A bit can be cleared using the bitwise AND operator (&
).
// Bit x will be cleared
number &= ~(1LL << x);
reset(x)
or set(x,false)
- clears the bit at position x
.
std::bitset<5> num(std::string("01100"));
num.reset(2); // num is now 01000
num.reset(0); // num is still 01000
num.set(3,false); // num is now 00000
