#111 – Combining the Logical or Shift Operators with the Assignment Operator
October 6, 2010 Leave a comment
To perform a logical bitwise operation on a variable and assign the result back to the original variable, you can use the following shortcut.
Instead of writing :
x = x & 0x0020;
You can write :
x &= 0x0020;
You can do the same thing with the other bitwise logical operators and the shift operators:
x |= 0x2200; // Logical OR x ^= 0x1A1A; // Logical XOR x <<= 4; // Left-shift x by 4 bits x >>= 3; // Right-shift x by 3 bits
