Example of structure and union

#include<stdio.h>
#include<conio.h>
union student2
{
    int roll;
    char name[20];
    float age;
}s2;
int main()
{
    //clrscr();
    printf("Enter roll ");
    scanf("%d",&s2.roll);
    printf("Enter name ");
    scanf("%s",s2.name);
    printf("Enter age ");
    scanf("%f",&s2.age);
    printf("Roll number %d\n",s2.roll);
    printf("Name %s\n",s2.name);
    printf("Age %f\n",s2.age);
    getch();
    return(0);
}

/* Output */
Enter roll 101
Enter name aaa
Enter age 15
Roll number 
Name
Age 15.000000
