1. What is the difference between a Java compiler and a Java interpreter? 2. Write a user-defined class called Person. This class should have private instance variables defined as: private int age;private String firstName;private String lastName; In addition, the class should have a constructor defined as: public Person(String _firstName, String _lastName, int _age) that assigns values to the private instance variables. The class should also include the following public methods: public void printName() – prints the person's namepublic void printAge() – prints the person's agepublic void printAgeGroup() – prints the person’s age group (i.e. 20's. 30's, etc.) Only include this... click for more

C++ program that uses an array

Write a program that reads a file consisting of students test scores in the range of 0-200. It should then determine the number of students having scores in each of the following ranges: 0-24, 25-49, 50-74, 75-99, 100-124, 125-149, 150-174, and 175-200. Output the score ranges and the number of students. (Run your program with the following input data: 76, 89, 150, 135, 200, 76, 12, 100, 150, 28, 178, 189, 167, 200, 175, 150, 87, 99, 129, 149, 176, 200, 87, 35, 157, 189.)

For this question, describe the concept of a signal, and indicate how the parent application can be configured to act upon the SIG_CHILD signal from each child as they terminate to avoid the zombie issue.

When a child process is fork()ed, a parent may wait for the successful completion of the child via the wait() service (or one of its variants) so that the return result of that application can be read from the process descriptor block. If the parent does not perform a wait() operation on the child process after it terminates, Unix will keep the process descriptor block active for this application in hopes that eventually the parent will wait() or that the parent will itself terminate. If you perform the ps command in this scenario, you may find a number of "zombie" processes - these are processes marked with a Z in the output of ps that are children of a currently running parent that h... click for more
