Hi, i have the following structure:


struct Matrix3D
{
	//3 coloum vectors
	Vector3D C[3];

	//ctor - identity matrix
	Matrix3D():C[0].x(1), C[1].y(1), C[2].z(1){}
	//ctor - user defined
	Matrix3D(const Vector3D &c0, const Vector3D &c1, const Vector3D &c2)
		:C[0](c0),
		 C[1](c1),
		 C[2](c2)
	{}
...
...
};

but in both of the ctors i get the error: c:\documents and settings\daniel lowengrub\my documents\visual studio 2005\projects\physic\physic\physic\Matrix3D.h(16) : error C2059: syntax error : '[' What's the problem? Thanks.

You can't construct the elements of an array in an initializer list like that. Just do it in the body of the constructor.

struct Matrix3D{	//3 coloum vectors	Vector3D C[3];	//ctor - identity matrix	Matrix3D()        {            C[0].x = 1;            C[1].y = 1;            C[2].z = 1;        }	//ctor - user defined	Matrix3D(const Vector3D &c0, const Vector3D &c1, const Vector3D &c2)        {            C[0] = Vector3D(c0);            C[1] = Vector3D(c1);            C[2] = Vector3D(c2);	}......};
