Program to maintain student details using structures

Program:

#include<stdio.h>
#include<conio.h>
struct stud
{
    int rollno, s1, s2, tot;
    char name[10];
    float avg;
} s[10];
void main()
{
    int i, n;
    clrscr();
    printf("Enter the number of students : ");
    scanf("%d", &n);
    for(i = 0; i < n; i++)
    {
        printf("\nEnter the roll number : ");
        scanf("%d", &s[i].rollno);
        printf("\nEnter the name : ");
        scanf("%s", s[i].name);
        printf("\nEnter the marks in 2 subjects : ");
        scanf("%d %d", &s[i].s1, &s[i].s2);
        s[i].tot = s[i].s1 + s[i].s2;
        s[i].avg = s[i].tot / 2.0;
    }
    printf("\nRoll No. Name \t\tSub1\t Sub2\t Total\t Average\n\n");
    for(i = 0; i < n; i++)
    {
        printf("%d \t %s \t\t %d \t %d \t %d \t %.2f \n", s[i].rollno,s[i].name,s[i].s1,s[i].s2,s[i].tot,s[i].avg);
    }
    getch();
}

Output:

Enter the number of students : 2
Enter the roll number : 101
Enter the name : Arun
Enter the marks in 2 subjects : 75 85
Enter the roll number : 102
Enter the name : Babu
Enter the marks in 2 subjects : 65 75
 Roll No.  Name  Sub1  Sub2  Total  Average
  101     Arun   75    85     160   80.00
  102     Babu   65    75     140   70.00
