Bit OR

1 = 0000 0001
2 = 0000 0010
1|2 = 0000 0011

OR Table

A B A|B
0 1  1
0 0  0
1 0  1
1 1  1

Use Case

BitWise OR is used to set the perticular bit.

Example : Suppose we have to set bit 2 in 0000 0001

0000 0001 | 0000 0100 = 0000 0101

It is bitwise OR operator which does digital ORing between 2 values like 1 has binary value 0001 and 2 has binary value 0010, so if you write 1 | 2 then it will return 0011 value which is 3.

For bool, it does boolean OR, i.e. gives false only if both the operands are false.

It is defined for bool and integral types. It can also be overloaded for user defined types. Have a look here at msdn.

Since the integer question is answered already:

For bool values, like bool x = true | false x is true.

It is false, if both operants are false, and only BOTH. Everything else returns true

 true | false  => true
false | true => true
 true | true => true

false | false => false
