I have a project to write and I need a grade 5 100%. You should write a program implementing the calculator's functionality. Interface appearance: [login to view URL] simple calculator functionality(grade 3):•the screen appearance should reflect the numeric keypad(see included file),•put the result of action on top,•performing subsequent mathematical operations: after pressing enter (=) the result of the operation is printed, pressing the operation sign performs the operation with the previous result of the operation, while pressing the number starts a new mathematical operation (deleting the result), •performing subsequent actions (e.g.: 2 + 2 * 2) results in performing these actions in the order they were entered (result 8),•the num button takes over the functionality of the power„^”. [login to view URL] calculator functionality(grade 4):•use graphic buttons (this may be the simplest graphic with a color change),•the result of the operation can be presented in the form of binary, octal hexadecimal (additional buttons), •enter the history button: opening a new window with information about theactions taken since the application was started, showing the actions in the following lines of the list. [login to view URL] with logic(grade 5):•performing subsequent mathematical operations: the calculator gets values and mathematical operations, calculates the result after pressing = (eg: 2 + 2 * 2 = 6), no limit on the number of operating parameters( np..:[login to view URL]),•the graphic layout of the buttons should be independent of the device size (phone / tablet): the buttons should fill the entire screen content horizontally, while scaling the screen the buttons should keep their proportions.
