关于vector的赋值问题，急等!
小弟初用vector,写了一段程序做测试用
typedef double seed[3];
seed s[5] = { {0,0,0},{1,1,1},{2,2,2},{3,3,3},{4,4,4} };
std::vector <seed> vec;
for(int i=0;i <5;i++)
{
vec.push_back(s[i]);//提示这儿有错
}
... ...
错误提示很奇怪，小弟从没见过：e:\program files\microsoft visual studio\vc98\include\xutility(39) : error C2440: '= ' : cannot convert from 'const double [3] ' to 'double [3] '
There is no context in which this conversion is possible
e:\program files\microsoft visual studio\vc98\include\vector(170) : see reference to function template instantiation 'void __cdecl std::fill(double (*)[3],double (*)[3],const double (&)[3]) ' being compiled
e:\program files\microsoft visual studio\vc98\include\xutility(25) : error C2106: '= ' : left operand must be l-value
e:\program files\microsoft visual studio\vc98\include\vector(174) : see reference to function template instantiation 'double (*__cdecl std::copy_backward(double (*)[3],double (*)[3],double (*)[3]))[3] ' being compiled

e:\program files\microsoft visual studio\vc98\include\xmemory(66) : see reference to function template instantiation 'void __cdecl std::_Construct(double (*)[3],const double (&)[3]) ' being compiled
Error executing cl.exe.
希望能得到高手的指导，上述向量应该怎么赋值？多谢！！！
[解决办法]
typedef double seed[3];
seed s[5] = { {0,0,0},{1,1,1},{2,2,2},{3,3,3},{4,4,4} };
std::vector <seed> vec;
for(int i=0;i <5;i++)
{
vec.push_back(s[i]);//提示这儿有错
}

个人觉得用结构体为vector中的元素比较好点.
struct seed
{
double dd1;
double dd2;
double dd3;
};
std::vector <seed> vec;
for(int i=0;i <5;i++)
{
seed s;
s.dd1 = i;
s.dd2 = i;
s.dd3 = i;
vec.push_back(s);//
}
[解决办法]
用两个vector也可以实现吧
typedef std::vector <int> seed;
int main()
{
std::vector <seed> vec;
for(int i=0;i <5;i++)
{
seed tmp;
tmp.push_back(i);
tmp.push_back(i);
tmp.push_back(i);
vec.push_back(tmp);
}
}
push_back的原型是void vector::push_back(const _TYPE& _X)，参数是引用类型，所以数组是不可以的
