In C/C++, a structure is a user-defined data type. A structure provides a data type that can be used to combine objects of different types into a single type.

The keyword "struct" is used to specify a structure. "struct" is a new data type that is a collection of various data types. Structure variables can be defined either as part of the structure declaration or as a separate declaration, similar to basic types.

struct structure_name





How Will You Access Structure Elements?

The elements from the structure can be accessed using (.) Dot Operator.

Programm To Store Students Information Using Structure:

#include <stdio.h>

struct student {
    char first_name[50];
    char last_name[50];
    int roll_number;
    char grade [10];
} s[50];

int main() {
    int x, i;
    // x is the total no. of students

    printf("Enter the number of students: ");
    scanf("%d", &x);
    // To store the student's information
    printf("\nEnter the students's informations:\n");
    for (i = 0; i < x; i++) {
        s[i].roll_number = i + 1;
        printf("\nInformation for Roll Number:\t%d\n", s[i].roll_number);

        printf("Enter the first name: ");
        scanf("%s", s[i].first_name);

        printf("Enter the last name: ");
        scanf("%s", s[i].last_name);

        printf("Enter the Grade: ");
        scanf("%s", s[i].grade);

    // To display the student's information
    printf("\n\nDisplay the student's information:\n");
    for (i = 0; i < x; i++) {
        printf("\nThe Roll Number:\t%d\n", i + 1);

        printf("The Last Name: ");

        printf("The Grade: ");
