Access individual bits in a char c++

You would use the binary operators | (or), & (and) and ^ (xor) to set them. To set the third bit of variable a, you would type, for instance: 

a = a | 0x4

// c++ 14
a = a | 0b0100

Note that 4’s binary representation is 0100

If you want access bit N:

Get: (INPUT >> N) & 1;

Set: INPUT |= 1 << N;

Unset: INPUT &= ~(1 << N);

Toggle: INPUT ^= 1 << N;
