First off, this is a "homework" question so vector libraries and string libraries are off limits. I'm trying to get to the basics of c++. My intention with this code is to make and use an array of string arrays. A list of words in other words. When I run this code I get a bunch of nonsense. If there is a better way to make a list of w...
For a Data Structures project, I must find the shortest path between two words (like "cat" and "dog), changing only one letter at a time. We are given a Scrabble word list to use in finding our path. For example: cat -> bat -> bet -> bot -> bog -> dog I've solved the problem using a breadth first search, but am seeking something bette...
Question How can I randomly generate one of two states, with the probability of 'red' being generated 10% of the time, and 'green' being generated 90% of the time? Background Every 2 second either a green or a red light will blink. This sequence will continue for 5 minutes. The total number of occurrences of a blinking light should...
Hey everyone, I was wondering if it is possible to traverse a linked list like this: currentNode = randomNode;//where randomNode may or may not = firstNode prevNode = firstNode; while(prevNode != currentNode } Is it possible to do this in C++ when I am trying to find the node before currentNode in a singly linked list? I trying to...
I am trying to write a program that is given a maze and tries to find the way out. M is the entrance, E is the exit, 1s are walls, and 0s are pathways. It is supposed to find each path and put P in the path. It is supposed to find all available paths. Right now it finds part of a path. Here is the code: public class Maze { private...
For my computer science class, we need to write a program (in C++) that takes an input of characters and outputs the possible permutations of it according to the dial pad on a phone, leaving non-digit characters in place. For example, inputing 2 outputs 2, A, B, C. Inputing 23 outputs 23, A3, B3, C3, 2D, 2E, 2F, AD, AE, AF, BD, BE, BF, ...

Hi, I have a hw question which confuses me on what i have to do. The question is below: The idea is to design a generic function called Modify_If that will take an input x (passed by reference), and two functors f1 and f2. The function Modify_If will use functor f1 to determine whether x obeys a certain condition. If it does, Modify_if...
