Help Needed On Classes

Making a 2D game. this part of the code should move a texture randomly over a textured background, use clipping/blitting to draw the texture partially off the screen and use transparency on the texture.

Here's my class declaration & member-function definitions ( which are saved in different files)

Code:

---

//rectangle class
class CRect {
               
public:
  //constructor & destructor 
  CRect(){ left = right = top = bottom = 0;}       
    ~ CRect(){};

    CRect (int l, int r, int t, int b ) : left (l), right (r), top (t), bottom (b) {};
    CRect (const CRect &otherRect):left (other.left), right (other.right), top (other.top), bottom (other.bottom) {};

    //functions for returning width & height
    int sourceWidth () const {return right-left;}
    int sourceHeight () const {return top-botton;}

private:
    int left, right, top, bottom;

};

///////////////////////////////////////////////////////////////////////////////

#include "Crect.h"

 //function to clip source rectangle against destination rectangle
void ClipFn ( BYTE *destination, int destWidth, const CRect &destRect, BYTE *source, int sourceWidth, const CRect &sourceRect, int posX, int posY )
{
CRect newSourceRect ( 0, sourceRect.Width(), 0, sourceRect.Height() );
                       
source.left + posX, source.right + posX, source.top + posY, source.bottom + posY;

                                       
if (otherRect.left > left )
  left = otherRect.left;
if (otherRect.right < right )
  right = otherRect.right;
if (otherRect.top > top )
  top = otherRect.top;
if (otherRect.bottom < bottom )
  bottom = otherRect.bottom;

source.left - posX, source.right - posX, source.top - posY, source.bottom - posY;


newSourceRect.left += sourceRect.left;
newSourceRect.right += sourceRect.left;
newSourceRect.top += sourceRect.top;
newSourceRect.bottom += sourceRect.top;

//call to blitting function
BlitFn ( destination, source, destWidth,  sourceWidth, newSourceRect, newPosX, newPosY );

}

////////////////////////////////////////////////////////////////////////////////////

//duno where to implement this bit - think it should be a member function of class and used there.
void clip ( const CRect &sourceRect )
{
  result = source;

  if ( source.right + posX > destination.right )
        result.right = destination.right - posX;
       
  if ( source.bottom + posX > destination.bottom )
        result.bottom = destination.bottom - posY;
}

Biggest problem is in the class declaration where there are 9 errors in the one line as 'other' is undeclared and therefore all the members (left,right,top&bottom)of 'other' have no type.

Code:

---

CRect (const CRect &otherRect):left (other.left), right (other.right), top (other.top), bottom (other.bottom) {};

---

any ideas on how to fix this?
also anybody know where i should implement the clipping & blitting functions within my game loop?

Code:

CRect (const CRect& otherRect):left (other.left), right (other.right), top (other.top), bottom (other.bottom) {};
