i have an example of this input
$customer = new Customer();
$customer->include_related('desease', array('desease_name'),
true, true);
$customers = $customer->get();
foreach($customers as $c){
echo $c->firstname . $c->lastname;
echo "<br>";
foreach($c->desease as $cd)
{
echo $cd->desease_name;
echo "<br>";
}

A. File I/O using C library functions File I/O in C is achieved using a file pointer to access or modify files. Processing files in C is a four-step process: o Declare a file pointer. o Open the desired file using the pointer. o Read from or write to the file and finally, o Close the file. FILE is a structure defined in <stdio.h>. Files can be opened using the fopen() function. This function takes two arguments, the filename and...
Write a program in C using Unix system calls and functions that will change the permissions on a file. The executable shall be called “mychmod” and will be executed by: mychmod -u rwx -g rwx -o rwx -U rwx -G rwx -O rwx file1 file2 ... The lowercase options will add permissions while the uppercase options will remove permissions. Each of the switches is optional and should be interpreted as the ones in the Unix command chmod(1), you can review...
Instruction: Create a UML essential use case model for a new library management system. Use a UML s/w tool to do the work (i.e. MS Visio or LucidChart). A narrative description of the use cases in your model (select one or two for practice) is also required. A narrative template is supplied in this document. To complete the use case narrative, you may make assumptions or create data points as needed. A use case is a depiction of a to...
Draw a activity diagram for Use Case: Check Out Books Primary Actor: Worker Stakeholders and Interests: Worker: wants fast, and easy check out to books. Patron: wants fast checkout, and does not want to be charged for books they did not checkout. Library: wants fast checkout of books, and wants to make sure that all books that leave the library have been checked out. Wants to allocate books fairly. Government: wants to protect investment in books and keep costs down....
When your program does file l/O what should you always do? O Use relative file paths O Use absolute file paths Create a new file for outout O Close files so that others can use them
CSCI 111 Assignment 4 Aim: To write some programs using loops, arrays and library functions. Procedure: Part A: Consider an apartment block which has 40 units. The letterboxes for the 40 units are lined up in sequence outside the building, and are numbered 1 to 40. We're going to play with the boxes. Start with all the boxes closed. Next, starting with box 2, open every alternate box (that is, 2, 4, 6, ...). Next, starting with box 3, change...
In Unix/Linux, input and output are treated as files and referenced by the operating system using file descriptors. When you open a shell session, for example, three file descriptors are in use: 0 standard input (stdin) 1 standard output (stdout) 2 standard error (stderr) By default, the command interpreter (shell) reads keyboard input from file descriptor 0 (stdin) and writes output to file descriptor 1 (stdout), which appears on the screen. As you explored in Lab 2, input/output can be...
AA. Final Project - Improved JavaFX GUI Personal Lending Library Description: In this project we will improve our personal lending library tool by (1) adding the ability to delete items from the library, (2) creating a graphical user interface that shows the contents of the library and allows the user to add, delete, check out, or check in an item. (3) using a file to store the library contents so that they persist between program executions, and (4) removing the...
PLEASE USE F# PROGRAMMING LANGUAGE: NO LOOPS OR CORE LIBRARY FUNCTIONS. ONLY USE RECURSION. Problem 3 (10 pts) Define a function rev that takes a list xs and returns it in the reverse order. • F# standard library has List.rev, do not use it. You need to reimplement it. In [ ]: let rev (xs: 'a list) In [ ]: // Test you function List.rev [] = rev [] |> printfn "%" List.rev [1..9] = rev [1..9] |> printfn "%b'...
This assignment uses functions, files, and strings. Enough flexibility is provided for you to apply your knowledge of basic C++ programing to develop your solution. Develop a functional flowchart and then write a C++ program to solve the following problem. 1. Create a text file named file1.txt and write your brand of car (like Honda, Toyota, etc) in the file. You will be reading the name of the file from the keyboard as a string, using the string class. Your...
