CSIT 345 Lab 2 Process Programming Your lab requirement is to write program codes for 3.21 and shared memory program for producer and consumer as shown in the following. You can start with the code provided in the virtual machine in the virtual box you installed. The code can be found in /home/oscreader/osc9e-src/ch3 a. For 3.21, you can start with the newprocposix.c and modify the code to meet your requirement. Then type: gcc neypCOCROSİS.c to...

This lab, for which you may work in groups of two, will require you to use a C structure to hold a record of any kind of data, i.e., address book, library of books as with chapter 14, etc. These records will be held in dynamic memory using memory allocation (malloc) to create new memory and the function (free) to release memory created via (malloc). Do not use linked lists for this assignment, we are using dynamic memory allocation to...

Creating linked list data structure Overview The purpose of this assignment is for you to write a data structure called a Linked List, which utilizes templates (similar to Java’s generics), in order to store any type of data. In addition, the nature of a Linked List will give you some experience dealing with non-contiguous memory organization. This will also give you more experience using pointers and memory management. Pointers, memory allocation, and understand how data is stored in memory will...

10) Unlike a signal, which conveys only the occurrence of a particular event and contains no information content, a pipe can be thought of as a scratch file created by a system call. It can be used as a communications channel between concurrently running processes. The interface call to a pipe is similar to that for any file. In fact, the process reads and writes to a pipe just like any file. Unlike files, however, pipes do not represent actual...

Exercise #1: Write a C program that contains the following steps (make sure all variables are int). Read carefully each step as they are not only programming steps but also learning topics that explain how functions in C really work. Ask the user for a number between 10 and 99. Write an input validation loop to make sure it is within the prescribed range and ask again if not. Commenting out the existing coding, write the code to divide a...
