Worksheet I
Algorithm Verification
Examine the following test score program that contains a multiple-alternative selection control structure:
Main Module
Declare X As Integer
Write “Enter an Integer test score from 0 to 100”
Input X
If (X >= 0 AND X < 49) Then
Write "You fail" Else
If (X >= 50 AND X < 70) Then
Write "Your grade is " + X
Write "You did OK" Else
If (X >= 70 AND X < 85) Then
Write "Your grade is " + X
Write "You did well" Else
If (X >= 85 AND X < 100) Then
Write "Your grade is " + X
Write "You did great" End If
End If
End If
End If
Write "How did you do?"
End Program
