I am creating a to-do list application and to store the tasks on the list, I am trying to create a linked list. the code for it so far is as follows:
public class Node //Class for nodes which make up a linked list { //Declaring the data to be stored in each node and next variable to point to the next node public string title; public string description; public string priority; public string finish; public string complete;
[Code] ....
The problem with this arises when I try to create a new node from another class like so:
createForm create = new createForm(); //Creates an object reference to createForm create.ShowDialog(); //Shows the createTask form for creating a new task //Declares variables and stores the return value of methods in createForm string _title = create.getTitle;
[Code] ....
The variables _title etc.. all store values from text boxes as string. However, the code creating the object says the the variables cannot be implicitly converted from type 'string' to 'int'. Why this error is happening??
I have been programming a lot in Java lately which made me forget a few things in C++. So I tried doing a few simple things. I am having a hard time splitting up a mega string of 6000 names. However I did break them apart as far as their appearance in the console. But I tested it by placing it into a vector and it is still a mega string.
The following code shows bad memory access error (segmentation fault) when I run it. It does this right after it asks for name and the user has entered it.
#include <iostream> #include <sstream> using namespace std; struct Name { string first; string last;
i have an array of strings that i need to split into 2 different string.
Code:
string title = " "Rebecca" "Alfred Hitchcock" ";
so far all the data is in one string called title //need to break them into 2 strings, title and director // title should contain = Rebecca // director should contain alfred hitchcock
which string fuctions can i use to split these 2 and remove the quotes???
I'm having trouble with this code. What I'm trying to do is to read a line from a file and cut that line into two pieces, one is the keyword and the other is the definition. I want to read up to when there is a dash and assign that line to key and then assign the rest of the line to def. After that I copy key to the struct DictEntries.key and def to DictEntries.def. The output of this shows only the definition for both DictEntries.key and DictEntries.def but if I use "puts(key);" I see the keyword.
I have been looking everywhere, but the only place I have seen it done is Objective C. The Question: how do I split a string, input by the user, into an array of characters? No code shown because I know no commands that do this.
I have a list of integers that i wish to store in some kind of array. However i do not know how many integers are needed to be stored each time i run my program so i therefore cannot define a size for my array.
For some reason the integer array, arr[100][50], declared in main is not storing the correct values when passed through the function charArrayToIntArray.
I made an output right in the function to show how the array is not keeping the proper values, although when I output the array from within the loop in the function, it shows the correct values.
I am trying to create a program that will give me an value for a chosen from the user array ut I believe the program I've made does not recognize the values of the previous arrays. (Here is my program):
#include<stdio.h> int main() { int n; int i; int j; float c; float a[10000];
[Code] ....
There must be problem cause every value I give n(only for n=1 the answer is correct) the result is "a[n] is -inf"
I'm supposed to store the value of a countrys population. Then gather out the percentage that countrys population holds when compared with the global population.
Anyway here's the code:
Code: #include <iostream> long swe_pop = 9644864; int main ()
[Code] .....
The result I'm getting is 0%.
I was under the impression that long (or long long) integers could hold high values. And that I could then divide these and answer with a float type value. Giving space for the decimals.
The problem deals with writing a program to geta series of integers from a user and storing those values into an array. Then use a function called selection_sort, when given an array with n elements, the function must sort the array from smallest to largest values.
I have code, and im trying to get it to compile but im getting these implicit declaration errors and conflicting types. Here is my code and the compiler errors.

I know how to do this in c++ with fstream and std::string and getline and so on and so forth. Im writing my code solely in c however. I can't get g++ installed so figured it was a good excuse to learn c instead of using the equivalent c++ abstracts.
My problem is, I'm making a game in c that I have made in c++ but have ran into an issue with my map. I want to read in my map from a file which just looks like this: Name of Town * * * * * * * * * * * * * * * * * * * * * etc...
so i tried using fscanf to first read in the name of the town (stored in a char*) then read in the characters (in this case '*')(not including white spaces becuase i can just print those) into another char*. what is the better way to do this?
I am trying to use C# with C++, two different applications that work together.
In C# it is easy to get a byte array out of a string, by just using Encoding.Default.GetBytes(of-this-string);
I can pass bytes to my C++ program by just writing in the embedded resources. But this won't allow strings, as far as I know it can only be a byte array. C++ reads the embedded resources a LPBYTE.
So I try to send the string or message in byteform.
However the problem in C++ is that there is no Encoding.Default.GetString(xxx)
Would there be any other ways to send a message/sentence in bytearrayform and request it in C++ back to the original string?
I was wondering if this was even possible and if so, how do I do it.
else if (speech.ToLower().Contains("truck") && speech.EndsWith(number)) { Here I would like to see if my speech had ended with any of the values i would have stored in the string "numbers". If it did, I would like to just take the value and add it to a new string called whatever }
I have tried this a million different ways and I cant get it to work. I'm not even sure how I would go about storing tons of different numbers in one string, or if that's even possible.
Im trying to make a c++ program for a school project, and i need to store the information into binary files, but I'm having some problems trying to store a class with string members, for example:
class whatever{ protected: string name; public: (List of functions) }
But if I do that, my code just dont work when I write and read a binary file, but if I change the string to char array, for example:
class whatever{ protected: char name[20]; public: (List of functions) }
It works good, so I wanted to know if there's some way to store a class wiht strings in binary files, or what am I doing wrong?
I am trying to assign the integer value to unsigned char array. But it is not storing the integer values. It prints the ascii values. Here the code snippet
The values which are stored in uc[] is ascii values.I need the integer values to be stored in uc[]. I tried to do it with sprintf. but the output is not as expected. if I print the uc[i] it should diplay the value as 0,1,2....99.
#include<iostream> #include<string> using namespace std; string strip(string message) { //removing elements that is not A-Z or a-z string stripped; for(int x = 0; x < message.length(); x++) {
[code]....
The output in my code shows like this:
[e]Encipher [d]decipher [x] Exit Enter choice: e Enter message to Encrypted: i love you Enter Key: love
The encrypted message is: tzjzpmjy
Back to main menu? (y/n):
However , I want the output to display the spaces as the user's input.
ex. The encrypted message is: t zjzp mjy.
This is the same as i love you in the user's input.
I've been having issues trying to figure out how to add a string prompt along with two int values into a function. The program is complete outside of the getValue function (which gives me errors when trying to run with it included)
Code: #include <iostream> #include <iomanip> #include <string> using namespace std; //Symbolic constant for the value of PI
[Code] ....
I believe it works correctly outside of the getValue function issue.
I have a char correctAns[100] which is empty when initialized. i want to make it hold a different string for each section, so i can use strcmp to compare the correctAns to the answer given by user. here is code
#include <stdio.h> #include <string.h> int main() { char answer[100]; int checkAns; char correctAns[100] , incorrectAns[100];
