To change a specific bit to 0/1 in C/C++

Use the bitwise OR operator (|). number |= << x; sets the x-th bit to 1.

Use the bitwise AND operator (&). number &= ~(1<<x); sets the x-th bit to zero

Use the XOR operator (^{). number ^= 1 << x; replaces the x-th bit with 0 if it is 1, and changes to 1 if it is 0.}

Use the bitwise AND operator (&). (number >> x ) & 1; returns 1 if the x-th bit is 1, and 0 if 0 is 0.
