Program on structure

Define a structure for student which include roll number,name,age and marks. Write a program to read and display the information of 3 students.

#include<stdio.h>
#include<string.h>
struct student
{
int rno;
char name[10];
int marks,age;
};
void main()
{
//assigning values to structure variable s1 using initialization
struct student s1={2,"Gandhi",89,18};
struct student s2,s3;
//assigning values to s2 using assignment operator.
s2.rno=5;
s2.marks=90;
s2.age=18;
strcpy(s2.name,"Ram ");
//reading values for s3 using standard input function.
printf("\n enter rno,name ,marks,age of student: ");
scanf("%d%s%d%d",&s3.rno,s3.name,&s3.marks,&s3.age);
printf("\n\n");
printf("Details of student 1:\n");
printf("\n roll number: %d",s1.rno);
printf("\n name :%s",s1.name);
printf("\n marks: %d",s1.marks);
printf("\n age: %d",s1.age);
printf("\n\n");
printf("Details of student 2:\n");
printf("\n roll number: %d",s2.rno);
printf("\n name :%s",s2.name);
printf("\n marks: %d",s2.marks);
printf("\n age: %d",s2.age);
printf("\n\n");
printf("Details of student 3:\n");
printf("\n roll number: %d",s3.rno);
printf("\n name :%s",s3.name);
printf("\n marks: %d",s3.marks);
printf("\n age: %d",s3.age);
}
