because here 1<<1 act as left shift operator.. 1<<1 value is 2 and 2 print by cout..

<< is bitwise left shift operator The left-shift operator causes the bit pattern in the first operand to be shifted to the left by the number of bits specified by the second operand. So 1 << 1 = `0000 0010` evaluates to 2
