C Program Using student_record Structure to Store and Display Student Details

In C programming, structures help you manage related data efficiently. This tutorial demonstrates how to define a structure student_record to hold a student’s name, branch, and total marks, and how to read and display the details for 10 students.

---

Objective

• Define a structure student_record with:
  • name (string)
  • branch (string)
  • total_marks (float or int)
• Input details for 10 students.
• Print all student records in a structured format.

---

Structure Definition: student_record

struct student_record {
    char name[50];
    char branch[30];
    float total_marks;
};

Full C Program Example

#include <stdio.h>

#define SIZE 10

// Define structure
struct student_record {
    char name[50];
    char branch[30];
    float total_marks;
};

int main() {
    struct student_record students[SIZE];

    // Input student data
    for (int i = 0; i < SIZE; i++) {
        printf("\nEnter details for Student %d\n", i + 1);
        printf("Name: ");
        scanf("%s", students[i].name);

        printf("Branch: ");
        scanf("%s", students[i].branch);

        printf("Total Marks: ");
        scanf("%f", &students[i].total_marks);
    }

    // Display student data
    printf("\n--- Student Records ---\n");
    for (int i = 0; i < SIZE; i++) {
        printf("\nStudent %d:\n", i + 1);
        printf("Name       : %s\n", students[i].name);
        printf("Branch     : %s\n", students[i].branch);
        printf("Total Marks: %.2f\n", students[i].total_marks);
    }

    return 0;
}

Sample Output

Enter details for Student 1
Name: Ravi
Branch: CSE
Total Marks: 455.75

...

--- Student Records ---

Student 1:
Name       : Ravi
Branch     : CSE
Total Marks: 455.75

Key Concepts Used

• Structure arrays in C.
• Reading multiple fields using scanf.
• Iterating with loops for data input/output.

---

Pro Tips

• Use fgets() for names with spaces.
• Convert marks to percentage format if needed.
• Create functions for input/output to make the code modular.

Conclusion

By using the student_record structure, you can group and manage multiple attributes of a student efficiently. This is especially useful for applications like student management systems or academic software.

This program is a great example of how to store and retrieve structured data using arrays of structures in C.
