Guess the output in C without checking?😊😊😊☺️☺️

Question

#include <stdio.h>
union DATA{
int one;
int two;
};
void main() {
union DATA t;
t.one=3;
t.two=5;
printf("%d\n",t.one);
}

Answer 1

I didn't know about this union type, so I googled about it. I used to think I would give 3, but now I know it will give 5 because of this little word.

I liked the challenge, I don't know if there is a lesson about UNION on the site, but if it doesn't, you should do one! : D
