Boolean+type

Boolean is a variable type with two posible values: true, and false. The default value of a boolean is flase. Make a new boolean: > boolean x = false; Modify a boolean: > x = !x; //set x to false if x is true before the statement is called// example: > if( true) is equivalent to if( ture == ture) always true ; > if( !true) is equivalent to if( false == true) //always false;
