Answer / neha tibrewal ritm jaipur
firstly value of a is printed. value of a=5, so 5 is printed.
Now, a<<2 means 5<<2 i.e 5 is left shifted by 2.
in binary 5= 101
101<<2= 10100 and decimal value of 10100=20.
so, a<<2=20.
again, a>>2 means 5>>2 i.e 5 is right shifted by 2.
101>>2= 001 and decimal value of 1=1.
so, a>>2=1.

Answer / sathish
go through right shift & left shift operator function.
Ex: a<<2 = 5<<2 = 00000101(in binary)<<2 = 00010100(in
binary) = 20(in decimal)

int main()
{
int a=5;
printf("%d,%d,%d\n",a,a<<2,a>>2);
getch();
return 0;
}
the ans is 5,20,1
How this ans is :
(1) a=5
(2) a=5

Answer / saikumar
main()
{
int a=5;
printf("%d,%d,%d\n",a,a<<5,a>>2);
}
explanation:in the above program already we assinged a value is 5.
in the printf statement a is 5
and a<<2 it means 'a' leftshift 2 it should converted in to binary form .first we take 5 is in the binary form is 101.
and next we take 2 is in the binary form 010.
we have to shift the 5 to left side of 2 terms .
101<<010=10100=20.
101>>010=001=1.
output:
5
20
1
