Thread: pseudocode for functions

What is the standard or convention for functions in speducode

For example I have this. Would I specifically declare the variables as is? My attempt is below

Code:

void CB1::midpointline(int x0,int y0, int x1, int y1, CDC *pDc)	
{
	int dx,dy,incrE,incrNE,d,x,y;

	dx=x1-x0;
	dy=y1-y0;
	d=dy*2-dx;
	incrE=dy*2;
	incrNE=(dy-dx)*2;
	x=x0;
	y=y0;

}

Code:

Create function mindpointline(StartPoint x0 , StartPoint y0 , EndPoint x1 , EndPoint y1 , Pointer to Device Context)

   Set Delta(X) to x1-x0
   Set Delta(y) to y1-y0
   Set decision to 2*dy-dx
   set Delta(E) to dy*2
   set Delta(NE) to 2*(dy-dx)
   set x to equal x0
   set y to equal y0
   Draw pixel with X and Y values

End functiojn
