Cincinnati Software, which currently specializes in the installation of manufacturing resource planning (MRP II) systems in small firms, is planning a major expansion into installing the new enterprise resource planning (ERP) systems. This major expansion into the hottest software area will be organized as an in-house project of strategic importance. The company has selected a project manager and team to follow the project through to completion. The project team is very interested in selecting an appropriate scheduling technique for the project. The project manager has thus set the following guidelines for the selection process: simple; able to show duration of events, the flow of work, and the relative sequence of events; able to indicate planning and actual flow, which items may proceed at the same time, and how far they are from completion. The assistant project manager favors the Gantt chart, the finance representative likes PERT, and the information technology department head prefers CPM. If you were the project manager, which method would you use, and why?

This question involves a class named textfile that represents a text file. public class textfile { private string filename; private string filename; private arraylist words; // constructors not shown // postcondition: returns the number of bytes in this file public int filesize() { } // precondition: 0 < = index < words.size() // postcondition: removes numwords words from the words arraylist beginning at // index. public void deletewords(int index, int numwords) { } // precondition: 0 < = index < = words.size() // postcondition: adds elements from newwords array to words arraylist beginning // at index. pub lic voidaddwords(int index, string[] newwords) { } // other methods not shown } complete the filesize() method. the filesize() is computed in bytes. in a text file, each character in each word counts as one byte. in addition, there is a space in between each word in the words arraylist, and each of those spaces also counts as one byte. for example, suppose the words arraylist stores the following words: { mary had a little lamb; its fleece was white as snow. } the filesize() method would compute 4 + 3 + 1 + 6 + 5 + 4 + 6 + 3 + 5 + 2 + 5 as the sum of the lengths of each string in the arraylist. the value returned would be this sum plus 10, because there would also be 10 spaces in between the 11 words. complete the filesize() method below: // postcondition: returns the number of bytes in this file public int filesize() { }
