I have a local student and international student class inherit from student class. read and print are virtual functions. After i have set all the member variables when i wan to print out all the student information, my program crashes.
Code: int main()

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 ;
[Code] ....
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.
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>
#include <math.h>

In my program, I am trying to implement a set in which I can add/remove and print, it doesn't have to be a specific value removed just that it removes an item from the list. When I call the removeItem function it crashes, saying my iterator is out of range. I don't understand what is wrong. Here is my code:
#include "stdafx.h"
#include <iostream>
#include <set>

Problem: When I add a new variable to complete my program, it crashes. I have tried tracing where the problem is but it leads to adding new variables
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
Participant #1
Cardio Workouts:
Best Time:
Worst Time:
Average Time:
Weight Workouts:
Most Sets:
Least Sets:
Average Sets:
Participant #2
...
Why my program is crashing
#include <stdio.h>
int main () {
// Stats Col0=BestTime Col1=WorstTime col2=mostSets col3=leastSets Col4=Average_time Col5=Average_sets
float chart[20][12], stats[10][6], best_time=100, worst_time=0, most_sets=0, least_sets=100, avg_time, avg_sets, sum;

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
Code: #include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <ctype.h>
#include <math.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.

rest 1000

I'm trying to code a Singly-Linked List(Double Pointers) selection sort program and I can't tell what the problem is. My compiler says no errors but when I run the program, it crashes right after I enter the values.

i wrote a little program with fseek. It works good till it reaches the first fseek(). Then it crashes and stops responding.My code:
ifstream inp("myfile.txt");
if(!inp.is_open()) return false;
inp.close();
FILE *f;
fopen("myfile.txt","rb");

int main() {
int vnum = 0;
VEHICLE *vehiptr;
VEHICLE *dptr;
cout<<"Please enter the number of vehicle: ";
cin>>vnum;
vehiptr = new VEHICLE[vnum];

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.
Code:
/* Evan Wentz */
/* Pike - ET2560 */
#include <stdio.h>
#define MAX_ACCTS 100
int accounts [];
double balances [];

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...

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;

How to add data to slVect ?

I need debugging the code provided below, which reads data from a file and puts it into several vectors.
Something very strange happens: if I try to read the file up to the last line, I get an runtime error, while if I try to read the file up to the second last line, I do not get the error.
However, if I try to read the file up to the last line, it READS IT CORRECTLY, as you can see that it prints out the right values.
Following there is the code and the file that I am trying to read.
Code:
#include<stdio.h>
#include<iostream>
#include<fstream>
#include<vector>
#include<set>
#include<queue>
#include<cmath>
int main() {
std::ifstream fp;

Following, there is the file "link1.dat" that I am trying to open.

I'm trying to read information from a file and put the data into vectors of its appropriate type. For example: the file will have an int ID, string firstname, string lastname, double salary, int hours_per_week, and string work_position. All this data is separated by ";". I don't know how to read this file into the appropriate vectors: vector<int> ID, vector<string> fname, vector<string> lname, vector<double> salary, vector<int> hpw, vector<string> work.
View 8 Replies View RelatedI have a file with data in it, and I'm trying to print that data, but it is:
1) not reading the last file (record #83)
2) it's printing out the last record twice (in this case, #77)
//record data for each tool
int recordNumber;
string toolName;
int quantity;
[Code]....
here is the printData() function
void Hardware::printData(int _recordNumber, string _toolName, int _quantity, double _cost)
{
cout << left << setw(10) << getRecordNumber() << setw(20) << getToolName()
<< setw(10) << getQuantity() << right << setw(10) << fixed << setprecision(2) << getCost() << endl;

Let's say we have entities like lines and circles. And each entity can have a pen attached. And a pen is a color and line width. All entities needs to be manipulated through a operations interface. All entities added to the program needs to be added through using a factory pattern.
So we end up something like (pseudo code)
class Line // for immutable objects {
..
..
} class MutableLine extends Line //for mutable lines {
} MutableLine line=factory->newLine(20,20,50,50); // Create a new line entity
[code]....
So, essentially I want no code to be able to operate directory on entities, unless during creation of the object (color, layer, line width etc...) so I am planning to create Mutable versions of all entities besides the immutable versions.
When requested for selected entities or all entities, I am planning to return a list of immutable objects and in fact I am planning to return a new copy so it's not possible to operate on anything directly.
The reason is that I am planning to create different storage backends swell, so I can operate on entities in a database, or shared memory... stuff like that. At least to hide the internals and provide a stable API.
My questions are:
How can I make sure that people don't do 'tricks' casts for example to a mutable version to change objects directly?
So, if I'm right, computer store their data as binary values. So if I write int x = 5; , my computer converts the value of x from decimal (5) into binary (101) and stores it in memory as a a binary number. If I print that value on the screen that value is converted(by default) back into a decimal number before being printed on the screen.
Now, my question is if there is any way to print the value of x directly into binary(as it's stored in memory) without it being converted back into a decimal value?
I create a list of vectors (a vector of n vectors of m elements).
std::vector <std::vector <int> > vsFA (n, std::vector<int>(n));
How I assign values? I try below, but not worked
void armazenaFA( std::vector <int> &vFA) // this function only knows about vFA
{ vsFA[n] [m]= simTime().dbl();
OR
vsFA[n].push_back(simTime().dbl());
}
