I made this as a simple do/while program, and if i run it, the second do/while statement will keep on going forever, without the [cin >> bored;] line working?
I just dont see what the issue is here. I have stared at this thing forever. Im trying to make a calendar from scratch so I can be prepared for my second test on Friday.
Code:
#include<stdio.h>
#include<stdlib.h>
int main(void)

int i, n, s;

I've implemented it a bit differently: I create 2 temporary arrays, one for the numbers lower from the pivot , an done for numbers greater then the pivot. in the end of each iteration the 2 arrays are copied to the original array:
Code: #include <iostream>
void QuickSort (int* A , int start, int end){
if (end-start<3){
return;
}
int mid=(start+end)/2;
int pivot=A[mid];
int lA[end-start] , rA[end-start], rCounter=0,lCounter=0;
int curr=0,i=start;

I am trying to release my C++ app to run on desktops that dont have VS installed and have created an install shield app to install on the desired computer. my issue is even after packaging it, it still requires certain DLL's...I read online that I had to copy 'msvcr120.dll' and a few others to syswow64 and sys32 folders but now when I try run my app it just crashes before starting.
I think it sucks that Microsoft no longer packages required DLL's like it used to in 2010.

i'm right now using C, IO is done via ncurses, but that won't affect the following problem, i think. The relevant code is:
#define SIDEBARWIDTH 27
//...
typedef struct {
[Code]...
surprisingly this works, now the new 3rd outputline is correct again. So it seems that the printcommand has some troubles with accessing the struct here. Not sure if that might be ncurses fault. Still feels odd.
Code:
#include <iostream>
using namespace std;
int main () {
char character = 'a';
[Code] .....
the point of this code is to increase character by 1 (so from a to b in this case).
The line highligted in red is the line that the system is rejecting at the moment (but there may be other issues). why it is invalid?
I should reduce the number of bitmaps I used in my code. I translated my particle engine into code that could be compiled as plain standard C
Currently, the code has a segmentation fault somewhere that I can't figure out. How it should function is that it takes orders from a queue for new lasers to store the instances in a linked list. It then takes that data and updates its coordinates, one node at a time. The first node should also be the first node to complete its life, so it gets removed, and the list is set to the next node in memory. If there are no more nodes left, a if-statement should catch it and either break the current loop, or wait for more items to be requested. If there are nodes left, the process will continue to remove the first node in the list until there are none left. Obviously this is not quite how it works. When I tested in once in SDL, the laser would update every 5 frames, but wasn't shown constantly, and would crash after the node was to be disposed of. When I initialize with the SDL parachute, it would exit before I event saw the screen. Also, the code I translated to standard C will display that the laser has been updated to the screen, but it never says that it has moved up. It crashes after about 4 printf() statments execute. My debugger has been giving me mixed SIGTRAPS, and "nothing is wrong" output. Here is the code in standard C:
Code:
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
#define MAX_LASER_QUEUE 10

Im about to program a RPG and, of course, the player has got an inventory. The items in this inventory are stored in a linked list and have IDs in form of strings.
player.cpp: (just the most relevant)
#include <list>
#include <string>
using namespace std;
[Code] ....
Of course, when the player saves the game, the inventory has to be saved too.
game.cpp(just the m. R.)
#include <fstream>
using namespace std;
class CGame{
[Code] .....
Now, in my code I write the linked list into the file savegames.sav
void CGame::save(CPlayer* player){
m_out.open("savegames.sav", ios::out);
m_out.write((char* ) &player->m_inventory, sizeof(player->m_inventory));
m_out.close();
}
In another function i load the list:
void CGame::load(CPlayer* player){
m_in.open("savegames.sav", ios::in);
m_in.read((char* ) player->m_inventory, sizeof(player->m_inventory));
m_in.read();
}
And when i access the loaded linked list with the .empty() function or so, Windows says the following:
<Mygame.exe> funktioniert nicht mehr (in English: doesnt run anymore).
I tried so much to fix that but i dint reach my aim.
I realized a Matrix class to practice and I have a problem I can not solve! Here my problematic code:

Mtrx.C
[Code] ...
And here the relative main section:
Code:
Mtrx rand1 ( 5, 5, bool);// ok
cout<<rand1<<endl;
Mtrx rand2 ( 7, 3, bool, -5, 20);// ok
cout<<rand2<<endl;
Mtrx rand3 ( 7, 7, bool, 0., 15.);// compilation error: undefined reference to
// "Mtrx::Mtrx<double>(unsigned long, unsigned, bool, double, double)"
// collect2: error: ld returned 1 exit status

I installed FLTK 1.3.X from [URL] on my visual studio 2012 compiler and use PPP book for C++ programming [URL]. My problem is about filling a Shape in.
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 on window 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 for Circle and Ellipse?

The program i am trying to make is for practice of using switch. the idea is the user enters a number and the program will print a day of the week corresponding to said number.
the statement is not complete with all cases yet, but i dont want to write all of it until i am sure of it being correct.
errors when compiling (gcc) are as follows
1 warning and 3 errors generated.

From the page: [URL] ....
#include <iostream>
using namespace std;
int n;
int& test();
[Code] ....
Explanation
In program above, the return type of function test() is int&. Hence this function returns by reference. The return statement is return n; but unlike return by value. This statement doesn't return value of n, instead it returns variable n itself.
Then the variable n is assigned to the left side of code test() = 5; and value of n is displayed.
I don't quite understand the bold sentence. Shouldn't value of n and variable n be the same?

I am writing a program that expands array list whenever they get too full...so far i have this:
Code:
#define DEFAULT 10
typedef struct ArrayList {
//array of strings
char **array;
[code]....
So, ArrayList *myList should return a pointer to the new arraylist or null if malloc fails. what exactly I need to set my maximum to, I know that it shouldn't be 0 and array[i] doesn't seem to be working either. I also am not sure if I am properly setting up null correctly for my array.
I just wanna have a very simple function that reads values from a text file row by row. The first value is passed along from the stringstream to my float data[] but after that it doesn't pass along anything. The strange part (for me at least) is that the stringstream contains the values it should contain, but they doesn't wanna end up in data[].
main.cpp
#include <fstream>
#include <iostream>
#include <string>
#include <sstream>
[Code]....
This code runs. However, when I run it, the text from printf doesn't appear until after I type in the two numbers.
I use Wascana, will it run correctly on other compilers?
Code:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int main() {
fflush(stdout);

I'm trying to build a new project and i installed some new libraries in it but when i try to compile any code it doesn't give me any value just press any key to continue, i didn't make any files but one and even if i tried to do this simple task it doesn't cout any result:
#include<iostream>
using namespace std;
int main() {
cout <<("ha");
system("pause");
return 0;
}
I wrote a program which was supposed to decrypt a file encrypted with the XECryption algorithm. Now, I know the decryption algorithm, but I have a problem with my ifstream object. It doesn't read anything at all, and the ofstream object just outputs a single random byte in a never ending loop. I've tried using cin, which works correctly, but it's not what I want.
Here's the code:
#include <fstream>
#include <iostream>
using namespace std;
int main() {
ifstream in("file.in", ios::in);
if (!in.is_open())

I am trying to change the value of of time in my vector of structs. The result should output 1430 as the value of shares[1].time though I get something different.
unsigned convTime = 1430;
std::stringstream out;
out << convTime;
shares[1].time = out.str();
std::cout << shares[1].time;
But my shares[1].time stays as its original value and not 1430.
I can't seem to get my program to alphabetize a vector string. It displays the names, but not in a sorted order.

size = nameList.size();

While working on another issue I started memory cleaning and refactoring. While refactoring I decided to create an array Resize Array Reize and Null Count:

for(int x =0; x<= Original.GetUpperBound(0);x++) {
if (Original[x,0]==null )
{returnInt++;}
