I'm a novice.

I want to read two pairs of values from a simple file (that can be positive or negative) to determine which are the lowest and highest. The file is just that, a series of values, however teh first one is an x co-ordinate and the second a y co-ordiante.

I have some code that works for a single value, how do I mod it for two.

  maxheight = 0;
  while (file1>>height){
   if (height>maxheight)

This code extracts one value for height and determines the max value. teh file I am looking at detemines heading.

I know this is scandously overpriced in terms of points, but I need help and we're thick in th UK. And yes, it's a college assignment ........

  #include <limits.h>

  int width;

  points = 0;
  maxheight = INT_MIN;
  maxwidth = INT_MIN;
  minheight = INT_MAX;
  minwidth = INT_MAX;
  while ( (file1>>height) && (file1>>width) )
    if ( height > maxheight )
       maxheight = height;

    if ( height < minheight )
       minheight = height;

    if ( width > maxwidth )
       maxwidth = width;

    if ( width < minwidth )
       minwidth = width;

Hope that helps,
