I am having a bit of difficulty with implementing an object oriented program that uses both linked lists and operator overloading. The program calls for adding and multiplying polynomials together, with each single polynomial being represented as a node of a linked list (which is further a data member of an object of a class I have defined to implement this program). For example:
polynomial A will be: 3x^4 // 1 node of a linked list polynomial B will be: 5x^2 // 1 node of a linked list polynomial C will be blank for the time being. // empty list
Now, I need to use operator overloading so that this following line of code can be implemented:
C = A + B;
C should now be: 3x^4 + 5x^2.
The checklist of which parts of my code that work:
constructor works; copy constructor works; destructor works; operator= works; print function needs work but i can worry about that later; operator* work on later
Here is my code:
#include <iostream> using namespace std; struct termNode { int exp; // exponent int coef; // coefficient termNode * next;
[Code] ....
For the time being I need to add multiple nodes together (with the result being in descending order). So for example:
polyType a(2,3), b(4,5), c(6,7), d; d = a + b + c; d.print(); // should print out 7x^6 + 5x^4 + 3x^2, but it will only print out: 3x^2 + 7x^6
I want to extract polynomial coefficient out of a string recieved by input, for example if i enter 4x^3+2x^4+3 , the resulting out put be : 2 , 4 , 0 , 0 , 3
The goal of this is to create a list of polynomials as a <Pol> vector, where Pol is the class I developed. It "reads" the .txt, gets the strings, transforms the polynomials in the strings into class Pol objects, and it places them in the polynomial vector.I remove the strings from the text where the polynomials are, and I convert those polynomials(in string) to actual polynomials ( "Convert" in MPol.C ,bellow) , but in line 169 from Mpol.C , when I try to put "temp" ( the highest degree of the polynomial), i get a "memory corruption" error or similar. However if instead of "temp", I place "temp+1" I no longer get any errors, but i get an extra coefficient.
namespace main_savitch_5 { class polynode { public:
// CONSTRUCTOR: Creates a node containing a specified initial coefficient (init_coef), initial exponent (init_exponent), and initial links forward and backward (init_fore and init_back).
Every time I run if(color=="1") it's supposed to add 1 to redTotal. However, every time I run if(color=="1") if get 1 for redTotal every time.
(Write a program that provides the option of tallying up the results of a poll with 3 possible values. The first input to the program is the poll question; the next three inputs are the possible answers. The first answer is indicated by 1, the second by 2, the third by 3. The answers are tallied until a 0 is entered. The program should then show the results of the poll—try making a bar graph that shows the results properly scaled to fit on your screen no matter how many results were entered.)
Code: #include <iostream> #include <string> using namespace std; int main()
I am new to c and I have come across a problem when adding other functions to a programme and printing the values. The question I am attempting to solve is :
The following function computes ex by summing the Taylor series expansion to n terms. Write a program to print a table of ex using both this function and the exp() function from the math.h library, for x = 0 to 1 in steps of 0.1. The program should ask the user what value of n to use.
double taylor(double x, int n) { int i; double sum = 1.0; double term = 1.0; for (i=1; i<=n; i++) { /*Or we could have written: */ term = term * x / i; /* term *= x / i; */ sum = sum + term; /* sum += term; */ } return sum; }
My code is
Code:
#include<stdio.h> #include<stdlib.h> #include<math.h> /*Taylor series for e*/
[code]....
code prints out the values for exp, but it gets stuck in the Taylor function and I'm not sure how to solve it.
How would one add each value from an array? I'm working from a string but I was wondering if there was a way to loop through the string and add each value. This is what I have so far:
#include <iostream> #include <cmath> #include <string> int main() { std::string numbers; int sum;
I have the following code in sourceFile.cpp. functionA() is first called and inserted entires for key1, key2 and key3. Then functionB() gets called to use the vectors for the 3 keys. I want to free all memory after exiting functionC(). Among the three ways to put an entry into the map for the 3 keys, which is correct / better?
Class ClassA { ... } ClassA *key1 = new ClassA(); ClassA *key2 = new ClassA(); ClassA *key3 = new ClassA();
Currently in development of a cookie clicker clone (for fun)
I am stuck at the idea of the "Cookies Per Second" thing.
Is there a way to implement a per second adder thing that doesnt actually effect the game play (eg even though the player may not be pressing C every second a cookie (or more) will be added, or if they can press C more than once a second, every second a cookie will be added... If you get what I mean).
I need to input values for two arrays and then add the two with all of it being print visible. I have this so far but can not figure out how to add the two arrays.
#include <iostream> using namespace std; int main () { { int const ROWS = 3; int const COLUMNS = 3; int square[ROWS][COLUMNS];
'm new to programing and I'm trying to get this program to add up a price of coffee to the add on extras such as cinnamon, etc. But once the program runs it doesn't add up the coffee price with the extras and I've been at it for hours...
Code:
#include <iostream> #include <cstdlib> using namespace std; int main()
This is my code without malloc. I need to change the array size so there is no max size for each matrix. I must dynamically allocate space for all arrays used. So I need to use malloc to create my arrays. So I cant use int A[rows][cols].
Code:
/* This program asks the user for 2 matrices called A and B, as integers, and displays their sum, C. The max dimension of each matrix is 100. */ #include<stdio.h> // Construct function void construct() { int m, n, i, j;// Variables int first[100][100], second[100][100], sum[100][100];// Matrices variables
[Code]...
Im having a hard time understanding/using malloc. Should first, second, and sum be single pointers or double? How do I scan the matrix correctly? And how do I add them properly? Do I have to change my for loops?
Code:
/* This program asks the user for 2 matrices called A and B, as integers, and displays their sum, C. The max dimension of each matrix is 100. */ #include <stdio.h> #include <stdlib.h> // Construct function void construct()
I am currently working on a program and Originally I was to create a bash program to extra information from youtube and create a table of users, views, titles, duration, etc. (I sent each to a txt file)..Then I was to create a C program to use the extracted information. In this case Users and read in the conents of user.txt and construct a linked list to hold the information. Then print from the Linked list.I managed to do that,
What I have to do now is start reading in The other files and construct a table. And radix sort it by views. But to get to the radix sort part I get stuck on reading in all the files correctly and having the linked list hold them. I keep getting seg faults when I change my code.
I'd like to add a 'command' to my C program. For example if someone types 'get out' it closes the shell and quits. I want the 'get out' command to work like 'exit'. How do I write a code like this
Code: char entry[15]; scanf("%[^ ]", &entry); if (entry = "get out") do "exit";
I am trying to convert a string Input by user into an unsigned byte array.The data would be in hex form like :- "AE 1F 2C". I am thinking of using strtok to split the string into be " ". and then cast to (unsigned char *) . But for that I''ll have to prefix every element with 0X Is there any convenient way and elegant way to do this?
I was trying to solve a problem that required to add one hundred 50 digit numbers. Since there is no way to hold such a huge number. I read that storing them in strings is the way to go. I was caught midway while trying to do the same.
And the text file is this. Code: 123465789 321654987 This isn't the exact huge number, but I wanted to try it out with lower number before trying out with the original huge ones.I am trying to store the numbers in a two-dimensional array. However when I and try to pass the single number as an parameter to the AddTwoStrings() method, It actually passes the entire number as such.
When I pass string[0],string[1] it should pass the first and second number from the files as the two numbers instead of the whole number as such.The function AddTwoStrings() doesn't do anything as of now, I encountered this error when I was testing the code till this part.
I am making a text based rpg for school and im having troubles with it. Ineed to add an inventory into my game and im not to sure as to where or how.. this is what i got for player
#ifndef PLAYER_H #define PLAYER_H //console Util.h includes <iostream> , <string> and <window.h> and defines //the NOMINMAX macro. As a result of including ConsoleUtil.h, PLayer will // also knaow about thoes objects. #include "ConsoleUtil.h"
I'd like to use the Big Integer Library [URL], but I have issues to use it. I'm using Xcode as compiler and I don't know how to include the library in my project files. When I drag all the files in the project directory and write the statement #include <BigInteger.hh> on the top of the declaration of the main function, even whiteout any other code, I get lots of build error on the .hh and .cc file.
I have a basic question regarding 2d vectors. The following code makes a 2d vector and fills it with a matrix of integers. The vector tempVector3 gets added as a new row to the matrix. But what if I wanted to add the tempVector3 as a new column instead. How would this be done in the simplest way?
#include<iostream> #include<vector> int main(){ std::vector<std::vector<int>> numbers; std::vector<int> tempVector1; tempVector1.push_back(2);
I am writing a program to list the 8 planets, then you select which planet you want. it gives you the mass of the planet, the radius, then you use the mass and radius of the planet to find the surface area (sphere formula) and the density of the planet. Along with those options, you have to add and delete a planet from the list and then sort them alphabetically. All i am having trouble with is the adding and deleting part. The code the adding and deleting from the list would go in cases 9 and 10.
