I don't have my complete class but this part of it. public boolean add(String title, int productID){//true or false statement if ( numberOfRecords == list.length() ){ // I get an error here at list.length() return fal...
I'm trying to create a recurring struct method in my code to walk through a binary search tree. But I'm getting errors on compile and unsure what is the cause. I've got Node* findNode(const Node *, const Object &); in the private section of the .h file and Node* BSTree::findNode(const Node* current, const Object &target){ if(*current...
Given: an int variable k , an int array currentMembers that has been declared and initialized, an int variable memberID that has been initialized, and an boolean variable isAMember , write code that assigns true to isAMember if the value of memberID can be found in currentMembers , and that assigns false to `is...
Hi all, I am supposed to write a simple Cinema Booking System, which allows a customer to make reservations for movies. The Cinema consists or different theatres, with different amount of seats, price and movie showtimes.

An array of Strings, names, has been declared and initialized. Write the statements needed to determine whether any of the the array elements are null or refer to the empty String. Set the variable hasEmpty to true if any elements are null or empty-- otherwise set it to false. hasEmpty=false; for (int i=0;i<names.length;i++) i...
So my teacher told me to make a string that makes whatever I type go in the opposite order (e.g. "hello there" becomes "ereht olleh"). So far I worked on the body and I came up with this public class Main { /** * @param args the command line arguments */ public static void main(String[] args) { (The input needs to be in...
Hi all, We are trying to implement levensteing distance algorithm in assembly and calling the assembly function from C code. But we have some char comparison problem and could not solve the problem. Function takes two char* parameters. In the first two lines i mov the these addressess to ecx and edx. iminusOne and jminusOne are indexe...
From the exercises in a book I am using to learn MATLAB: Given x = [3 15 9 12 -1 0 -12 9 6 1], provide the command(s) that will A) set the values of x that are positive to zero B) set values that are multiples of 3 to 3 (rem will help here) C) multiply the values of x that are even by 5 D) extract the values of x that are greater tha...
for(int i=N; i>0; i=i/2) irrelevant statement; I am asked to find the complexity class and I am unsure of whether I am supposed to use Big-Omega notation or Big-O? But I am assuming that it is O(N/2) and then O(N) if I drop the constants. for (int i=0; i<N; i++) for (int j = i+1; j<N; j++) irrelevant statement; ...

I was asked to build a binary search tree after adding about 20 values in a specific order and I finished and found the size to be 16 and the height to be 4. But part (c) of the question asks me to find the Height (after removal) I am unsure what this means and would be grateful if somebody could clarify what this means. ...
You are to write a program that requests that the user inputs a fraction of the form n/d with d nonzero. Your program then prints out the fraction in reduced form. The program then asks if the user would like to process another fraction and continues to do so as long as the user replies with Y. A fraction n/d is in reduced form provided...
Beginner programmer here! I need to write a simple phone book application. My program should be able to add names and phone numbers to a database. I should use a dictionary to store the information. If the user's input is empty, my program should stop, otherwise it should keep on asking inputs. Honestly I am lost here. I need help. ...
I am making a multiplayer networking game. Now to connect to the server, client needs the ip address of the server. So, the way I implement this is as follows. Client Broadcasts its ip address at Broadcast IP and a port say A. Server listens to it over A, and Server creates a new UDP connection with the client behaving as a client say...
Hi I am about to create a bitmap that holds control of 512 bits, all 512 bits should be 0 to indicate that the bit is free when the program starts. Function occupyDataBlocks(int number) should find free bits put the position of the bit in the array int data_blocks[] and set the occupied bit to 1. Under is some code that does some of t...
Hello, For my graphics class, our professor wants us to keep track of our current matrix on our own and apply rotations/translations/scaling matrices to it then load it using glMatrixMode(GL_MODELVIEW) and glLoadMatrix(current_matrix). All of this seems fine, but when I actually use it, I keep having an issue: if I apply a rotation to ...
Hi, I need to create a Bed module with these functions: readBed(file) – read a BED format file and constructs a list of gene model objects from the data it contains. writeBed(models=models,fname=file) – writes the given list of gene model objects and writes them to a file named fname. For the read...
