booelan v = (true || !(!false)) ? false : true = (true || !true) ? false : true = (true || false) ? false : true = true ? false : true = false The parameter of the if statement has the value false so it will not execute and control is transferred to else clause. Since value of v is false, (v == true) returns false and v = false. The parameter of an if statement is an expression that returns a boolean value. So if(0 == 0) and if(true) mean the same thing as the expression (0 == 0) returns true.
