Problem Statement

Write a C program using a structure to store a student’s roll number, name, and marks, then print them.

Input Format

An integer roll number, a string name, and a float marks separated by spaces/newlines.

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

int main() {
    struct Student s;
    if (scanf("%d %50s %f", &s.roll, s.name, &s.marks) == 3) {
        // Write your code here
    }
    return 0;
