my problem

hi,
i'm new to C programming and need a starting point for my problem.
i've got a GIS data file containing a list of points(x and y value on each line, each go to 2 decimal points). i need to read the file and store it in buffer, then find max and min values of x and y.

i don't know what to do!

Read them as floats using cin. Read until EOF ( .eof() ) is encountered. Then do a for loop though the buffer looking for the max resp. the min value.

ok thanks, but how do i distuinguish between the x and y values, they are separated by a space in the GIS file

Code:

---

float X;
float Y;

cin >> X >> Y;

---

This will read two floats from the file, whether there are spaces or newlines inbetween.

cheers, i'll give it a try!
