  for loop examples in C++
    C++ / (Exercise) Student Information

    write c++ program that read information of N student
    in 3 class (English ,math computer) then calculate
    the average of each  student then print if student is
    passed to next class or fail
    note that student will passed to next class if and
    only got grade 50 or above in each subject
