In this exercise, you’ll add code to an inventory maintenance application that reads data from and writes data to an xml file. 1. open the inventorymaintenance with xml file directory, and display the code for the invitemdb class. 2. add code to the getitems method that creates an xmlreadersettings object that ignores white space and comments. then, create an xmlreader object for the inventoryitems. xml file that’s included in the project and that uses the reader settings. (the path constant contains the path to the xml file.) 3. add code that reads each item element, stores the contents of the child elements in an invitem object, and adds the object to the list object. be sure to check that the file contains at least one item element before the loop that processes these elements is executed. then, close the xmlreader object. 4. add code to the saveitems method that creates an xmlwritersettings object that indents each element four spaces. then, create an xmlwriter object for the inventoryitems. xml file that uses the writer settings. 5. add code that writes an xml declaration line and a start tag for the items element. then, add code that creates an item element for each invitem object in the list object. each property of the invitem object should be saved as a child element with the same name as the property. 6. add code that writes the end tag for the items element and then closes the xmlwriter object. 7. test the application to be sure it works correctly.

How do i get the most points, without any effort?

For this assignment you have to write a c program that will take an infix expression as input and display the postfix expression of the input. after converting to the postfix expression, the program should evaluate the expression from the postfix and display the result. what should you submit? write all the code in a single file and upload the .c file. compliance with rules: ucf golden rules apply towards this assignment and submission. assignment rules mentioned in syllabus, are also applied in this submission. the ta and instructor can call any students for explaining any part of the code in order to better assess your authorship and for further clarification if needed. problem: we as humans write math expression in infix notation, e.g. 5 + 2 (the operators are written in-between the operands). in computer's language, however, it is preferred to have the operators on the right side of the operands, ie. 5 2 +. for more complex expressions that include parenthesis and multiple operators, a compiler has to convert the expression into postfix first and then evaluate the resulting postfix write a program that takes an "infix" expression as input, uses stacks to convert it into postfix expression, and finally evaluates it. it must support the following operations: + - / * ^ % ( example infix expression: (7-3)/(2+2) postfix expression: 7 3 2 2 result: rubric: 1) if code does not compile in eustis server: 0. 2) checking the balance of the parenthesis: 2 points 3) incorrect postfix expression per test case: -2 points 4) correct postfix but incorrect evaluation per test case: -i points 5) handling single digit inputs: maximum 11 points 6) handling two-digit inputs: 100 percent (if pass all test cases)
