Controlled NOT $($CNOT$)$ is a reversible gate which flips the target bit $($T$)$ if

the control bit $(C)$ is equal one and leave the target bit unaltered, if the

control bit $(C)$ is equal zero. Give the truth table for this circuit. There are

two inputs $(C,T)$ and two outputs $(C^{\text{'}},T^{\text{'}}).$
