Post any relevant code (You may choose to attach the file instead of posting the code if it is too long)

var students : int
var passinggrade : int
var finalgrade: int
var counter: int

for i: 1..10 by 1
end for
counter := 1 %Initialize

put "Input the number of students :"..
get students

loop
put "Enter the passing code for a course: "
get passinggrade
put "Enter mark for student: ", counter
get finalgrade
if finalgrade >= passinggrade then
put "Student passes"
put ""
else
put "Student fails"
put ""
end if
exit when counter >= students %Test
counter := counter + 1 %Update

end loop

Have you tried anything?

I am trying this accumaltor thing but its not working. I do not know what to put like if we need a counter or variable

Forget about computers for a moment -- how would you handle the task? If you were physically handed a stack of papers with grades, what steps would you use to accomplish the same task?

I would keep the passed marks on one side and the failed ones on the other.

That's a start, but it gives you two piles, and not the "count". What else would you do?

tally the students who have passed and failed on a piece of paper

That is a good approach.

In this case, a "piece of paper" is a place where you record/remember information -- similar to variables.

"Tally" would be the process of incrementing a value in a variable.

You can take the ideas that you came up with, and try to describe them in Turing's language.

Turing:

var passing_students : int := 0 % keep track of passing students; initially none

..
passing_students := passing_students + 1 % tally one more passing student

var students : int
var passinggrade : int
var finalgrade: int
var counter: int
var passing_students : int := 0 % keep track of passing students; initially none
var failing_students : int := 0 % keep track of failing students; intiitally none

for i: 1..10 by 1
end for
counter := 1 %Initialize

put "Input the number of students :"..
get students

loop
put "Enter the passing code for a course: "
get passinggrade
put "Enter mark for student: ", counter
get finalgrade
if finalgrade >= passinggrade then
put "Student passes"
put ""
else
put "Student fails"
put ""
end if
exit when counter >= students %Test
counter := counter + 1 %Update
passing_students := passing_students + 1
failing_students := passing_students + 1
end loop

You've got the right pieces, but not in the right order. How would you follow those instructions?

Turing:

if finalgrade >= passinggrade then % if <condition to pass>
put "Student passes" % say "Student passes"
else % otherwise
put "Student fails" % say "Student fails"
end if

exit when counter >= students % stop doing anything after N times

counter := counter + 1 % keep track of how many times the above was done

passing_students := passing_students + 1 % tally 1 for passing students
% and also
failing_students := passing_students + 1 % tally 1 for failing students


You might notice that in such a setup both tallies will always be the same.

so we will need variables for passing_grade and failing_grade
