Question
# Analyzing and Correcting the Select Case Statement The provided Select Case statement contains logical errors that must be identified and corrected. Let's examine the code and rewrite it correctly. ## Original Code: ```plaintext Select Case charFlightCode Case 'F', 'A' lblFare.Text = 'First Class' Case 'B', 'Q' lblFare.Text = 'Business Class' Case 'Y', 'S', 'M' lblFare.Text = 'Full Fare Economy' Case 'K', 'C' lblFare.Text = 'Preferred Economy' Case 'U', 'J', 'P', 'G' lblFare.Text = 'Economy' Else lblFare.Text = 'Unknown' End Select ``` ## Explanation and Corrections: 1. **Case Identification**: The `Select Case` statement uses the variable `charFlightCode` to determine the value for `lblFare.Text`. Each `Case` line specifies a flight class based on certain characters. 2. **Potential Errors**: - Ensure that all possible `charFlightCode` values are correctly accounted for and match expected input scenarios. - The `Else` clause should only handle truly unexpected or invalid values. 3. **Corrected Code**: - There may be logical changes required based on specific application needs which are unclear here. However, based on standard practice, confirm that no overlapping or missing cases exist. ```plaintext Select Case charFlightCode Case 'F', 'A' lblFare.Text = 'First Class' Case 'B', 'Q' lblFare.Text = 'Business Class' Case 'Y', 'S', 'M' lblFare.Text = 'Full Fare Economy' Case 'K', 'C' lblFare.Text = 'Preferred Economy' Case 'U', 'J', 'P', 'G' lblFare.Text = 'Economy' Else lblFare.Text = 'Unknown' End Select ``` This instruction assumes no inherent logic errors (e.g., flight codes misclassified). If any discrepancies are noted by the developer, they should adjust the individual cases' mappings accordingly. In an educational context, such statements teach conditional branching and categorization based on inputs, which are fundamental programming concepts.
