Task 1 Create a simple calculator for 4 arithmetic operations for real numbers. ??????????? X 2 Y 3 Z 6 + - * / X Recommendations: 1. Create a project Wind ows Forms in MS Visual Studio; 2. When entering fractional numbers, use the fractional separator depending on the Windows regional settings (semicolon); 3. Use the try statement to handle exceptions (incorrect data entry); 4. Processing of Click events for operation buttons is as follows (example for the + button) private: System: Void button1_Click (System: Object ^ sender, System:: EventArgs ^ e) { try { textBox3-> Text = (Convert::ToDouble (textBox1-> Text) + Convert::ToDouble (textBox2-> Text)). ToString (); } catch (...) { textBox3-> Text = "Error"; } } 5. Perform the remaining operations in the same way, replacing + with -, *, /.
