making my delete function work. My program does compile but my delete function doesn't work. I haven't finished my last two functions because I am focusing on the delete but how to Sell a title and print the value of all sold titles would be nice as well.
I want to overload ostream& operator << so that it prints content of whatever container I want. I wrote something like this:
Code: #include <iostream> #include <list> #include <set> template <class T> ostream& operator << (ostream& strm, T l) { for (class T::iterator it = l.begin(); it != l.end();++it)
[Code] ...
It works. However, it'd be nice to actually have these spaces between numbers. There's the problem: when I uncomment the code (and remove ++it from the for loop), the compilers gives me a bunch of messages with the "main" reading:
Code: stl_test.cpp: In function "std::ostream& operator<<(std::ostream&, T)": stl_test.cpp:19: error: ambiguous overload for "operator<<" in "strm << " " "
Why does it not work? (it seems like << isn't overloaded for const char *, but simple cout << " "; works, so...)
We can't use the std::vector, std::map and std::lists implementations.
std::realloc doesn't call the destructor automatically.
If it is theoretically possible, we'll consider it and write lines similar to it, which should remain commented until something similar is possible.
int main(){ #define START 1000000000 #define END 10 unsigned int * array=new unsigned int[START]; delete[START-END]array;//Our suggestion to shrink the array delete[]array;//Delete the array return 0; }
struct b { char fullname[100]; char title[100]; bopname };
and i declare a pointer to the struct as follows
b* bp;
and at runtime,
bp = new b[5];
In the end, is the statement delete[ ] bp enough to release the dynamically allocated memory. Or do i need to separately delete bp[0],bp[1]...
Does delete[ ] bp indicate that the array[ ] pointed by bp has to be deleted?? [I am confused as to how this happens, since the pointer only points at the 1st struct address]
We're trying to overload the delete[] operator with specific arguments. Which is the right way to call it? We use the GNU compiler and obtain compiler errors with all of these samples:
#include<iostream> using namespace std; typedef unsigned int P;
How can I declare global 'delete' operation multiple times? Like, I've an implementation of global 'delete' operation in a file 'x' but I want a different behavior in file 'y'. However, if I override it again in file 'y' I get multiple definition error.
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:
I've implemented a records system for a college assignment and everything works as intended. However upon increasing the amount of records to store in my array above 10, the program crashes upon adding a new employee and I can't work out why...
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; int i, j; int p=0;
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() { clsUniversityProgram objProgram[3]; for (int x = 0; x < 3; x++)
My programs complies and runs. However, whenever i try to enter something when prompt to enter the number of accounts i wanted to create my program crashes.
By the way, im using codeblocks.
it says
terminated called after throwing an instance of 'std:: out of range'. what(): basic_string::substr"
Code: #include <iostream> #include "clsInterest.h" #include "clsDate.h" using namespace std;
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
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.
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.
#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...
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;
I'm a bit stuck on a program that prints out a 8x8 chessboard and Q to represent queens where the user enters input. The intended output is: Code: Enter the columns containing queens, in order by row: 0 3 4 0 0 7 6 7
