What is the output of the following program, where the zu format specifier in the printf statement below displays the result of sizeof as a decimal integer?

#include
#include

typedef union {
double d;
char c[20];
}u;

int main() {
u temp;
temp. d = 11.5;
strcpy(temp. c, "cs 354");
printf("%zu, %f, %s\n",sizeof(temp), temp. d, temp. c);
return 0;
}
20, garbage value, cs 354
20, 11.5, cs 354
28, 11.5, cs 354
28, garbage value, cs 354
runtime error
