C Program to Store Information in Structure and Display it | C Programming

Structure 

  Arrays are used to store large set of data and manipulate them, but the disadvantage is that all the elements stored in an array are to be of the same data type. If we need to use a collection of different data type items, it is not possible using an array. When we require using a collection of different data items of different data types, we can use a structure.  Structure is a method of grouping data of different types.  A structure is a convenient method of handling a group of related data items of different data types.  

Structure declaration: 

General format:   

struct tag_name{          

data type member1;   

data type member2;   

…   

};

C Program to Store Information in Structure and Display it

#include <stdio.h>
struct student
{
    char name[50];
    int roll;
    float marks;
} s[10];
int main()
{
    int i, n;
    printf("Enter how many students marks you want to store.\n");
    scanf("%d", &n);
    printf("Enter information of students:\n");
    // storing information
    for (i = 0; i < n; ++i)
    {
        s[i].roll = i + 1;
        printf("\nFor roll number%d,\n", s[i].roll);
        printf("Enter name: ");
        scanf("%s", s[i].name);
        printf("Enter marks: ");
        scanf("%f", &s[i].marks);
        printf("\n");
    }
    printf("Displaying Information:\n\n");
    // displaying information
    for (i = 0; i < n; ++i)
    {
        printf("\nRoll number: %d\n", i + 1);
        printf("Name: ");
        puts(s[i].name);
        printf("Marks: %.1f", s[i].marks);
        printf("\n");
    }
    return 0;
