charset=UTF-8 Content-Transfer-Encoding: 8bit - Add Boolean to bool type transformation - Add int.Parse() to std::stoi() transformation - Add Console.ReadLine() to std::getline() transformation - Add Console.WriteLine() to std::cout transformation for variables - Add using System; to #include and #include transformation - Add comprehensive test cases for Boolean type and I/O transformations - Update existing HelloWorld test to expect proper includes These improvements significantly enhance the translation quality for common C# constructs, addressing the issues raised in GitHub issue #16. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- .../CSharpToCppTransformerTests.cs | 63 ++++++++++++++++++- .../CSharpToCppTransformer.cs | 20 +++++- 2 files changed, 81 insertions(+), 2 deletions(-) diff --git a/csharp/Platform.RegularExpressions.Transformer.CSharpToCpp.Tests/CSharpToCppTransformerTests.cs b/csharp/Platform.RegularExpressions.Transformer.CSharpToCpp.Tests/CSharpToCppTransformerTests.cs index edca381..88165b8 100644 --- a/csharp/Platform.RegularExpressions.Transformer.CSharpToCpp.Tests/CSharpToCppTransformerTests.cs +++ b/csharp/Platform.RegularExpressions.Transformer.CSharpToCpp.Tests/CSharpToCppTransformerTests.cs @@ -24,7 +24,10 @@ public static void Main(string[] args) Console.WriteLine(""Hello, world!"");
