c++ - Where to put main and what to write there? -


i have following code in file tested.cpp:

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

i have file (called testing.cpp):

#include <cppunit/extensions/helpermacros.h> #include "tested.cpp"  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();     cppunit_assert_equal(7, expected_val); }

when try compile testing.cpp file get: undefined reference tomain'`. well, because not have main (the entry point program). so, compiler not know how start execution of code.

but not clear me how execute code in testing.cpp. tried add:

int main() {         testtested t();         return 1; }

however, not print (and expected return error message since 3 not equal 7).

does know correct way run unit test?

since writing cppunit test, why not looking @ cppunit doc ? (http://cppunit.sourceforge.net/doc/lastest/cppunit_cookbook.html)

it tells main sould written :

#include <cppunit/ui/text/testrunner.h> #include "exampletestcase.h" #include "complexnumbertest.h"  int main( int argc, char **argv) {   cppunit::textui::testrunner runner;   runner.addtest( exampletestcase::suite() );   runner.addtest( complexnumbertest::suite() );   runner.run();   return 0; }

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
