Description
When the or operator has operands of boolean type then it performs boolean OR. The result of the operation is of boolean type and is equal to true if either operand is true, and false if both operands are false. By default short-circuit evaluation is used when performing the boolean OR (i.e. The left operand is evaluated first and if it is true then the right operand is not evaluated because the result of the operation must be true). A compiler option can be used to enable/disable short-circuit evaluation.
Example
false or false results in false
false or true results in true
true or false results in true
true or true results in true
