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'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 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;
[Code]....
#include <iostream>
#include <string>
using namespace std ;
int main() {
string bored ;
do {
cout << " program" <<endl ;
[Code] .....
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 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.
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:

cout<<rand1<<endl;
Mtrx rand2 ( 7, 3, bool, -5, 20);// ok
cout<<rand2<<endl;

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?

Overview: I'm creating a code to simulate quantum tunneling current.
I'm getting the code to output data on a spreadsheet file, and it all works except the following part, which are just giving values of 0 all the way down for the entire column.
j_tl=((eV*hbar*k)/(m/c*c))*(1 - R_lr - T_rl);
When I remove the ((eV*hbar*k)/(m/c*c)) part of it, it gives out values for the (1 - R_lr - T_rl) so I presume the problem is in the former. But I'm struggling to think what it could be. The same is happening for j_tr.

My coin/money change code works when there can be an exact change each time, i.e. when the 1 cent option is available. However, when the change options are only $10, $5, $1, 25 cents and 10 cents, it does not give me what I want for instance, I wanted to get change for $237.80, I was expecting to get:
23 10's, one 5, two 1's and 8 dimes. However, the code below is giving me 23 10's, one 5, two 1's and 3 quarters (there is no option left for the 5 remaining cents).how to fix it?
Code:
#include<iostream>
#include<algorithm>
#include<vector>

void change(double cents, int a[]);

I've tried a bunch of alternative methods to prevent an assertion error. "not understanding" the bug and why I'm getting it are relevant here, not proper, (or more appropriate), coding methods. I would write it in another way to prevent the error, I simply want to understand what is happening during run-time that causes the situation.What is the bug?

I want to increase the value of some elements of an array according to a certain condition. For example the following code:
array <int, 100> myArray = {};
myArray.fill(0);
for(int i=1; i<5; i++)
*(myArray.being()+1) ++;
I was hoping myArray[1] = 5. But it actually did not work. But if I code:
int myVar = 0;
for(int i=1; i<5; i++)
myVar ++;
Result: myVar = 5.
I had this question for a while - is it possbile (not intended, but if this "error" can occur) to actually increase AND decrease integer with ANY operation at the same time, so the result will be screwed integer? like this
int a = 0;
//some code
a++;
//meanwhile at the very same time, not the same code, so another thread or something
a -= 5
if it would go normally, the a would == -4, however is there any way that it will screw itself, and the "a" will be -5, or 1, or just will be somehow broken?
So, I've made programs like Prime number searchers and such. But the problem is if I use an int or long int variable for the program I am limited by the variable size. I can't search through numbers larger than their memory size. So my question is: Is there a way to allocate memory to a single variable, NOT AN ARRAY, so I can make a variable as many bytes as I want?
