Here STRING is a user defined class. how to assign a constant char array "FOOBAR" to string object? Copy constructor need to be same class type as parameter. and overloading assignment operator also need to be same class type. I think 'friend' can let pass another type of object rather than STRING to do operation on overloaded '=' operator. How could it be done if it is possible at all?
I got this program to create an array of playing cards and assign the values and suits and shuffle the array. I'm at the point where I need to output the cards but I need to burn the first card by making it output "**" instead of the card. my cards[] is a constant so I can's assign the first card as such.
void showCards(const int cards[], int numCards, bool hideFirstCard) { if (cards[0]) { hideFirstCard=true; cards[0] = '**'; } for(int a = 0; a <= numCards; a++) { cout >> showCard(cards[a]); } }
Write a program using user-defined function which accepts an integer array and its size as arguments and assign the elements into a two dimensional array of integers in the following format: If the array is 1,2,3,4,5,6, the resultant 2D array is
I'm trying to make an unordered_map with a key of std::string and a data type of my own class, "Variable". This is my code that I've done:
#include <iostream> #include <sstream> #include <string> #include <unordered_map> class Variable { // The class that I want to have as data type public: Variable(double value) : _value(value) {}
[Code] .....
This code works just fine when I use double instead of "Variable", but the moment I put in the class "Variable" instead it gives my this massive error:
Why would you ever assign a pointer to an existing array?Take this link for example. URL....I understand that pointers use dynamic memory allocation so they are much more flexible then a built in array, but if you already have an existing array, don't you already have static memory allocation for that array? Why bother assigning a pointer? Regardless of the pointer, doesn't the program still allocate static memory to the array anyway?
I am trying to solve some random puzzles so I do not lose/forget c++. I never used hashtables in C++ and decided I needed to brush up. I am having in creating a hashmap that holds objects with a string as a key:
Code: #pragma once #include <iostream> #include <unordered_map> class WordCount
How to assign numbers stored in a buffer memory to a 2D array.
The data type is unsigned 16bit (unsigned short) integers and they are stored in a 16bit/2bytes*1280*1024=2621440 bytes memory. The pointer pBuffer is the starting address of the buffer. Now I initiated an array and then assign the numbers to the array.
I am trying to make a basic app that will loop through an unordered list with repeats and count how many times a specific item repeats. Example would be I select a state from the list box and it will tell me how many times it is listed.
This is the code I have up so far, trying to keep it basic. I am missing something, something related to the counter? I think I have some of the better half up but I am not sure...
Code: Private Sub ListBox1_SelectedIndexChanged(sender As Object, e As EventArgs) Handles lstBox.SelectedIndexChanged
Dim wins As String = lstBox.SelectedIndex Dim foundwins As Boolean = False Dim i As Integer = -1
what I need is to get the first integer from a file and assign it to a variable and the others integers to an array. Example: Thats my file content 5 4 6 7 8 0 and that would be the code:
I have been given an assignment which I understand pretty well, but I have a problem, and haven't been able to find a clear solution anywhere. I'm sort of a beginner in all this, so it's hard to understand what some people say.
So basically what I wanna do is assign a set of grades to every element in an array of a set number of students. I already have the part where you ask for the number of students you want to enter and then ask for their names and grades, but it can only enter one grade, and I can't figure out how to assign several grades and then get the average.
Here's my code, the assignment said to do it like this.
#define MAX 100 #include<iostream> #include<stdlib.h> #include<string.h>
I'm trying to figure out how I can create a vertex array object at offset of a vertex buffer object.I've created the buffer object. I'd like the "texs" idnex data to start at the texture coordinate content of the vertex_t structure.
Type definitions:
struct vertex_t { vector3d_t position; float s; // Texture coordinate s float t; // Texture coordinate t };
Code so far:
// How do I make this start at a certain spot of the VBO?! glVertexAttribPointer(texs, 2, GL_FLOAT, GL_FALSE, sizeof(vector3d_t), nullptr; //...
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.
I am writing a program for a poker game.. I created a class to get cards and create deck.. the problem I am having now is how to deal 5 cards to an array to ve evaluated later. I want to call the array player1[5]. I tried to use pointer but I get the following error
I am trying to write a poker program. I created a class to create a deck of cards..and then shuffle the deck..Now I am trying to pass value from the deck to an array to deal a hand..so 5 cards to player1[] array.. I tried doing it directly such as.
But I would get error such as [Error] no match for 'operator=' in 'player1[j] = deck[j].Card::toString()'
So then I tried using a pointer..
char *getCard; getCard = new char; for (int j = 0; j < 5; j++) { getCard=deck[j].toString(); }
but I would get this error [Error] void value not ignored as it ought to be. So how can I pass a value from the object deck..to an array? or should I be doing it another way?..I tried to think of a way to do it via a function but really got hung up there..
I'm struggling loading a class (and it's two derived classes) from an input file. I'm trying to create an array of class objects (and derived objects) and then load them based upon what is in the file.
Main class: Code: class Book { protected: string sTitle;
[Code].....
Basically if the getline get's a P it's supposed to create a new object using the PrintedBook derived class and then store it to an array, if the getline get's to the "A" it's supposed to create an AudioBook object.
What I'm struggling with is writing something to parse the file line by line and create the objects on the fly and then store them into the array.
I am trying to delete a speific element in an array of class objects. i am overwriting the element i waant to delete with the element after it. My algorithm works but the output is not correct, after debugging it seems my objects just dont copy, is there a way to copy a class object, i have looked up copy constructors and attempted to write one but it does not seem to have any effect on the output.
below is my code
class user { string firstname, lastname, currentteam, position, status ; int age ; public: user() {};
This problem just seems really strange to me because it is simple yet for some reason my class cannot pass into another class. The class PASS_OBJECT has a static array (even with 1 element this doesn't work) and when I try to pass this class (after it is initialized) I seem to lose the data inside the PASS_OBJECT. Not only that but even when I declared the class OBJECT with the type of PASS_OBJECT<int> I seem to lose the integer 99. Here's the code, note that if you comment out line 89, 92 and 93 you will notice that line 90 outputs In main 2: 99 just fine but it doesn't otherwise???
#include <iostream> const int size = 1; template <class T> class PASS_OBJECT; template <class S> class OBJECT {
