Hi all, So I'm trying to learn how to do a hash table with separate chaining, but it is giving me several issues. The hash table I'm trying to make will hold instances of a class named Person and uses Person's data member phonenumber for the key. Currently, the main …

I am trying to solve a system of 5 equations in 5 unknowns. I am new to the Matlab language. I consulted the documentation and decided that the best way of doing this was to use the solve() function. However, this function does not appear to work properly for 5 …

Hey everybody, So I though that I understood linked lists and arrays well enough to make a hash table with separate chaining. Theoretically, it seems trivial, but I am getting a runtime error. The error appears to arise from the line head = heads[i], where head is a node pointer …

Hi all, So I'm currently teaching myself about hash tables. I'm doing a programming challenge where I create a hash table that stores instances of a class Person, with data members for name, phone number, and GPA. The table uses separate chaining to take care of collisions. The node I'm …

Hi all, I've been working on making a bounded priority queue implemented as an array of queues and I believe I have it at last -- except of course for this error that I don't understand... I am getting an error about the queue array being declared without a type …

Hi all, So I have reached a kind of impasse on my current project. I'm trying to make a program that can function like a phone book, loading information from a file into a binary search tree and performing operations on said information. The issue I'm having appears to be …

Hi all, So I'm working on this program to use a circular doubly linked list to implement a queue class. It went fairly well, but I'm stuck on the copy constructor, which causes runtime errors whenever I try to test it. Nonetheless, I really don't see what I am doing …

Hello all, So I'm working on this simple program with a Queue class template that is publicly derived from the abstract base class CharQueue. The only problem is that I keep getting hit with the error "expected class name before '{' token". The reason I don't understand this is that …

Hi all, So I'm working on this program to detect if the w' in a string in the form of w$w' satisfies the condition that w' is the reverse of w. The only problem is that I have a logic error that I don't understand. If I input the string …

Hey Everyone! So I'm a super beginner trying to teach myself the ins and outs of stacks (ever so slowly). Specifically, I'm trying to work out a programming challenge in which the objective is to write a function to tell if a string in the format of word1$word2 satisfies the …

Hello everyone I have been trying to learn the greater mysteries of linked lists and have come across an error that is inexplicable to me at my current level of understanding. I have written a program that attempts to form a linked list to store student information in the form …

how would i make a new type of variable, like instead of int or double? would i use classes or something like that?

Hi everyone I am trying to write a program that will allow to people to play tic tac toe. My constraints are that this must be accomplished mainly through the use of functions and that the default cell field for the displayed game board must be stars. I am having …
