Increment and decrement operatorsIncrement and decrement operators ++++ increases variable value by 1increases variable value by 1 ---- decreases variable value by 1decreases variable value by 1 SyntaxSyntax a++; //increase ‘a’ by 1//increase ‘a’ by 1 a--; //decrease ‘a’ by 1//decrease ‘a’ by 1 C OperatorsC Operators
- 8. Logical operatorsLogical operators Logical operators are used to combineLogical operators are used to combine two or more relations. The logicaltwo or more relations. The logical operators are called Boolean operatorsoperators are called Boolean operators because the tests between values arebecause the tests between values are reduced to either true or false.reduced to either true or false.
