Question

Module main()

    // Local variables

    Declare Real lengthA, widthA, areaA

    Declare Real lengthB, widthB, areaB

 

    // Get the dimensions of rectangle A.

    Display "Enter the dimensions of Rectangle A."

    Call getRectangle(lengthA, widthA)

 

    // Get the dimensions of rectangle B.

    Display "Enter the dimensions of Rectangle B."

    Call getRectangle(lengthB, widthB)

 

    // Calculate the rectangle areas.

    Set areaA = lengthA * widthA

    Set areaB = lengthB * widthB

 

    // Compare the areas.

    If areaA > areaB Then

        Display "Rectangle A has the greater area."

    Else

    If areaB > areaA Then

       Display "Rectangle B has the greater area."

    Else

       Display "Both rectangles have the same area."

    End If

    End If

End Module

 

// The getRectangle module gets a rectangle's length and width from

// the user and stores the input in the reference parameters length

// and width.

 

Module getRectangle(Real Ref length, Real Ref width)

    Display "Length:"

    Input length

    Display "Width:"

    Input width

End Module

I want flow-chart and pseudocode for this please.
