/* Write a  C program to illustrate the concept of unions*/

#include <stdio.h>
#include <conio.h>

void main()
{
union number
{
int  n1;
float n2;
};

union number x;

clrscr() ;

printf("Enter the value of n1: ");
scanf("%d", &x.n1);
printf("Value of n1 =%d", x.n1);

    printf("\nEnter the value of n2: ");
scanf("%d", &x.n2);
printf("Value of n2 = %d\n",x.n2);

} /* End of main() */

/*------------------------------------
Output
Enter the value of n1: 2
Value of n1 =2
Enter the value of n2: 3
Value of n2 = 0
