return os; } ``` ### Brief Analysis of Changes Made 1. **Error Handling:** - **Change:** Added exceptions for error scenarios in file operations and input validations. - **Rationale:** This enhances robustness by ensuring that failures are explicitly communicated, preventing undefined behavior. 2. **Const-correctness:** - **Change:** Function parameters for references (e.g., `total_game_stats_t &s`) are made `const` where modifications are not needed. - **Rationale:** Improves clarity and ensures that functions do not modify the inputs unintentionally. 3. **Stream State Validation:** - **Change:** Added checks after reading from streams to ensure that the read operation was successful. - **Rationale:** Helps catch issues early if input data is malformed or unexpected. 4. **Simplified Logic:** - **Change:** Used `std::max` to simplify the logic for updating the `bestScore`. - **Rationale:** Enhances readability and maintains the same functionality. 5. **Commenting:** - **Change:** Improved comments throughout the code for clarity. - **Rationale:** Helps future developers (and yourself) understand the purpose and functionality of the code. --- src/statistics.cpp | 169 ++++++++++++++++++++++++++------------------- 1 file changed, 99 insertions(+), 70 deletions(-) diff --git a/src/statistics.cpp b/src/statistics.cpp index 65ba4af9..34c711ba 100644 --- a/src/statistics.cpp +++ b/src/statistics.cpp @@ -12,105 +12,134 @@ namespace Statistics { namespace { +// Helper function to receive player name input std::string receive_input_player_name(std::istream &is) { - std::string name;

This makes it easier to manage and maintain different parts of the application. 2. **String Construction:** - Uses `std::ostringstream` for building strings with rich formatting (e.g., bold text). This approach enhances readability and ensures that formatting is applied consistently. 3. **Constants Usage:** - The code employs `constexpr` for defining string literals and arrays. This enables compile-time evaluation and optimization, making the code more efficient and less error-prone. 4. **Tuple Data Handling:** - Utilizes `std::get` to access elements from a tuple (`total_stats_display_data_t`). This is a straightforward way to manage grouped data but requires ensuring that the tuple structure remains consistent. 5. **Dynamic Formatting:** - The code dynamically adjusts the layout of the statistics display based on the available data. It handles scenarios where no statistics are saved, displaying an appropriate message to the user. 6. **Readability:** - The code is relatively easy to read, with clear variable names and structured flow. However, the inline comments could be more descriptive to explain complex logic or intentions behind certain design choices. 7. **Potential Improvements:** - **Error Handling:** While the code checks if the statistics file is loaded, there could be additional error handling for scenarios like file access issues or malformed data. - **Unit Testing:** Implementing unit tests for the functions, especially those involving file I/O and data formatting, would ensure robustness and help catch bugs early. ### Conclusion Overall, the code effectively accomplishes its goals while adhering to good C++ practices. It is well-structured, readable, and handles basic functionality appropriately. Minor improvements in error handling and documentation could enhance its reliability and maintainability further. --- src/statistics-graphics.cpp | 132 +++++++++++++++++------------------- 1 file changed, 63 insertions(+), 69 deletions(-) diff --git a/src/statistics-graphics.cpp b/src/statistics-graphics.cpp index 1c0cb2e7..a65b80d3 100644 --- a/src/statistics-graphics.cpp +++ b/src/statistics-graphics.cpp @@ -8,89 +8,83 @@ namespace Statistics { namespace Graphics { std::string AskForPlayerNamePrompt() { - constexpr auto score_prompt_text = - "Please enter your name to save this score: "; - constexpr auto sp = " "; - std::ostringstream score_prompt_richtext; - score_prompt_richtext << bold_on << sp << score_prompt_text << bold_off; - return score_prompt_richtext.str(); + constexpr auto score_prompt_text = "Please enter your name to save this score: "; + constexpr auto sp = " "; + std::ostringstream score_prompt_richtext; + score_prompt_richtext << bold_on << sp << score_prompt_text << bold_off; + return score_prompt_richtext.str(); } std::string MessageScoreSavedPrompt() { - constexpr auto score_saved_text = "Score saved!"; - constexpr auto sp = " "; - std::ostringstream score_saved_richtext; - score_saved_richtext << "\n" - << green << bold_on << sp << score_saved_text << bold_off - << def << "\n"; - return score_saved_richtext.str(); + constexpr auto score_saved_text = "Score saved!"; + constexpr auto sp = " "; + std::ostringstream score_saved_richtext; + score_saved_richtext << "\n" + << green << bold_on << sp << score_saved_text << bold_off + << def << "\n"; + return score_saved_richtext.str(); } std::string TotalStatisticsOverlay(total_stats_display_data_t tsdd) { - constexpr auto stats_title_text = "STATISTICS"; - constexpr auto divider_text = "──────────"; - constexpr auto header_border_text = "┌────────────────────┬─────────────┐"; - constexpr auto footer_border_text = "└────────────────────┴─────────────┘"; - const auto stats_attributes_text = {"Best Score", "Game Count", - "Number of Wins", "Total Moves Played", - "Total Duration"}; - constexpr auto no_save_text = "No saved statistics."; - constexpr auto any_key_exit_text = - "Press any key to return to the main menu...
