Dynamic Student Records

Medium Dynamic Memory Allocation

Solve in Playground →

Problem Statement

Write a C program to dynamically allocate memory for an array of student structures, read their details, and print them.

Input Format

First line: n. Next n lines: Roll (int), Name (string), Marks (float).

Output Format

Print each student's details.

Constraints

1 <= n <= 10

Sample Input

2
101 John 88.5
102 Alice 92.0

Sample Output

Roll: 101, Name: John, Marks: 88.50
Roll: 102, Name: Alice, Marks: 92.00

Explanation

Allocate heap memory for `n` structures using `malloc`, read instance data into pointers, print formatted labels, and free memory.

Starter Code

#include <stdio.h>
#include <stdlib.h>

struct Student {
    int roll;
    char name[50];
    float marks;
};

int main() {
    int n;
    if (scanf("%d", &n) == 1) {
        // Write your code here for dynamic student records
    }
    return 0;
}

Limits

Time Limit: 1s
Memory Limit: 256MB
