"|" this operator is known as OR operator
and
we know that with or operator
1| 0 = 1
1| 1 = 1
that's why here we use or operator |

Why you did't think like this?
1& 0=0.
1& 1=1. |

Anji here you take input as 1 & we want output 1 i.e. on.
But when our input is 0 & we want output as 1 I. E. On.
At that time if we & with 1 or & with 0 output will be always 0.
That's why we hav 2 use | to on the bit. |

@Rupa:.
If input is 0, you have to use 1 i.e. 0|1=1. |

Best use of the & operator is to check whether a particular bit od an operand is ON or OFF.
Why, we are not using &. ? |

| If | is OR operator than what do we call || operator as? |

Logical OR ||
Ex: if(a || b) { ... }
Bitwise OR |
Ex: result = a | b; |

| || it will call as logical OR.here OR truth table is true false=true, true true=true.so here OR operator is on a particular bit in a number. |
