Decision Making and Looping

A class of n students take an annual examination in m subjects. A program to read the marks obtained by each student in various subjects and to compute and print the total marks obtained by each of them is given.

#include <stdio.h>
#define FIRST   360
#define SECOND  240
void main()
   {
       int n, m, i, j,
    roll_number, marks, total;
       printf("Enter number of students and subjects\n");
       scanf("%d %d", &n, &m);
       printf("\n");
       for (i = 1; i <= n ; ++i)
       {
    printf("Enter roll_number : ");
    scanf("%d", &roll_number);
    total = 0 ;
printf("\nEnter marks of %d subjects for ROLL NO %d\n",
m,roll_number);
    for (j = 1; j <= m; j++)
    {
        scanf("%d", &marks);
        total = total + marks;
    }
    printf("TOTAL MARKS = %d ", total);
    if (total >= FIRST)
        printf("( First Division )\n\n");
    else if (total >= SECOND)
     printf("( Second Division )\n\n");
  else
     printf("( ***  F A I L  *** )\n\n");
       }
       getch();
   }
