Explanation

Sorts structures by marks descending.

Starter Code

#include <stdio.h>

struct Student {
    char name[51];
    float marks;
};

int main() {
    int n;
    if (scanf("%d", &n) == 1) {
        struct Student s[n];
        for (int i = 0; i < n; i++) scanf("%50s %f", s[i].name, &s[i].marks);
        // Write your code here
    }
    return 0;
}
