i want to make a function that returns a list of strings
i have this code in vb.net
Public Class Addonloader
Public Enum AddonType
IGraphicalAddon = 10

but when i try to debug it, i get this error
"Expected class, delegate, enum, interface, or struct"
and it underscores list <system.type>
I want to make a string array from strings in a text file. Itry to do this but i couldn't do, where is my mistake?
Code:
#include <stdio.h>
#include <stdlib.h>
int main(){
char cumle[100],*c,*dene[50];
FILE *input;
input=fopen("input.txt","r");

I am looking for a function or algorithm to best merge and sort similar content between two lists of unordered strings each in individual files (very large files ~200mb each).
For example, these files have a common first string and are merged based on them:
File 1:
red, apple
green, truck
blue, car
yellow, ball
orange, candy
File 2:
gold, necklace
green, tree
yellow, sticker
blue, water
red, bag
I am looking for the following output:
Output:
red, apple, bag
green, truck, tree
blue, car, water
yellow, ball, sticker
orange, candy
gold, necklace
How can you make a linked list without having to write
node *head = NULL;
head = new node ( "zildjian" );
head->next = new node ("sabian");
head->next->next = new node ("paiste" );
I have a problem set where i have to read in numbers from a file as strings, convert from strings to integers, and pass the integers into a linked list, where each integer is a node. This is what I have so far:
Code:
# include <stdio.h>
# include <stdlib.h>
# define MAX_INT_SIZE 10000
typedef struct integer BigInt;
struct integer {

You need to write a permute class that will take first and second strings to rearrange letters in first, followed by second. For example, if the first is “CAT” string and second is “MAN” string, then the program would print the strings TACMAN, ATCMAN, CTAMAN, TCAMAN, ACTMAN, and CATMAN. The first and second strings can be any length of string or a null.
The permute class uses a Note class as link list note to link all letters arrangement. The permute class has Note pointers, firstNote and lastNote, to point to the beginning and ending Notes of the link list as private data members. There are three other private data members (total, firstString and secondString) to store the total possible number of arrangements and strings pass into the class.
Write a driver to test the permute class to pass in any two strings of any sizes.
Other than mention in the following, you can add more classes, functions, and private data members to this program.
Note class
The Note class needs to have two private data members and a constructor. The two private data members are data and p pointer. The data’s data type is string and p pointer is Note. The Note class constructor has two parameters, one is string and the other is Note pointer.
Permute class
The Permute class has five private data members (*firstNote, *lastNote, total, firstString and secondString). The firstNote and lastNote pointers are point to Note. The total has integer data type. The firstString and secondString have string data type.
There should have at least three public member functions, Permute, permutation and print. The Permute function is the constructor which takes strings to initialize the private data members. The permutation function does the recursive call to arrange the strings and setup the link list. The print function will print out the private data member information.
Driver file
The driver file should declare a Permute eight elements pointer array. Instantiate eight Permute object with the following eight set of data and assign the object to the pointer array. Use a repetition to call the object’s print function to print out the private data member information. If the total of the permute private data member is less than 100 then print out the permutated letters four in a row, otherwise print out 9 in a row.
first = "", second="",
first = "", second ="CATMAN",
first = "C", second ="ATMAN",
first = "CA", second ="TMAN",
first = "CAT", second ="MAN",
first = "CATM", second ="AN",
first = "CATMA", second ="N",
first 1 = "CATMAN", second ="";
Basically I need to make a program which asks for a business name and then keeps asking for more until user doesn't want to. Once more than 1 business is enter it should display the business and sort it alphabetically and keep displaying them each time another is added. I am lost on how to store the added business, sorting it and displaying the list.
Here is what I have so far.
#include <iostream>
#include <string>
#include <algorithm>
#include <vector>
using namespace std;
int main () {
string business_name;
char selection;

If I wanted an int connected to a float connected to a string connected to a POD, would all I have to do is :
Code:
template<class T, class X>
struct node {
T data;
node<X> *next;
};
Or would I be forced into using polymorphism?
OK I'm making a simple program to make a shopping list. I would like the program at start up to load the previous shopping list that was saved as a text file. The format is one line per entry which consists of the category or Isle, and the item description. Here's an example:
3 Dog Food
Produce Sweet Onions
I reading the first word, and then I want to read the rest of the line which may have more than one word... the problem is my code hangs... or goes into the old infinite loop. It doesn't see the end of file.
Here is my code:
void
addItemsFromFile(vector<item> &shoppingListVector) {
string word;
char buf[30];
if (fileExists("shoppinglist.txt"))

So for class I have to make an array of structures for a basic contact list in a phone.
I understand the bones of the program and how to go about doing most of it but as far as arrays of structures go I am blind.
Code:
struct phone
{
char FirstName[16];
char LastName[16];
int Number[11];
};
struct phone numbers[friends]; //friends is a variable assigned by the user What I am a bit confused about is say the user enters 30 as how many friends they have. How would I assign a value to the 3rd struct for LastName?
I am trying to make a linked list. When I compile my code, I get an error saying 'current' is not declared in this scope. I don't understand because I have declared in the first line of my functions body. The variable is local to the function so I don't understand what the problem is.
#include <iostream>
#include <cstdlib>
using namespace std;
class LinkedList {
public:
LinkedList() // default constructor makes an empty list

I am programming a translator, and I have it so that it detects words with spaces both in front of and behind them, so I did "string.append(space);" where space equals " ". That added a space to the end, but I still need a space added to the front.
View 1 Replies View RelatedI have a problem who must print the sentences who have lenght more than 20 characters. I dont know why, but it prints just the first words. Look what i made.

For instance :
Give the number of sentences : 3
First sentence : I like the website bytes.com
Second sentence : I like more the website bytes.com

From HP / Microsoft (Visual Studio C++) <list>:
Code:
struct _Node
{ // list node
_Genptr _Next; // successor node, or first element if head
_Genptr _Prev; // predecessor node, or last element if head
_Ty _Myval; // the stored value, unused if head
};
The stored value is wasted space for the list head. Is there any advantage to implementing list using the same structure for a list head and node?
Code:
// Write a function called insertEntry() to insert a new entry into a linked list.
Have the procedure take as arguments a pointer to the list entry to be inserted (of type struct entry as defined in this chapter), and a pointer to an element in the list after which the new entry is to be inserted.
// The function dveloped in exercise 2 only inserts an element after an existing element in the list, thereby prenting you from inserting a new entry at the front of the list.
(Hint: Think about setting up a special structure to point to the beginning of the list.)
#include <stdio.h
struct entry1 {
int value;
struct entry1 *next;
};

This is a working version of the exercise, but I don't think I'm doing what's asked. I was able to add an element to the beginning of the list using an if statement, not creating a special structure that points to the beginning of the list. How would I go about creating a special structure that points to the beginning of the list to add a new element at the beginning of the list?
I'm trying to display a list of MSMQ messages in a list box based on a drop-down list holding the environment.So i've setup the binding and i know that the list loads but nothing shows up in the list? I should be setting like a display member or something but i'm not entirely sure

I tried to add 2 or more strings together but failed.
eg I would like to add "KK" & "LL" together by adding but it couldn't work.
string string_B = "KK";
string string_C = "LL";
string_A = string_B + string_C;
1. I finished reading a beginning C book, and in the section about arrays, it says that one string can fit in a character array (char arrayname[]) but there cannot be a string array (string arrayname[]) that have multiple strings. Is
Code: string arrayname[4] = {"one", "two", "three"}; not valid?
My compiler lets me run it and it works, but why is the book saying it's wrong?
2. I know you can represent multiple strings in a character array by:
Code: char newarray[10][4] = ("one", "two", "three");
because [10][4] indicates that there should be four newarrays created with a max of 10 characters each, but is
Code: string multiplestrings[10][4] = ("i love you", "hello come to me", "i don't get C"; "hello world", "what are arrays"; "i am happy", "I am learning how to code"); valid?
Does multiplestrings[10][4] basically create 4 string arrays that have a maximum of 10 different strings within each string array?
How join two strings? basic reason is add given filename little text to end. I try do by hobby not school project program which converts files format x to format y.i dont say which formats becouse reading and writing is almost done. (only little amount code is needed).'
