Answer 1

Please check the programme which will accpet the Number of students input

and then you have to Enter the Marks for N number of students,

in the output it will show the Average marks of the class, and student wise below and above average marks

PROGRAMM

#include<stdio.h>
#include<conio.h>

struct class{
int marks;
}st[15];
void main()
{
int i,n;
float total=0,Avgmarks;
//clrscr();
printf("\nEnter the number of students in the class(<=15):");
scanf("%d",&n);
for(i=0;i<n;i++)
{
printf("\nEnter student %d marks :",i+1);
scanf("%d",&st[i].marks);
}
for(i=0;i<n;i++)
{
total = total + st[i].marks;
}
Avgmarks=total/n;
printf("\nAverage marks of the class = %.2f",Avgmarks);
for(i=0;i<n;i++)
{
if(st[i].marks>=Avgmarks)
{
printf("\n student %d marks = %d above the average",i+1,st[i].marks);
}
else
{
printf("\n student %d marks = %d below the average",i+1,st[i].marks);
}
}
getch();
}
