The DS teacher wants to know the student of second highest mark in CT 1, if she has a ordered list of marks for 10 students.

#include <stdio.h>
struct student
{
  char name[20];
  int marks;
 }s[20],temp;


int main()
{
  int i,j;  
for(i=0;i<10;i++)
{
    scanf("%s %d",s[i].name,&s[i].marks);
  }
  for(i=0;i<10;i++)
  {
    for(j=0;j<10;j++)
    {
      if(s[j].marks<s[j+1].marks)
      {
        temp=s[j];
        s[j]=s[j+1];
        s[j+1]=temp;
      }
    }
  }
  printf("Ordered List\n");
  for(j=0;j<10;j++)
  printf("%s %d\n",s[j].name,s[j].marks);
  printf("Second Highest mark is %d",s[1].marks);
	return 0;
}
