why my application actually crashes after it compute the area of a cross.
I output is correct but it crashes after it calculation is done.
cross.cpp
void Cross::setCrossCord()

for (int i=0; i<=12; i++)

The results of my code is supposed to be very simple: return the 2 integers and then their sum. However, it's doing returning the first value, then an address in memory(rather than the 2nd value), and then the 2nd value(rather than the sum). Here is the code:
#include <stdio.h>
#include <stdlib.h>
struct calculator{
double num1;
double num2;
double result;

I want to print the output of a c programme to a printer. Operating system is MS Windows xp sp2. This is the programme:
Code:
#include<stdio.h>
#include<conio.h>
void main()
{
printf("
Hello Chandan2... ");
getch();
}
The output "Hello Chandan2..." is to be printed in printer, when i run the programme , but how to do it?
When you have constant arrays, they are stored in the programme memory space. Upon execution, they are copied into the data space for easy access. To save space in the data space, it is possible to stop it from being copied. Some compilers will deal with this by just specifying the array as const, g++ has a type modifier called PROGMEM.
In any case, the problem is that I'd like to generate some data, preferably without using an external programme to do it. Hence, my question using the template system. Now I could possibly use macro metaprogramming via boost instead of template metaprogramming, and I may have to go that route. However there are limitations, especially since its numbering system is only equivalent to an unsigned byte, which I possibly could use, but could become more messy than if I use the template system that has long long types as well as a whole slue of type safety mechanisms.
cause I cant find why it crashes. It compiles without any error,but crushes when i run it and I can't find where is wrong the code.
Code:
#include <stdio.h>
#include <time.h>

This has happened before, when I try to run a code it will say "blah.exe has stopped working" and I would have to change the code in some way to make it work.

Purpose of program: Every 2 lines of the input file belong to 1 participant. The line with decimals include times a person has run miles. While the second line of each participant are integers that indicate the best sets from workouts the participant had done.
so an example of the output

Worst Time:
Average Time:
Weight Workouts:
Most Sets:
Least Sets:
Average Sets:
Participant #2

I have the text parser done, but when I use it, the program crashes. Just because of how I test my code, I know the section where it occurs, but I'm not sure what the exact problem is ( no errors or warning, so it's just something I don't see ). Here is the full code

#include <stdlib.h>
#include <string.h>
#include <ctype.h>

I probably made a mistake in the way I allocated memory or tested values, but I'm not sure where it is in my code. Currently it just prints out "Failed to parse data on line 1" then crashes. Here is the text file I give to this program.

So I've been working on a sorted linked list homework assessment and I've been stuck on a problem for a while now. Below is my code for inserting a new object into the linked list, for some reason it keeps crashing whenever I try to malloc temp. (between the "checkpoint" and "after malloc" printf statements) .
Code:
int SLInsert(SortedListPtr list, void *newObj){
SortedListPtr curr = list;
SortedListPtr temp = NULL;
if(list->obj == NULL) /*if the list is empty insert obj into the first node*/ {
list->obj = newObj;
free(temp);

I randomly get this when I execute my program. Sometimes it happens three times in a row sometimes it can go about 10 times before it shows up again.
I was not able to find out what the error code means, and I can't pinpoint the error. During debugging it NEVER happens, and logging tells me it happens between two cout << operations.
what the error code means?
#include <iostream>
#include <string>
#include <limits> //for std: numeric limits
#include <algorithm>
//Function to get an integer from the user that is greater than or equal to zero.
int getPositiveIntFromUser(const std::string& prompt) {
int retVal = -1;

The first part works, but it doesn't calculate the GCD or LCM at all, it just crashes!
I having some issues with two different programs here... One of them crashes and returns random negative numbers whenever it reaches a "fscanf" function and the other displays a "Polink fatal error: access denied" error.

I thought the reason this kept crashing before was because I didn't type the data into the text file it was writing too correctly, but I made another program to do that, and it crashed whenever it got to fprintf. Program works perfect besides the file stuff...
code:
/part of main function
int *A=NULL;
//load from file
load_from_file(A, &next);
printf("next=%d
",next);
getchar();
printf("A[%d]=%d
",0,A[0]);getchar();//here program crashes
}

I initialize array A with NULL in main, and I "load" it with elements from a file. The code without function is working. But when I tried to use a function as above, my array crashes!!!
Why program crashes when reading linked List from file?

#include <fstream>

So, I have this code:
...
MakeTexture((char*)ilGetData(), ilGetInteger(IL_IMAGE_WIDTH), ilGetInteger(IL_IMAGE_HEIGHT));
...
And it compiles fine and, supposedly, works fine too, but when I try to put a break point inside the MakeTexture fuction gdb just goes crazy, it freezes and starts alocating memory until it reaches like 30+ mbs, and after that codeblocks freezes and I have to terminate the gdb process to return everything back to normal.
Now, another weird thing is that this only happens if I pass (char*)ilGetData(), if I pass something like NULL to the function, this doesn't happen.
Oh, also, the MakeTexture function is this:
int MakeTexture(char *pxData, unsigned w, unsigned h)
{
return 0;
}
Implementation of a simple binary tree. What I'm trying
#include <iostream>
using namespace std;
struct bintree {
int number ;
char letter ;
bintree *left = NULL ;
bintree *right = NULL ;

It crashes when I try to print, I dont think it is inserting the last values into the tree and so when it trys to print a null value it crashes. I'm just curious if I'm heading in the right direction and perhaps how to fix my printing issue as well as some hints on deleting and searching.
I've got the following code which demonstrates a problem :
Code:
struct A {
double x[2];
double i;

struct B : virtual public A {

I'm wondering if this is a compiler bug. Why doesn't the pointer-to-(derived)-member work for the array if it works for the non-array?
I have written a MFC dll to interact with an API and it is run by the target program. the first 100 bars are drawn properly but then the program ceases to operate. I am guessing I have a memory leak but I probably just dont understand what I am doing as I am quite new to programming MFC GDI. Here is my code that causes the trouble...
The variables coming in are commented out to facilitate testing and so it would be displaying the same bars over and over because of this. it worrks for 100 bars, then crashes.
void MainDlg::SS_UpdateChart() {
// the chart plot is completely recalculated each time a new bar is shown
// 300 is plottable height
// 400 is plottable width, 39 bars
int displayChartHeight = 300;

My assignment is to write a system for managing a radio station. The code is composed of four classes:
Song: each song has a name, a composer and a singer, and has a few segments: INTRO,VERSE,CHORUS,TRANSITION, while each represents a different length string of chars.
Playlist: a multiset of songs, and a pointer to a RadioStatistics instance (see below).
RadioStation: a set of Songs (will represent the station database), and a list of Playlists, each playlist holds a few songs from the database.
RadioStatistics: can only be instantiate once, this object gather statistics; it has two maps: one that counts how many times a song was played, and second that counts how many times each singer was played. (the key is the song/singer name, and the value is the counter).
The RadioStation has a constant that defines a limit to how many times a song is allowed to be played. whenever a song reaches this limit (meaning, it was played too much), the program needs to skip to the next song in the database.
so, I run this test from main, and the program crashes (or more accuratly get stuck, since the console stays open and the program keeps working until I stop it).
I made a few changes and run the debugger a few times, and was able to focus on the problem.
Song.h:
Code:
#ifndef SONG_H_
#define SONG_H_
#include<iostream>
#include<string>
[Code] ....
I ran a step by step debugger, and found out the problem lays with line 90 in RadioManager.cpp, when the while loop runs its fourth iteration. It crashes when it tries to dereference the iterator, while it points to the fourth playlist in the list.
And here's some more weird stuff: when I comment out line 73 in main.cpp - it works perfectly fine! (line 73 in particular! commenting out any other line in main.cpp didn't worked around the bug!)
