Chapter 4.3, Problem 4.5CP

Program Plan Intro

“If…Then...Else” statement:

• The “If…Then...Else” statement is used to run the particular block of statements, based on the value of the condition.
• The “If” statement can be followed by an “Else” statement that executes when the Boolean expression is “false”.

Syntax:

Consider the syntax for the “If...Then...Else” statement is as follows:

If condition Then   

  'statement

Else    

    'statement

End If

Here, if the “condition” is a Boolean condition is “true”, then it executes the “If” block other it executes “Else” block.

Explanation of Solution

2.

Given statement:

'assign the value to the variable

intX = 100

'check "intX" value is less than or equal to 1

If intX <= 1 Then

    'assign the value to the variable

    intY = 99

'else statement

Else

    'assign the value to the variable

    intY = 0

'end the statement

EndIf

Explanation:

• Here, the “intX” variable is assigned with the value “100”.
• Check the value of “intX” is less than or equal to “1” or not...

Explanation of Solution

3.

Given statement:

'assign the value to the variable

intX = 0

'check "intX" value is not equal to 1

If intX <> 1 Then

    'assign the value to the variable

    intY = 99

'else statement

Else

    'assign the value to the variable

    intY = 0

'end the statement

EndIf

Explanation:

• Here, the “intX” variable is assigned with the value “0”.
• Check the value of “intX” is not equal “1” or not.
  • If the condition is “true”, assign the value “99” to the variable “intY”...
