Structure in c

Question

The output is 11, could you explain why?
#include <stdio.h>
struct xyz{
int a;
};
int main() {
struct xyz obj1={1};
struct xyz obj2=obj1;
printf("%d", obj2.a);
obj2.a=100;
printf("%d", obj1.a );
return 0;
}

Answer 1

obj1={1};
//the a int for obj1 is 1 so a=1
//Then
obj2=obj1;
//obj2 is also 1
printf("%d",obj2.a);
//print 1
.......
printf("%d",obj1.a);
/*print 1
so the global output is 11
if you add "\n" to the first print statement you get an output of:
1
1 /*
