Code:

#include <stdio.h>

union example
{
    int x;
    char y;
    float z;
};


int main()
{  
    union example v;


    v.x = 2;
    v.y ='A';
    v.z = 13.43;
    printf("v.x = %d \n", sizeof(v.x));
    printf("v.y = %d \n", sizeof (v.y));
    printf("v.z = %d \n", sizeof(v.z));
    printf("v = %d \n", sizeof(v));


    return 0;
    
    }

Output
v.x = 4
v.y = 1
v.z = 4
v = 4
