main() { int a=4,b=2; a=b<<a + b>>2; printf("%d", a); }..

Answer / neha saxena

a=b<<a+b>>2
=2<<4+2>>2

According to precedence Table
1) + operated very 1st, (4+2=6)
2) then<< (left shift), (2<<6, 2 shifted left side 6 times
= 128)
3) and at last >> (right shift), (128>>2, 128 shifted right
side 2 times = 32)

Answer / satya

yes , the output will be 32....
<< and >> are bitwise operators... not relational ops..
reason:
<< means left shift operator..
>> means right shift operator..
for example.. if we give 2>>1
binary number for 2 is 0000 0010
the operator is right shift..so 0000 0001
for example.. if we give 2<<1
binary number for 2 is 0000 0010
the operator is left shift..so 0000 0100
go through this u will get the output...

Answer / manish soni tagore collage jai

b<<a=2<<4=32;
and
b>>2=1>>2=0
so
32+0=32

Answer / alamuru sreenivasa reddy

2<<4 that means 2 is left shifted by 4 times. then we will get 0010 0000=32 in decimal form. similarly 1>>2 means that is right shifted 2 times we will get 0000 0000=0.. so 0+32=32

Answer / vignya

size of integer is 8 bits
a=0000 0100, b=0000 0010;
b>>2 becomes 0000 0000 and b<<a becomes 0010 0000
on whole a= 0010 0000+ 0000 0000=0010 0000 =32

Answer / sandeep kumar

Both shift operator has same precedence but associativity left to right so first calculate b>>2=0 then calculate b<<4=32 then add the both result

Answer / aravind

It shows syntax error because relational operators are used only for checking conditions.
