Q.13 Write a program in C that accpets roll number and name of student’s of a class size of one hundred students along with the marks obtained by them in physics, Chemistry and Mathematics. Print roll number and the name of top ten students in the order of merit. The merit is based on the sum of the marks obtained in the three subjects. (AKTU. 2009-10)
Ans.
#include<stdio.h>
#include<conio.h>
#include<string.h>
#define size 100
void main()
{
int i, j;
struct student
{
int roll_no;
char name[30];
int physics;
int chemistry;
int maths;
int total ;
} temp, stu[size];
clrscr();
//Input
for( i = 0; i < size; i++)
{
printf("\nEnter the Information of student %d", (i + 1));
printf("\nName :");
scanf("%s",&stu[i].name);
printf("\nRoll_No.\n");
scanf("%d", &stu[i].roll_no);
printf("\nMarks in Physics\n");
scanf("%d", &stu[i].physics);
printf("\nMarks in Chemistry\n");
scanf("%d", &stu[i].chemistry);
printf("\nMarks in Maths\n");
scanf("%d", &stu[i].maths);
stu[i].total = stu[i].physics + stu[i].chemistry + stu[i].maths ;
}
//Sorting array using Bubble Sort
for( i = 0; i < size; i++)
{
for( j = 0; j < size; j++)
{
if(stu[j].total < stu[j + 1].total)
{
temp = stu[i];
stu[i] = stu[j + 1];
stu[j + 1 ] = temp;
}
}
}
//Output
printf("\nMerit List of top 10 students:\n");
for( i = 0; i < 10; i++)
{
printf("\nRank %d : ", ( i + 1 ));
printf("\nName :");
printf("%s",stu[i].name);
printf("\nRoll_No.");
printf("%d", stu[i].roll_no);
printf("\nTotal :");
printf("%d", stu[i].total);
}
getch();
}
