  a)  Find the coefficients of a curve, 
      that passes through three, four, five points.    

  b)  Find the coefficients a, b, c, d, e of a conic,
          ax**2 + by**2 + cx + dy + e  = 0 
      that passes through  four points.  

  c)  Find the coefficients a, b, c, d  of a circle,
          ax**2 + ay**2 + bx + cy + d  = 0   
      that passes through  three points. 
 

 I have used gcc.2.9 (Dev-C++ 4), 
             gcc.3.2 (v2DJGPP Rhide).
