lower or uppercase, I do a case conversion on the code list. I read_line_to_codes / 2 I read with

Since you want to store names in a database, I use dynamic / 1 to declare that I have some game name / entries, and I use the dependent / 1 to add a specific name to the database.

Here's the code: 

 : - Dynamic (play name / 1). - initialization (input) input: - Repeat, format (user_output, 'Please enter a name (or type drop' '): \ n', []), read_line_to_codes (user_input, code1), (atom_codes (left , Code 1) - & gt;!, True (code1, code2) -> atom_codes (name, code2), emphasize (play name (name)), format (current_output, 'playname' Author. \ N ', [name]), failed;). Capital make ([], []) to make capital ([H1 | T], [H2 | T]): - examples of code_type (H2, to_upper (H1))   
 Usage:  
  $ swipl sports_names.pl Please enter a name (or type 'leave'): | . Please enter a name (or type 'leave'): | James Sportsman James wrote to the database. Please enter a name (or type 'leave'): | Susan Sportsman Suzan wrote to the database. Please enter a name (or type 'leave'): |: left? - Game name (X) X = 'John'; X = 'James'; X = 'Susan'   
 Hope it helps!

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. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

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...
