Students Information Using Structure

On this page we will write C program to store students information using structure . Structure is an user defined data type that can be used to group elements of heterogeneous type into a singe type.This program will help to understand the basics and working of structure data type and C programming.

Store Students Information Using Structure in C

Structure is an user defined data type that can be used to group elements of different type into a single type.We can access the members of structure by using a variable or we can say by creating an object of structure.Structure data type is declared using ‘struct‘ keyword.

Syntax:

struct structure_name
{
//Statements
};

In Student Information we can include:

Name
Roll Number
Age
Address
Total Marks
Date of birth

Example:

struct Student
{ 
   char* name; 
   int roll_number;
   int age;
   double total_marks;
};

Program 1:

Run

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

struct Student
{
  char *name;
  int roll_number;
  double marks;
} s[3];

int main ()
{
  int i = 0;

  s[0].roll_number = 1;
  s[0].name = "Aashay";
  s[0].marks = 89;

  s[1].roll_number = 2;
  s[1].name = "Bhavya";
  s[1].marks = 77;

  s[2].roll_number = 3;
  s[2].name = "Chetan";
  s[2].marks = 92;

  printf ("Student Records:\n\n");
  for (i = 0; i < 3; i++)
    {
      printf ("\tName = %s\n", s[i].name);
      printf ("\tRoll Number = %d\n", s[i].roll_number);
      printf ("\tMarks = %0.2f\n\n", s[i].marks);
    }

  return 0;
}

Output:

Student Records:

	Name = Aashay
	Roll Number = 1
	Marks = 89.00

	Name = Bhavya
	Roll Number = 2
	Marks = 77.00

	Name = Chetan
	Roll Number = 3
	Marks = 92.00

Program 2:

Run

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

struct Student
{
  char *name;
  int roll_number;
  int age;
  double total_marks;
};

int main ()
{
  int i = 0;
  struct Student s[4];

  s[0].roll_number = 1;
  s[0].name = "Aman";
  s[0].age = 16;
  s[0].total_marks = 89.50;

  s[1].roll_number = 7;
  s[1].name = "Bharat";
  s[1].age = 15;
  s[1].total_marks = 90;

  s[2].roll_number = 12;
  s[2].name = "Saksham";
  s[2].age = 17;
  s[2].total_marks = 72.50;

  s[3].roll_number = 27;
  s[3].name = "Vivek";
  s[3].age = 16;
  s[3].total_marks = 66;


  printf ("Student Records:\n\n");
  for (i = 0; i < 4; i++)
    {
      printf ("\tName = %s\n", s[i].name);
      printf ("\tRoll Number = %d\n", s[i].roll_number);
      printf ("\tAge = %d\n", s[i].age);
      printf ("\tTotal Marks = %0.2f\n\n", s[i].total_marks);
    }

  return 0;
}

Output:

Student Records:

	Name = Aman
	Roll Number = 1
	Age = 16
	Total Marks = 89.50

	Name = Bharat
	Roll Number = 7
	Age = 15
	Total Marks = 90.00

	Name = Saksham
	Roll Number = 12
	Age = 17
	Total Marks = 72.50

	Name = Vivek
	Roll Number = 27
	Age = 16
	Total Marks = 66.00

In the above program we created a structure with name student using ‘struct’ Keyword.
To access the members of structure student we created structure array s[4] which can store the information of 4 students
using dot(.) operator we can access the members of struct. For eg: s[i].roll_number=1.
Similarly using for loop we can print all the stored student information.
