Hello All.
For people who thinks why garbage values get printed , let us look at this ststement
printf("%d >> %d %d >> %d\n", 4 >> 1, 8 >> 1);
We have four %d's, means we should have four variables to print but here we have only two representing first two :ie 4>>1 & 8>>1, last two format specifiers have no variables listed to print , so in such cases, it will print them as garbage values.

4>>1 means divide 4 by 2 power 1 and 8>>1 means divide 8 by 2 power 1 then you will get answer as 2 and 4 if it is less then less then multiply by 2.

@Neetu.
Why we should consider the rest value as garbage I can take it directly as 2 4 why should go for garbage value. Could you please explain me?

@Nizamuddin,
Array always represents starting from '0' position so there is two matrices represented as a a[0] & a[1].
so there is no a[2] so it shows a value as '0'.
If I made any mistake correct me. Thank you.
