我需要将结构数组保存在二进制文件中。但是有一些问题!我的结构中有一些 3d 向量数组!这是我的结构:
struct State
{
vector<bool> ***value;
vector<int> ***rfcCLB2Bits;
State()
{
new3dArray(value , 60 , 100 , 2);
new3dArray(rfcCLB2Bits , 60 , 100 , 2);
}
};
你可能想看看 new3dArray 函数:
template <class T>
void new3dArray(T ***&u3d, int nx , int ny , int nz)
{
u3d = new T ** [nx];
if (NULL == u3d)
{
cout <<"erro3"<<endl;
}
else
{
for (int i = 0; i < nx; i++)
{
u3d[i] = new T *[ny];
if (NULL == u3d[i])
{
cout <<"erro4"<<endl;
}
else
{
for (int j = 0; j < ny; j++)
{
u3d[i][j] = new T [nz];
if (NULL == u3d[i][j])
{
cout <<"erro5"<<endl;
}
}
}
}
}
}
最后我的保存和加载代码:
int main()
{
State *states;
int k ;
cin >> k;
states = new State[k];
...
string location = "save1.bin";
ofstream fs(location, std::ios::out | std::ios::binary | std::ios::app);
fs.write(reinterpret_cast<const char *>(states), sizeof(states));
fs.close();
...
ifstream file (location, ios::in|ios::binary|ios::ate);
if (file.is_open())
{
file.seekg (0, ios::beg);
file.read ((char*)&states, sizeof(states));
file.close();
}
...
}
但它没有用!我必须做什么?
