作为成员变量的C++向量

我想使用向量作为成员变量。作为成员变量的C++向量

GameOfLife.h 
class GameOfLifeManager { 
    std::vector<Cell::Cell> cells; 
    ... 

GameOfLife.cpp 

... 
cells.push_back(Cell::Cell(x,y,false)); 
...

和Cells.h看起来像这样

#ifndef CELL_H_ 
#define CELL_H_ 

namespace Cell { 

class Cell { 

    bool alive; 

    int posX; 
    int posY; 

    Cell* left; 
    Cell* right; 
    Cell* top; 
    Cell* bottom; 

    Cell* topLeft; 
    Cell* topRight; 
    Cell* bottomRight; 
    Cell* bottomLeft; 

public: 

    Cell(int x, int y, bool alive); 

    int CountNeighbours(); 
    void Kill(); 
    void Resurrect(); 

}; 


} /* namespace Zell */ 
#endif /* CELL_H_ */

，如果我尝试调用cells.push_back(Cell::Cell(x,y,false))日食告诉我 “从这里需要”我也不能解密错误味精。任何想法出了什么问题？

你有C++ 11支持吗？否则，你的'GameOfLifeManager'类声明是错误的。 – juanchopanza

这也有点毫无意义，因为它会默认构建。 – chris

所以你知道，你不必说'std :: vector cells = {};' - 所做的只是创建一个空的向量，构造函数将会做任何事情。（除此之外，我大概有74％的人确信C++不允许你在声明这样的位置初始化对象，除非C++ 11在这方面发生了显着变化。） – cHao

它看起来像你有一个命名空间内#include语句。

不在您显示的代码中......可能在您的源文件中。
