#include <stdio.h>
#include <stdlib.h>
 
int main()
{
    // counters
    int i;
    int j;
 
    // amount of students
    int n;
    // students marks,mark[i][8] equals average
    float mark[10][9] = {};
 
    // marks are read
    printf("Enter the amount ofstudents: ");
    scanf("%d", &n);
    for(i = 0; i < n; i++) {
        printf("Student %d marks:", i + 1);
        for (j = 0; j < 8; j++) {
           scanf("%f", &mark[i][j]);
 
           mark[i][8] += mark[i][j];
        }
       mark[i][8] /= 8;
    }
 
    //table is outputted
    printf("no OIT111 OIT112OIT113 OIT114 OIT115 OIT116 OIT117 OIT119 Total Average\n");
 
    for(i = 0; i < n; i++) {
       printf("%-3d", i + 1);
        for (j = 0; j < 8; j++) {
           printf("%5.2f  ", mark[i][j]);
        }
       printf(".2f \n", mark[i][8]);
    }
 
    return 0;
