Skip first 9 lines of file.

[luckyyyyyy]

I appriate your work but...
guys i have another problm.....i wana skip first 9 lines from my data file and after skipping i wana read x,y,z at the end of file. i did but after while loop is end it again skip these 9 lines. how to solve this.

and also i wana distinguish these float data and unsigned data, as you can see in data file. after 9 lines, 6 lines are the float data, after this 6 lines are unsigned int.

actually this file has a point data information. float information are the vertices and int. infromation are the faces information.
this is the data...

It is extremely rude to hijack someone else's thread, especially when you don't use code tags or anything else. I will split it off this time, but read through our Posting Guidelines, and follow them if you want to use this site.

Keep 9 lines in buffer (don't print them out or manipulate them), and then check for eof.

and also i wana distinguish these float data and unsigned data, as you can see in data file. after 9 lines, 6 lines are the float data, after this 6 lines are unsigned int.

You can parse lines with strtok()

thanks.....

and yes i got it...the right code is this...
full code removed---------------------
but how to distiguish float and int values in this data...i want to store float values in GLpoint struct...and int values in GLface struct.......wh en it read it makes no any difference to float and int..
for example...
if (the end of float value)
then
read the int values and store in GLface struct...

What's in the float's that's not in the ints?

first six lines have values float x,y,z, . and last six has unsigned int fx,fy,fz...I wana store first six in x,y,z, and last six in fx,fy,fz. when reading this file...how to do this...i think there should be a if command....if (float vaues) then this....if(int value) then this...

You hijacked someone else's thread - I split it off. You did not use code tags, I filled them in for you. Thank you for reading the Guidelines, please follow them in your future posts.

Okay, so is it like that every time? Can you ahrd code the first 6 to be floats and the last six to be unsigned ints?

If not, then you have to look for patterns in the data. You can read text in different ways, I'm suggesting to read it in as a string and parse the string for something that the floats have that the unsigned ints don't. From there, you can do whatever you want with it - you have your if condition that will report true or false.
