I am an IT student currently learning linked list. I have a problem with my code here. After I call addFront() my list doesn't change when I display it. How do I somewhat change/fill my list without changing the function type? I know it works on pointers still messed up with linked list.
Code:
typedef struct node *nodeptr;
struct node{int item;
nodeptr next;};
typedef nodeptr List;
}
[code]....

We have been assigned to create an iTunes library. Everything compiles in my other .h file but my main is not happy with my object declaration. It keeps stating "primary expression before '{'". Here is my main code:
#include<iostream>
#include<string>
#include<fstream>
#include"myTunes.h"
using namespace std;
//function protocols
void read(string);

This code:
#include <iostream>
class Foo {
};
int main() {
Foo foo;
std::cout << sizeof ( foo ) << std::endl;
std::cin.get();
return ( 0 );
}
produces this result: 1
Why is the size of an instance of Foo 1, although it doesn't have any member variables?

It has been a few years since I have had to do this, but I need to declare a method in my base class, but produce no code for it. Then when this library is used by my second project I will derive a class from this base class and put the code into it there. How is this possible? I used to know how but do not remember how now.
The library is a static library designed for linking with both 32bit and 64bit Windows applications to handle a lot of the tedious stuff with Windows programming. The method in question handles specific command inputs. However, since each program that uses this library will have different uses for these commands, I want to leave it up to the user to code their own handling, but require it to be coded in the derived class.

So I was wondering if I were to empty the elements of a stack into a queue, but i only wanted to empty the even numbers or the odd ones. What would the if statement be to accomplish this. Im guessing for even it would be something like if(number % 2!=0)? What about for odd?

Write a menu driven program that will fill grid with values between 1 and 100. Begin the program by declaring a array of type int. Then present the user with the following menu
Enter 1 to add
Enter 2 to edit
Enter 3 to delete
Enter 4 to search
Enter 5 to display
Enter 0 to Quit
Each item of the menu must be implemented as a function. The program should Only allow values between 1 and 100
Always ask the user to apply coordinates for the cell to be changed
Flag an error when try to delete or edit a cell with a zero (0)
Flag an error when try to add to a cell that is not blank
Display the complete and nicely formatted grid when option 5 is selected

I installed FLTK 1.3.X (from here [URL] ...) on my visual studio 2012 compiler and use PPP book for programming (this: [URL] ..... ). My problem is about filling a Shape in. For example , this code:
#include <Simple_window.h>
using namespace Graph_lib;
int main() {
Simple_window win(Point(100,100), 1000, 600, "Binary_tree");
Graph_lib::Circle c(Point(200,200),50);
c.set_color(Color::red);
[Code] ....
When I run the program, All three Shapes are drawn but only the Rectangle is filled in! Why?
set_color works for the three and apparently the set_fill_color is defined for all Shapes and it too should work but why it doesn't work for Circle and Ellipse?
This is the .CPP and .h files [URL] ....

I'm working on a personal project, where I have a database (SQLite) and a dataGridView. Now This is what I have:
public Form1() {
DataSet ds = new DataSet();
SqlConnection connection = new SqlConnection(@"Data Source=testingsql2.s3db");
SqlDataAdapter SQLda = new SqlDataAdapter("Select * from User", connection);
SqlCommandBuilder SQLcb = new SqlCommandBuilder(SQLda);
dataGridView1.Fill(ds, "User"); //Error here
dataGridView1.DataSource = ds;
dataGridView1.DataMember = "User";
}
I've marked where I get the error.
And the Error description:
Error 1 'System.Windows.Forms.DataGridView' does not contain a definition for 'Fill' and no extension method
'Fill' accepting a first argument of type 'System.Windows.Forms.DataGridView' could be found
(are you missing a using directive or an assembly reference?)

I am new to c++ and have started creating a dummy program to perform a simple task of writing a few strings to the console, which are first generated using random generation. When I execute the code, an extra line for each generated object appears in the console.
int gemNum;
cout << "This program calculates the value and type of gems
";
cout << "Please enter the number of gems: ";
cin >> gemNum;
vector<int> gemVector(gemNum);
vector<int> gemCollection = fillGemCollection(gemNum);
vector<int> gemSort = sortGems(gemCollection);
vector<string> gemResult = finalGemValue(gemNum, gemSort);
for(int i = 0; i<gemResult.size();i++){
string gemString = gemResult[i];
cout << gemString << endl;
}
This program calculates the value and type of gems..Please enter the number of gems: 4
10 hematite
40 carnelian
60 onyx
120 silver pearl
Press "e" and enter to end program

Obviously I'm trying to grasp C programming and am very new. I don't understand why this isn't working, and i think its more than my lack of knowledge of C syntax. I believe the correct memory is allocated but when examined with gdb i don't find what i expect....

I'm in need of an algorithm to find the points within a triangle(vertices are known. 3d coordinates). The points are to be at same distance from one another i.e. the points are uniformly distributed within the triangle.
I have done a search about the topic and have come across some ideas like lattice points generation ,tiling polygons with Lattice triangles [URL] .... and taking their centroids as the points.

This code is for a member function called Triangle. It's a Draw() function that uses border characters and fill characters. I've been trying to work it out in a seperate file just so I can get it to work before I add it to my function definition.
#include <iostream>
using namespace std;
int main() {
for(int i=1; i<=8; i++) {
for(int sp=1; sp<=8-i; sp++) {
[code]....
I haven't attempted the fill characters (well... I have, but it was so wrong it was ridiculous). I need to get rid of the extra '*' at the very top. Here's an example of what this should look like...
*
*#*
*###*
*#####*
*#######*
*#########*
*###########*
* * * * * * * *
