what is xor_eq c++
Explanation of xor_eq
in C++
In C++, xor_eq
is a compound assignment operator that performs a bitwise exclusive OR (XOR) operation between two operands and assigns the result to the left operand. It is equivalent to the expression a ^= b
, where a
and b
are variables or expressions.
The xor_eq
operator combines the XOR operation with assignment, allowing you to modify the value of a variable by XORing it with another value and storing the result back into the same variable.
Here's an example to illustrate the usage of xor_eq
:
int a = 5;
int b = 3;
a xor_eq b; // Equivalent to: a ^= b;
In this example, the value of a
is XORed with the value of b
, and the result is stored back into a
. After the operation, the value of a
will be 6
because 5 XOR 3
is 6
.
It's important to note that xor_eq
is a bitwise operator, meaning it operates on the individual bits of the operands. It performs the XOR operation on corresponding bits of the operands, resulting in a new value with the bits set where the corresponding bits of the operands differ.
The xor_eq
operator can be useful in various scenarios, such as flipping specific bits in a binary representation or implementing certain algorithms that rely on bitwise operations.
