int a2 [ ] = {23, 56, 28, 29};
int a3 [ ] = {-12, 27, -31};
int x [ ] = {a1, a2, a3};
void print ( int &a[ ] )
{
printf("%d", a[0][2]);
printf("%d", a[2]);
printf("%d", ++a[0]);
printf("%d", (++a)[0]);
printf("%d\n", a[-1][+1]);
}
main( )
{
print(x);
}

Solution

The correct option is B 8, -12, 7, 23, 8

a[ ] = &x;
a[ ] contain base address of array x;

1. Printf (a[0] (2}) =((a +0) +2)
= (100 +2 $\times$ 4)
= (108)
= 8

2. Printf (a[2]) = ((a + 2) + 0)
= (408 + 0)
= (408)
= -12
3. Printf (++ a[0]) = (++(a + 0))
= (++(100))
= (104)
= 7

4. Printf ((++ a)[0]) = ((a + 1) + 0)
= ((404) + 0)
= (200 + 0)
= (200)
= 23

5. Printf (a[-1] [+1]) = ((a — 1) + 1)
= ((404-4) +1)
= (104+1)
= (104 + 1 $\times$ 4)
= *(108)
= 8

Note: In step 3 ‘a1’ point to ‘a1’ = 104 and in step 4 ‘a’ point to 404 as starting address used
