string - Parse a file in c++ and ignore some characters -


i'm trying parse file has following information

test_wall ; comments!! je,5 forward goto,1 test_random; je,9

i'm supposed ignore comments after ";" , move on next line. when there comma i'm trying ignore comma , store second value.

string c; int a;  c=getchar();  ifstream myfile (filename); if (myfile.is_open()) {    while ( c != ';' && c != eof)    {        c = getchar();        if( c == ',')        {          a= getchar();        }     } } myfile.close(); }

here's code. i'm not entirely sure i've understood problem correctly, if not set on right direction.

ifstream myfile (filename); if (myfile.is_open()) {    // read 1 line @ time until eof    string line;    while (getline(myfile, line))    {        // line have semi-colon?        size_t pos = line.find(';');        if (pos != string::npos)        {            // remove semi-colon , afterwards            line = line.substr(0, pos);        }        // line have comma?        pos = line.find(',');        if (pos != string::npos)        {            // after comma            line = line.substr(pos + 1);            // store string            ...        }    } }

i've left section commented 'store string' blank because i'm not want here. possibly asking convert string integer before storing it. if add code, or ask if don't know how that. don't ask, search on stack overflow, because question has been asked hundreds of times.

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
