WebThere are two bit shift operators in C++: the left shift operator << and the right shift operator >>. These operators cause the bits in the left operand to be shifted left or right by the number of positions specified by the right operand. More information on bitwise math can be obtained in the Wikipedia article on bitwise operations ... WebIn this tutorial, we will learn about bitwise operators in C++ with the help of examples. In C++, bitwise operators perform operations on integer data at the individual bit-level. These operations include testing, setting, or shifting the actual bits. For example, Here is a list of 6 bitwise operators included in C++.

WebSyntax: value << num. Here num specifies the number of position to left-shift the value in value. That is, the << moves all of the bits in the specified value to the left by the number of bit positions specified by num. For each shift left, the high-order bit is shifted out (and ignored/lost), and a zero is brought in on the right.
