C Program to Store Information of a Student Using Structure

Introduction

In this C programming tutorial, we will create a program to store information about a student using a structure. A structure is a composite data type in C that allows you to group variables of different data types under a single name. We will design a structure to represent student details, take input from the user, store the information, and display it. The algorithm, C code, and explanation will be provided.

Understanding the Algorithm

The algorithm for the program involves the following steps:

1. Define Structure: Create a structure to hold information about a student, including attributes like name, roll number, marks, etc.
2. Input Student Information: Accept details of a student such as name, roll number, and marks from the user.
3. Store Information: Create a variable of the structure type and store the input information in that variable.
4. Display Information: Print or display the stored information about the student.

C Program for Storing Student Information

#include <stdio.h>

// Define structure for student information
struct Student {
    char name[50];
    int rollNumber;
    float marks;
};

int main() {
    // Declare a variable of the structure type
    struct Student student;

    // Input student information
    printf("Enter student details:\n");
    printf("Name: ");
    fgets(student.name, sizeof(student.name), stdin);
    printf("Roll Number: ");
    scanf("%d", &student.rollNumber);
    printf("Marks: ");
    scanf("%f", &student.marks);

    // Display student information
    printf("\nStudent Information:\n");
    printf("Name: %s", student.name);
    printf("Roll Number: %d\n", student.rollNumber);
    printf("Marks: %.2f\n", student.marks);

    return 0;
}

Output Example

Example: Input and Display Student Information

Enter student details:
Name: John Doe
Roll Number: 12345
Marks: 85.5

Student Information:
Name: John Doe
Roll Number: 12345
Marks: 85.50

Explanation

1. Structure Definition: We define a structure named Student with attributes name, rollNumber, and marks.
2. Input: The program prompts the user to input details like name, roll number, and marks using printf and scanf functions.
3. Storing Information: An instance of the structure Student named student is declared, and the input information is stored in it.
4. Display: The program then displays the stored information using printf.

Conclusion

This C program demonstrates the use of structures to store information about a student. You can extend this program to include additional attributes or create an array of structures to store information for multiple students.
