C++ :: Making List Of Champions - Vector Of Class
Oct 6, 2013
I am making a simple program that is suppose to make a list of champions and their items from the game League of Legends. I am stuck on making a vector of the class so each slot within the vector would hold each champion and its data. This is what I got:
Champion_Info.h
#ifndef CHAMPION_INFO_H_INCLUDED
#define CHAMPION_INFO_H_INCLUDED
#include <vector>
#include <string>
using namespace std;
class Champ_Info
[Code] ....

I'm trying to make an templated class of List and trying to make a list of Students(another class) which I made. Its not working.
Code seems to work fine for pre-defined data types but it crashes when it comes to students. I also want to run sort function on list of students.

I have a .cpp file which contains 5 smaller defined classes. In my missile class I have a default constructor and a constructor that I invoke
class Missile{
private:
bool isHuman;
[Code]...
My issue is when creating and adding the pointer object; it doesn't seem to create a new instance of the class-the Missile objects all share the same xPos value which is always the first xPos when the "fire" command is given. The "Missile *missile = new Missile(xPos, yPos, true);" line does not seem to create a new instance of the object with different variables but instead creates a new object with the same variables. Is it necessary for me to always make a separate .cpp and .h file for any class I want to create multiple instances of or can I keep the smaller classes in the same file and still create a new separate instance of the class?

I have a 2D array, array[20][3]. Each row represents a storm and each column represents month #, wind speed, and pressure in that order. This data is read from a file and auto-fills the array. I need to be able to give users the ability to add an additional storm or delete a storm. I know that a linked list would be the best approach but I'm not very familiar with linked lists.

I want to make something like this for a game:
It is a "list box" that has 2 scroll buttons (scroll bar not needed). One button push, "scrolls" the list one entry.
Needs to run crossplatform (windows, linux).

I am having some serious issues with class inheritance. I am trying to make a MoneyBag class inherit from a class called bag. This will not work. I get an error complaining: error: expected class-name before '{' token. And yes I have googleing it and tried several of the various solutions offered with no avail.
The MoneyBag is pretty simple right now as I wanted to get it connected to bag before I tried to do anything with it.
//MoneyBag.h//
#ifndef MONEYBAG_H
#define MONEYBAG_H
#include <bag.h>
class MoneyBag : public bag{ ////<<------ Error appears on this line.
[Code] ....
So based on everything I have seen on line the statement:
class MoneyBag : public bag{ is legal.
As it is done this way on this very site's tutorial:
class Rectangle: public Shape, public PaintCost{

I'm trying to make a class constructor within a namespace and I keep getting errors like: "'<variable>' is a nonstatic data member of class '<class>'" for when I try to setup parameters, and "Incomplete type is not allow" whenever I try to write out my function definition. Here's what I'm doing:
namespace test {
class blah;
} class blah {
typedef int var[5];
[Code] .....
Also I'm unsure why there is a parameter of 'const blah &' when I mouse over blah(); (using Visual Studio 2010) within the class definition. It tells me 'blah::blah(const blah &)' and I am unsure where the parameter comes from. How can I resolve these issues?

I'm trying to make a very simple game in SFML, and i have a problem. Whenever i try to create sf::Sprite for the class where all properties of Player (his sprite, health, speed, etc.) It gives me error.
#include <sfml.h>
#include <list>
class Playerclass{
public:
int xspeed, yspeed;
float health;
sf::Sprite entsprite();
[Code] ....
The error is with player.entsprite.setTexture(texture) : "'player.Playerclass::entsprite' does not have class type".

Something like that:

...
public:
string m_name;

Im creating the vector on main() and using push_back with a pointer to an initialized CDummy instance

I am making a console based database system. Because I have to keep inserting, editing , deleting data blocks from my record file I have decided to use either vectors or list to store the all records. From the file I shall read the entire vector/list and work with it to add , remove or edit record and then again write the entire vector/list to the file again. I figured it would stop all the weird things that happen when directly working with the file. Is it an efficient way ?Or is it totally unnecessary ?Is there a better way?

vector<int> vec1 {2, 4, 6, 8, 10, 12, 14, 16, 18, 20};
This code worked perfectly fine in Xcode earlier today, but when I got home on visual studio 2012 express it is having an error. It's saying that the local function definitions are illegal and has a red mark under the '{' only?

How can I write my own container which has properties of both vector and list.
E.g. I can access elements directly using [] operator like vector and behave like list in terms of memory (means we don't have to shift elements if we want to insert in between like list)....

I was assigned to print a linked list but as a vector of char (I cannot use the normal string type) , this is what I have:
char* List::asString(){
Node* ite = new Node();
ite= first;//ite is like an iterator of the list
for(int i=0; i<sizeOfList; ++i){//sizeOfList is the total of node of the list
[Code] ....
But when I print that, I get a bunch of weird symbols...

I was trying to implement own vector class and wrote some code. Below is the code.
Code: #include<iostream>
#include<vector>
using namespace std;
template <typename T> class MyVector
{
T *mem;
int m_size,final_size;
public:
MyVector() : final_size(1),m_size(4)
{
[code].....
I have question on this function.
Code: myVecPush_back(T t){}
Here I was able to put elements upto any number of time, but I have allocated memory to only 4 elements in T *mem.
My question, why the program is not crashing when I tried to put elements more that 4?
Is since the variable is of type Template? Any specific reason for this?

Let's say we have a custom Vector class and I need to know which of the following is considered to be more efficient and why of course.
Vector Vector::operator+(const Vector &b) const {
return Vector(x+b.x,y+b.y);
}
Vector Vector::operator+(const Vector &b) const {
Vector tmp(x+b.x,y+b.y);
return tmp;
}

Okay so I have a class Student, which takes a number and a vector as a parameter for the constructor. Everything works well, until I output the values of the vector for every instance. The problem is that the same vector is being shared with EVERY instance I create, but I want it to be unique for every single one!
//Student.h
#ifndef __Grade_calculator__Student__
#define __Grade_calculator__Student__
#include <iostream>
[Code].....

So I'm trying to store class objects in a vector:
#include <iostream>
#include <fstream>
#include <sstream>
#include <string>
[Code]....
1. Am I storing it correctly?
2. How would I access the stored data, say, if I wanted to compare it to other stored data or COUT it?

What I want to do with the below code is to construct the vector containing 'Ability' objects in the class 'Card'. I have searched for the solution in the past, and have been unsuccessful, mainly because the vector contains child classes of the parent class 'Ability'. The below code is a snippet of the larger program that I am working on, and should compile:
main:
Code:
#include <cstdlib>
#include <iostream>
#include <vector>
#include <string>
using namespace std;
#ifndef _abilities_h_
[Code] ....
As you can see, in the class 'Card' I have a pretty large constructor. Up to this point, however, I have failed in my attempts to construct the abilities vector, because it contains those child classes.

For a beginners C++ lab, I have a base class Employee and two derived classes HourlyEmployee and SalaryEmployee. In main, I have a vector defined as vector <Employee *> VEmp; It's then passed to a function to get the input, which works fine. But what I'm struggling with is another function with the header "printList(const vector <Employee *> & Ve)". It's supposed to loop through the vector and call the appropriate printPay function, which is a seperate print function inside each derived class. How do I loop through the vector and print it out? I was trying to do a for loop and something like "Ve[i].printPay();", but that doesn't work. So how would I do it?
Here's some snippets of the relevant code.
class Employee {
....
virtual void printPay() = 0;
};
class HourlyEmployee : public Employee {
[Code] ....
