What is << operation in c++????

Question

Explain shiftwise

Answer 1

Sachin Shah I think you are asking about left shift and right shift operators. So consider this example-

int a = 8; // Now write it's binary representation which is-
00001000 --> This is 8.

a>>1 shifts every digit to right by 1 place. So it becomes-
00000100 --> This is 4.

a<<1 shifts every digit to left by 1 place. So it becomes-
00010000 --> This is 16.

Answer 2

• Multiply by a power of 2
x = x << 1; // x = x * 2
x = x << 6; // x = x * 64

• Divide by a power of 2
x = x >> 1; // x = x / 2
x = x >> 3; // x = x / 8

Sachin Shah

This question is missing things. Such as a explicate description. Which makes it challenging to answer.
