    scanf returns the number of items assigned,EOF means end-of-file and has value -1,so this statement probably means run the loop 2 times.

    *Please correct me,if I am wrong

    This statement simply means keep on scanning the values of m and n until End of File is reached.
    Scanf returns number of variables scanned normally but it returns EOF if End of File is reached before variables could be scanned.😀

    scanf :- used to scan the values.
    EOF:- indicates the End Of File.
    != :- relational operator (not equal to)
    this can be understood like this :-
    keep scanning the values in variables n and m from the file until EOF has not been found.
