Store and print user details using array (Real-world example) Program Code

#include <stdio.h>
int main() {
    int n, i;
    printf("Enter number of students: ");
    scanf("%d", &n);
    
    int roll[n];
    char name[n][50];
    float marks[n];
    
    // Input details
    for(i = 0; i < n; i++) {
        printf("\nStudent %d:\n", i+1);
        printf("Enter roll number: ");
        scanf("%d", &roll[i]);
        printf("Enter name: ");
        scanf("%s", name[i]);
        printf("Enter marks: ");
        scanf("%f", &marks[i]);
    }
    
    // Display details
    printf("\n\n========== STUDENT DETAILS ==========\n");
    printf("Roll\tName\t\tMarks\n");
    printf("------------------------------------\n");
    for(i = 0; i < n; i++) {
        printf("%d\t%s\t\t%.2f\n", roll[i], name[i], marks[i]);
    }
    
    return 0;
}
