vector inside a class

[Lovens Weche]

I'm trying to compile this code with VC++ 7:

class KeyboardInterfa ce

{

public:

.....

std::vector<KBB its4KeyUp> KBKUBuffer(256, KBBuffer);

....

}

I get this error: error C2059: erreur de syntaxe : 'constant'

I guess we can't use the constructor of a vector in a class declaration,
right??? How can I solve this problem? thanx in advance...

A class declaration requires a semicolon.

class KeyboardInterfa ce
{
};

Lets consider a std::vector<int > and lets initialize a vector of 64
elements to 0 (hint: ctor initialization list)
---
// KeyboardInterfa ce.h
#ifndef KEYBOARDINTERFA CE_H_
#define KEYBOARDINTERFA CE_H_

#include <vector>

class KeyboardInterfa ce
{
std::vector<int > vn;
public:
KeyboardInterfa ce();
~KeyboardInterf ace();
int getIndex(const int& n) const;
int getSize() const;
};

#endif // include guard KEYBOARDINTERFA CE_H_
___

// KeyboardInterfa ce.cpp
#include "KeyboardInterf ace.h"

const int NBUFFER(64); // could have been a member

KeyboardInterfa ce::KeyboardInt erface() : vn(NBUFFER, 0)
{
}

KeyboardInterfa ce::~KeyboardIn terface()
{
}

int KeyboardInterfa ce::getIndex(co nst int& n) const
{
// error checking required: n must be less than NBUFFER
return vn[n];
}

int KeyboardInterfa ce::getSize() const
{
return vn.size();
}

// test.cpp
#include "KeyboardInterf ace.h"
#include <iostream>

int main()
{
KeyboardInterfa ce ki;
std::cout << "vn[0] = " << ki.getIndex(0) << std::endl;
std::cout << "vn[63] = " << ki.getIndex(63) << std::endl;
std::cout << "vector size = " << ki.getSize() << std::endl;

return 0;
}
