Structures abov below avg ALG

Start
Declare the required variables
Read number of students as n
for each student read the name, usn and marks and store it in structure stud
stud.name = name
stud.usn = usn
stud.marks = marks
total = total + marks
avg = total/n
j = 0
k = 0
for i = 0 through n-1 do
      if(stud[i].marks > avg)
             aboveavg[j++] = i
      else belowavg[k++] = i
Display students above the average
for i = 0 through j -1 do
display stud[aboveavg[i]].name,  stud[aboveavg[i]].marks
Display students below the average
for i = 0 through k -1 do
display stud[belowavg [i]].name,  stud[belowavg [i]].marks
Stop
