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

union u
{
    char c;
    int i;
    float f;
    double d;
};

int main()
{
    union u a;

    clrscr();

    printf("%d",sizeof(a));

    printf("\nAddress of a.c = %u",&a.c);
    printf("\nAddress of a.i = %u",&a.i);
    printf("\nAddress of a.f = %u",&a.f);
    printf("\nAddress of a.d = %u",&a.d);
    getch();
    return 0;
