all of fellas, have problem code. try use macro , vector in code. but, there error in code, in macro code. dont know error. code : #include <iostream> #include <vector> #include <string> #include <algorithm> #include <ostream> using namespace std; #define loop(a,b) for((int)(a) = 0; (a) < (int)(b); (a)++) int main(){ vector<string> sentence; sentence.reserve(10); int i=0, c = sentence.size(); sentence.push_back("hello,"); sentence.push_back("how"); sentence.push_back("are"); sentence.push_back("you"); sentence.push_back("?"); loop(i,c){ cout << << endl; } return 0; } i hope of can me solve problem. regards. it bad idea use such kind of macros in c++. problem expression ( int )( ) is rvalue (some temporary object) , may not assign value like ( int )( ) = 0; either remove entirely casting or @ least use c

i'm trying implement filtering on input element. want make filtering input type="text" field. instance, if model contain more available characters want change input value. i've created jsfiddle have directive generate html template dynamically , contains input field. var app = angular.module('app', []) .controller('ctrlr', function($scope){ $scope.mymodel = "test"; $scope.availablecharacters = 5; $scope.$watch('mymodel', function(newvalue, oldvalue){ if(!newvalue){ return; } if(newvalue.length > 5){ $scope.cutstring(); } }); $scope.cutstring = function(){ var length = $scope.mymodel.length; var string = $scope.mymodel.slice(0, $scope.availablecharacters); var countstars = length - string.length; $scope.mymodel = $scope.createstars(string, countstars); } $scope.createstars = function(string, count

i have found interesting happen maps, rawtypes , generics. following code: static { map map = new hashmap (); set <map.entry> set = map.entryset (); (map.entry entry : set) {} // fine (map.entry entry : map.entryset()) {} // compilation error } i getting compilation error type incompatibility, namely: "object cannot cast entry". ideone convenience why iterator on entryset() losing type information if there's no variable storing again? the rawtypes shouldn't affect type map.entry object. or mistaken? your example makes have type information never had. have written: map map = new hashmap (); set <map.entry> set = map.entryset(); (map.entry entry : set) {} // fine (map.entry entry : map.entryset()) {} // compilation error but map.entryset() returning set , not set <map.entry> . you've performed unchecked assignment "adds" type information. in second loop, don't

swap<t, position1, position2, pack>::type , pack consists of elements of type t, return pack elements in position1 , position2 swapped. solution below not efficient. there should way accomplish cleanly, without visiting element twice . can think of it? // replaceelement replaces element of pack specified position (0 being first position) specified value. template <typename t, std::size_t, std::size_t, t, typename, typename> struct replaceelementhelper; template <typename t, std::size_t position, std::size_t currentposition, t newvalue, template <t...> class z, t first, t... rest, t... accumulated> struct replaceelementhelper<t, position, currentposition, newvalue, z<first, rest...>, z<accumulated...>> : replaceelementhelper<t, position, currentposition + 1, newvalue, z<rest...>, z<accumulated..., first>> {}; template <typename t, std::size_t position, t newvalue, template <t...> class z, t first, t... r

program description i used .blkw allocate 20 locations each character user inputs , now, want display string user typed @ first prompt. (this pig latin translator, hence second prompt; right want see if can print out user input) the problem the problem when run it, characters @ end. for example: english word: apple pig-latin word: apple english word: @ pig-latin word: atple english word: set pig-latin word: setle my program .orig x3000 start st r1,saver1 st r2,saver2 st r3,saver3 ld r5,enter repeat lea r0,prompt ; loading starting address of prompt puts ; displays prompt on screen lea r4,englword ; sets aside memory locations typed characters input getc ; user has typed, read char r0 add r6,r5,r0 ; adds negative value of ascii enter key code input character brz pigprompt ; if sum of ascii codes step before 0, means user pressed enter go pigprompt out ; write char in r0 console str
