📝 Question
Consider a structure as follow:
struct stud_info
{
int rno;
char sname[30];
int marks;
};
Write a C program that accept details of N-students and display student's details in descending order on marks.✅ Solution:
#include <stdio.h>
struct stud_info
{
int rno;
char sname[30];
int marks;
};
int main()
{
struct stud_info s[50], temp;
int n, i, j;
printf("Enter number of students: ");
scanf("%d", &n);
// Input student details
for(i = 0; i < n; i++)
{
printf("\nEnter details of student %d\n", i + 1);
printf("Roll No: ");
scanf("%d", &s[i].rno);
printf("Name: ");
scanf("%s", s[i].sname);
printf("Marks: ");
scanf("%d", &s[i].marks);
}
// Sorting in descending order of marks
for(i = 0; i < n - 1; i++)
{
for(j = i + 1; j < n; j++)
{
if(s[i].marks < s[j].marks)
{
temp = s[i];
s[i] = s[j];
s[j] = temp;
}
}
}
// Display sorted student details
printf("\nStudent Details in Descending Order of Marks:\n");
printf("\nRoll No\tName\tMarks\n");
for(i = 0; i < n; i++)
{
printf("%d\t%s\t%d\n", s[i].rno, s[i].sname, s[i].marks);
}
return 0;
}
