vector as private data

**robquigley** · 12-01-2003

hey,

i'm just writing a small class now and i want a few vectors as private data. if i use the line

Code:

 	std::vector<int> a;

then there's no problem. But i want to declare that this vector should contain say, 32 elements, and that they are all initialise3d to 0, so i tried

Code:

 	std::vector<int> a(32, 0);

but it won't let me and errors with some

Code:

 error C2059: syntax error : 'constant'

How can i specify the size and initial contents of the vector?

I don't get any errors if i use code like this in an ordinary program. Is there something special happening here cause it's in the private data section of a class?

Any ideas would be great.

just try specifying in the constructor

run a loop in the constructor that does it for ya

You can't call constructors directly in the class declaration, you must do it in the constructor chain of the class constructor.

Code:

class mine {
  std::vector<int> vec;
public:
  mine() : vec(32) {}
};
