Final Project: Student Records System

Final Project — You've made it to the end!

Build a Complete Student Records System

This is the capstone challenge — you'll combine structs, dynamic memory, and file I/O into a fully functional student records system. Everything you've learned in this course comes together here.

YOUR TASK

Write a C program that:

Defines a struct Student with: name (char[50]), id (int), grade (float)
Reads n students from stdin
Writes all records to students.txt
Re-reads the file and prints each student as:
ID: X | Name: Y | Grade: Z.XX
Prints the class average grade at the end

Need a hint?

Step-by-step:
1. Define: typedef struct { int id; char name[50]; float grade; } Student;
2. Read n, then use malloc(n * sizeof(Student))
3. For each student: scanf("%d %s %f", &s[i].id, s[i].name, &s[i].grade);
4. Write to file: fprintf(f, "%d %s %.2f\n", s[i].id, s[i].name, s[i].grade);
5. Re-read and print: printf("ID: %d | Name: %s | Grade: %.2f\n", ...);
6. Compute average and print: printf("Average: %.2f\n", avg);
7. Always free(students); and fclose(f);

Example (input: 2, then "1 Alice 92.5", "2 Bob 78.0"):

ID: 1 | Name: Alice | Grade: 92.50
ID: 2 | Name: Bob | Grade: 78.00
Average: 85.25
