Calculator with Csharp

With C# programming Design a calculator similar to the Standard Basic Windows Calculator. Your calculator should perform the operations shown in the screen capture below. The main menu bar should have the EDIT (contains Copy and Paste) and HELP (contains About) menu strip items. You should design the event handlers to handle the Click event for Edit/Copy, Edit/Paste and Help/About menu strip items. When the About menu strip item is selected a new form will be shown to display a brief manual how to use your calculator. Please note that your calculator should prevent run-time errors such as a division by 0, a square root of a negative number, multiple decimal points, etc. It is required to follow naming conventions when naming your controls
