c++: How to flip the binary values of each bit in int
bit, c++, int
Solution
You're looking for the binary not operator (~).
So
int a = 0x04;
int b = ~a;
the value of `b` is 1111 1111 1111 1011 while the value of `a` is 0000 0000 0000 0100.
The wikipedia and the GNU C have plenty of information of these binary operators.
Problem
Suppose I have an integer `int a` In c++, as this `int` uses 4 bytes(32 bits) of memory, all bits would be occupied by either `1`'s or `0`'s. So, I wish to flip the values of each bit. That is, wherever in each bit there is `1` convert it to `0` and `0` to `1`. Is there an easy way to go about this? Edit: I also want to play with boolean algebra also. That is if I can execute basic boolean operations like addition, subtraction, etc.
