Program Plan Intro

Logical “&&” Operator:

Logical operator combines the results of one or more conditions.

  • The logical “&&” is used to evaluate two expressions in order to obtain a single relational result.
  • It returns the Boolean value “True” when both the operands are true, otherwise returns “False”.
  • The first operand is evaluated first and all the side effects are completed before evaluating the logical “and” expression.
  • The second operand is evaluated only if the first operand is “True”.

Syntax for “&&” operator:

The syntax for “&&” operator is given below:

expression1 && expression2

Logical “||” Operator:

Logical operator combines the results of one or more conditions.

  • The logical “||” is used to evaluate two expressions in order to obtain a single relational result.
  • It returns the Boolean value “True” when one of the operands is “True”. It returns “False” only if both the operands are “False”.
  • The first operand is evaluated and all the effects are completed before it continues to evaluate the logical “||” expression.
  • The second operand is evaluated only if the first operands return “False”.

Syntax for “||” operator:

The syntax for “||” operator is given below:

Expression1 || expression2

Logical “!” Operator:

Logical NOT operator one conditions.

  • The logical “!” is used to evaluate one expressions in order to obtain a single relational result.
  • It returns the Boolean value “True”. If the operand is “False”.
  • It returns the Boolean value “False”. If the operand is “True”.

Syntax for “!” operator:

The syntax for “!” operator is given below:

!Expression2
