Sam*_*orn -3 c++ constructor vector c++17
我正在开发一个程序来帮助我进行世界建设，该计划会根据用户选择的国家（德语，拉丁语，东部）随机生成定居点（村庄，村庄，城镇，城市）。我已经集成了一种定居者生成系统，以在定居点中创建定居者，每个定居者使用构造函数并将结果作为对象保存在向量中，每个定居者均具有名称，年龄，性别和财富。不幸的是，该程序创建了一个完整的克隆种群，用相同名称，年龄等的移居者填充了载体。
我曾尝试在for循环中初始化Settler类的构造函数，但除了在您每次请求其中一个有关定居者的信息时，会导致获得一组不同的定居者之外，它没有做任何更改。

对于上下文，“ objSettlement”是指随机生成的“结算”实例，而“ .settlementQuantity”是表示结算人口的整数。
因此，当我创建一个有30个人的拉丁小村庄时，程序会创建一个包含30种情况的向量：“ Faustus Crispian，男性，现年41岁，财富较差。” 不管我输入的数字是0-29。
为什么矢量初始化会使数组中的所有对象都相同？
这个 ：
std::vector<Settler> objSettler(objSettlement.settlementQuantity, Settler(tempType, tempNation, tempNum));
创建一个具有objSettlement.settlementQuantity相同对象副本的向量Settler(tempType, tempNation, tempNum)。
有关各种向量构造器如何工作的详细信息，请参见此参考页。
这样的事情可能更接近您想要的东西：
std::vector<Settler> objSettler;
for (int i = 0; i < objSettlement.settlementQuantity; ++i) {
objSettler.emplace_back(tempType, tempNation, tempNum);
}
