c++ - What does "void-value is not ignored" error mean and how to remove it? -


i try compile following code:

#include <cppunit/extensions/helpermacros.h> #include "tested.h"  class testtested : public cppunit::testfixture {         cppunit_test_suite(testtested);         cppunit_test(check_value);         cppunit_test_suite_end();          public:                 void check_value(); };  cppunit_test_suite_registration(testtested);  void testtested::check_value() {         tested t(3);         int expected_val = t.getvalue(); // <----- line 18.         cppunit_assert_equal(7, expected_val); }

as result get:

testing.cpp:18:32: error: void-value not ignored should

eddit

to make example complete post code of tested.h , tested.cpp:

tested.h

#include <iostream> using namespace std;  class tested {     private:         int x;     public:         tested(int int_x);         void getvalue(); };

tested.cpp

#include <iostream> using namespace std;  tested::tested(int x_inp) {     x = x_inp; }  int tested::getvalue() {     return x; }

you declare void getvalue(); in class tested.. change int getvalue();.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
