Question: 1
Assume that ints and floats are 32-bit wide.
What happens if you try to compile and run this program?
#include <stdio.h>
union uni {
float f, g;
int i, j;
};
int main (int argc, char *argv[]) {
union uni u;
printf ("%ld", sizeof (u) ) ;
return 0;
}
Choose the right answer:
A. The program outputs 16
B. The program outputs 8
C. Compilation fails
D. The program outputs 4
E. The program outputs 24
Answer: D
Explanation:
This is because when you initialize u with some values, only one member of u will be as-signed a
value at a time, and the rest will remain uninitialized. Therefore, when you print sizeof(u), it will
show the size of the largest member, which is f in this case. Since f is 4 bytes long, sizeof(u) will
be 4 bytes as well.
