c++ - Convert 2d array to 1d array for drawing line -

As the LPD 3D accline accepts only 1D, I convert the 2D array to 1d array. Therefore, I can keep the line drawn on the screen and want to draw another new line.

  D3DXVECTOR2 lineVertices [newLine] for [currentLine] (int i = 0; i & lt; noOfNewLine; i ++) line - & gt; Draw (linewirt [i], 2, d3d caller_xrobj (0, 0, 0));   
 If I change  
  in line D3DXVECTOR2 [currentLine] [newLine]   
 I  
  lineVertices [i]   
 to successfully convert it to 1d array?   
 
 
 Why do you need to change 2d in 1d? Any array in C \ C ++ is stored in memory as 1d allready, just assign an address to AMS before an indicator  
  p = & amp; Lines [0] [0];   
 Where  p  is an indicator for your array type. And then repeat with  p   
  (int i = 0; i & lt; newLine * currentLine; i ++) {// do stuff with P [i]}
