}The program counts the number of terms in the file "scores.txt".
An end-of-file-controlled loop is used to read values until the end of file is encountered.
This sort of loop uses the fact that a file goes into the fail state when you try to read a
data value beyond the end of a file to control it.
The value of "temp" will be 6 at the end of the program but it was 0 at the beginning. The
value of temp is determined by its placement in the end-of-file controlled loop whereby
it loops once for every individual term it encounters and adds the value of 1 for
each. After each iteration it checks with the condition enclosed within the parentheses
that "feof(scorefile) . . ."
Is there a better, more economical way of saying this (the file has 6 values within it)?
Thanks for viewing :)
