Logical operator: Logical operators are used to validate an expression and return the Boolean values as “true” or “false”. Some of the logical operators are as follows: Logical “and” operator Logical “or” operator The “not” operator Logical “and” Operator: Logical operator combines the results of one or more conditions. The logical “and” 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 it 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 “and” operator: The syntax for “and” operator is given below: expression1 and expression2 Logical “or” Operator: Logical operator combines the results of one or more conditions. The logical “or” 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 “or” expression. The second operand is evaluated only if the first operands return “false”. Syntax for “or” operator: The syntax for “or” operator is given below: expression1 or expression2 Logical “not” Operator: The logical “not” operator is the unary operator that takes an operand and reverse its logical value. Syntax for “not” operator: !expression1

Program Plan Intro

Logical operator:

Logical operators are used to validate an expression and return the Boolean values as “true” or “false”. Some of the logical operators are as follows:

Logical “and” operator

Logical “or” operator

The “not” operator

Logical “and” Operator:

Logical operator combines the results of one or more conditions.

The logical “and” 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 it 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 “and” operator:

The syntax for “and” operator is given below:

expression1 and expression2

Logical “or” Operator:

Logical operator combines the results of one or more conditions.

The logical “or” 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 “or” expression.

The second operand is evaluated only if the first operands return “false”.

Syntax for “or” operator:

The syntax for “or” operator is given below:

expression1 or expression2

Logical “not” Operator:

The logical “not” operator is the unary operator that takes an operand and reverse its logical value.

Syntax for “not” operator:

!expression1

A. Modified TRUE of FALSE. Write T if the statement is TRUE and CHANGE the underlineword if the statement is FALSE._______________2. There is only one way to determine whether a business is going to be profitable or not.

Step 1: Consider the following values set to variables. myAge = 32 yourAge = 18 myNumber = 81 yourNumber = 17 votingAge = 18 myName = “Katie” yourName = “Bob” Based on the values to the variables in Step 1, do the following conditions result in a true or false statement? (Reference: Boolean Expressions, page 119). The condition True or False myAge >= yourAge yourAge > myAge myAge == 45 yourAge == votingAge votingAge <= yourAge myAge <= votingAge myName != yourName myNumber <= myAge yourNumber >= myAge yourNumber != 17
