C ++到Java代码的转换

Question

I have in C++

r.bits[k] &= 0xFF ^ msk;

So in Java

r.bits[k] = r.bits[k] & 0xFF,

but what is the meaning of the caret symbol? msk also will contain hexadecimal values. I know the caret symbol is a type of pointer in C++ but not sure what it is doing here. Please explain.

Answer 1

The ^ symbol represents the bitwise XOR operator in C, C++. List of operators in C, C++ .

The same operator is available for Java as well. XOR Operator in Java .

Answer 2

The caret means bitwise XOR

The caret does NOT mean a kind of pointer in C++ (though MSVC++ has extension for C++/CLI that use that symbol)

Answer 3

Caret symbol in C++ means XOR logical operation. Meaning for the code 0xFF ^ msk; is that you take bits in msk and invert them (zeroes to ones and vice versa)

Answer 4

Answer 5

The ^ is bitwise XOR.

For example:

1 ^ 1 = 0
2 ^ 1 = 3
0 ^ 1 = 1

If you are using C++/CLI then it is also a kind of reference (handle).
