I wrote a c program in order to write 5 students records (name, ID and average)
to a file.
Now the difficult step is to firstly to find the highest average among students.
Have anyone any clue how I can do this?
why don't you share your code, so that i can modify it to give required result.
Yes, the Original Poster (OP) should share his code, but you do not modify it to get it to work. We do not approve of cheating. You can give suggestions on how to fix the code, but it's the OP's job to modify it to give the required result.
