FOR HELP BUTTON YOU CAN GET IMAGE OF HELP OPTION ON WINDOW CALCULATOR. DONT NEED TO CREAT "HELP" PROGRAM.

Disable Dword, Word, Byte, but keep the buttons there. Also, no interaction of the mouse on the binary bits area is required. Just display 64 bits for all the items with appropriate bits filled in based on the value in the number field.

Test Case: Please find below the list of test cases. 1.Look and feel of the calculator. 2.The 64 bits binary value of the entered number in the number field should be displayed correctly. 3.Should be able to access some help documentation from the menu item Help. Does not have to be the same as the Windows Calculator 4.Should be able to hide and show the calculator using the menu item View. 5.Should be able to copy the content (in the number field) using the menu item Edit. 6.All basic arithmetic operations (+, - , / , *, etc.) must be performed correctly. Results with decimal places or negative values should be displayed appropriately. 7.There is no order of operation expected; if someone has implemented it that way then it is OK either way 8.There should be no interaction of the mouse expected on the binary bits area. 9.Functionality of C, CE and Backspace should be the same as that of windows calculator.
