Input multiple strings via operator>> c++


Input multiple strings via operator>> c++

this will help One call to operator>> of std::cin reads only up to the first whitespace. When you input 4 words in one line, your std::cin reads the first word, accepts it, and execution continues. But the remaining 3 words are still waiting in the input stream to be read, and they will be read upon next call of operator >>.
So, to illustrate what happens, here's an example:
code :
Input stream content: [nothing]
//(type usa americ england gana)
Input stream content: usa americ england gana
//cin >> s;
s == "usa"
Input stream content: americ england gana
//cin >> s;
s == "americ";
Input stream content: england gana
//etc.
while(true) {
    std::getline(std::cin, s)
    cout << "type : " << endl;
}

This might help you I'm trying to get inputs from a file by overloading the istream operator. For that, I declared it as friend of a class. Then, I take as input that same class like this: , This...
code :
while (!in.eof()) {
string name;
int age;
while (in >> name >> age)
    ...do stuff...
char dot;
string name;
int age;
while (in >> dot && dot == '.' && in >> name >> age)
    ...do stuff...

Hope that helps You don't have to use a $scope.$watch. You can do this by using ng-repeat over an array which has the same number of values as player count.
code :
var app = angular.module('testApp', []);
app.controller('testCtrl', function($scope) {
 $scope.player={"count":0};
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>

<body ng-app="testApp" ng-controller="testCtrl">
<input type="number" ng-model="player.count"/>
    <div>
            <div ng-repeat="player in  [].constructor(player.count) track by $index">
                <input id="player{{$index+1}}" type="text" class="form-control" placeholder="Enter name for player {{$index+1}}" ng-model="player.value" />
            </div>
      </div>      
</body>

this will help , You said
code :
istream& operator>> (istream& in, shuffle_mode shuffle) {
  in >> shuffle;
}
istream& operator>> (istream& in, shuffle_mode& shuffle) {
    std::string token;
    in >> token;
    if ( token == "IN" || token == "1" ){shuffle=IN;}
    else if ( token == "OUT" || token == "2" ){shuffle=OUT;}
    else { /* Error */ }

    return in;
}

will be helpful for those in need So what you basically want is to parse a const char* to retrieve a integer number inside it, and ignore all whitespace(+others?) characters.
Remember that characters like '1' or 'M' or even ' ' are just integers, mapped to the ASCII table. So you can easily convert a character from its notation human-readable ('a') to its value in memory. There are plenty of sources on ascii table and chars in C/C++ so i'll let you find it, but you should get the idea. In C/C++, characters are numbers (of type char).
