Answer 1

first rule of Discussion box show your attempt.

#include<stdio.h>
struct student
{
int rollno;
char name[20];
char college[40];
int score;
};
int main()
{
struct student s[20],temp;
int i,j,n;

printf("\nEnter no. of Students : ");
scanf("%d",&n);
printf("\nEnter the rollno,name,college name,score ");
for(i=0;i<n;i++)
scanf("%d%s%s%d",&s[i].rollno,s[i].name,s[i].college,&s[i].score);
for(i=0;i<=n-1;i++)
{
for(j=0;j<=n-1;j++)
{
if(s[j].score<s[j+1].score)
{
temp=s[j];
s[j]=s[j+1];
s[j+1]=temp;
}
}
}
printf("\nThe Merit List is :\n");
for(j=0;j<n;j++)
printf("%d\t%s\t%s\t%d\n",s[j].rollno,s[j].name,s[j].college,s[j].score);
return 0;
}

I assume you know the sorting algorithms, you can make the sort functions (bubble and its friends), and use pointer to a function, stores it in an array so when you choose the sorting method, it will directly calls the function. The hard thing is, to use it, the functions must have the same number of parameters. Optionally, use if-else or switch-case.
