In Array of union last member doesn't over write when trying to print but in union it does why?

Question

#include <stdio.h>

union type {
int i_val;
float f_val;
char ch_val;
};

int main() {
union type arr[3];
arr[0].i_val = 42;
arr[1].f_val = 3.14;
arr[2].ch_val = 'x';
printf("1st element is %d, 2nd is %f, and the 3rd is %c", arr[0].i_val, arr[1].f_val, arr[2].ch_val);

return 0;
}

Answer 1

This is because sharing of memory happens in union, not in array. When you define an array of union then it is just simmilar to defining multiple union variables.
