Array of Structure

As we have an array of basic data types, same way we can have an array variable of structure.

Suppose we want to store details of 50 students instead of declaring 50 different variables of student type, we can declare an array of size 50 to store details of 50 students.

Example:

            struct student

            {

                        int id;

                        char name[30];

                        float per;

            };

            struct student s[50];

Program:

A C Program to enter the records of 5 students using structure.

#include<stdio.h>

#include<conio.h>

struct stdinfo

{

            int rn;

            float per;

};

void main()

{

            struct stdinfo s[3];

            int i;

            clrscr();

                       

            for(i=1;i<=3;i++)

            {

                        printf("\n Enter the student roll no.:");    

                        scanf("%d",&s[i].rn);

                        printf("\n Enter the student percentage.:");         

                        scanf("%d",&s[i].per);

            }

for(i=0;i<=5;i++)

{

            printf("\n Roll Number \t\t Percentage");

            printf("\n %d \t\t %f",s[i].rn,s[i].per);

}

getch();

}         

OUTPUT:

Enter the student roll no.: 1

Enter the student percentage.: 67

Enter the student roll no.: 2

Enter the student percentage.: 76

Enter the student roll no.: 3

Enter the student percentage.: 88

Roll Number        Percentage
       1                      67
       2                      76
       3                      88
