I'm getting Unhandled exception when try to run option 3.
This my code below.
Code:
#include <iostream>
#include <string>
using namespace std;
struct Vet {
string name;
int numOfAnimals;
string phoneNum;
[code]....
I have been assigned to create a search function in text file, but I received this error when I run the program and try to search: Error message: Unhandled exception at 0x0f85d442 (msvcr100d.dll) in Ticket.exe: 0xC0000005: Access violation reading location 0xcccccd08.
I don't know what is the exactly problem. So I just copy everything and paste here. Please don't fear of these codes, I have 2 files only, but I will paste 3 files here, the one is prototypes.h, then the main.cpp, the last one is part of my function that can working well alone, but when I put them into main.cpp I will get the error message like I mentioned before.
#include <iostream>
#include <fstream>
#include <string>
#include <locale>
#include <vector>
#include <algorithm>

I can't even make a guess what could be the problem here. I think it is easier tho show a video:
I think it describes my problem. I don't know what's my mistake! The debugger doesn't really work, I don't use malloc or free.
I'm trying to run this program, but at one point it crashes and gives me the following error:
Code:
#include <iostream>
#include <cstdlib>
#include <ctime>
#include <string>
#include<conio.h>
using namespace std;
const int maxtries=5;

I just started on a project on c++ and I was wondering if it is possible to add a select option (where the c++ program requires the user to select an option) . I couldn't find this anywhere.
View 3 Replies View RelatedI've been having problems with my loop that asks if the user wishes to continue or not. The required input should either be 'y' or 'Y', or 'n' or 'N'. Anything else should be counted as invalid, and repeat the prompt for input. The first few times I ran my program, the compiler does not read it as a loop. The next few times just won't work properly.
Here is the prompt:
Code:
void question() {
char option;
printf("
Do you want to continue? {Y|N) ");
scanf("%c", &option);
[Code] ......
As it is, it immediately runs the else option, but otherwise runs just fine. I suspect it could be because I have not specified a size for the option variable, but I try doing that, and the prompt relegates everything to the else.
(And also, here's the rest of the code. Basically, it just assigns a value to the letters of the word (a/A = 1, b/B = 2, etc.), adds these values, and determines if a word is prime or not based on the sum.)
Code:
#include <stdio.h>
#include <string.h>
#define size 30
int main() {
char letter, word[size], lower, upper, option;
int i, value, ans = 0, a, choice = 1;
[Code] .....
I have a menu for a project that takes a string input and does whatever option you specify. It works perfectly EXCEPT when it goes through the while-loop (while you didn't say quit the menu reloads). It will spew out all the text in the menu like a bulimic teenager. Then it reloads properly and asks you for an input like nothing happened. While this is not a fatal error (code still functions)...
Code:
#include <stdio.h>
#include <math.h>
#include <string.h>
double aa=0, ab=0, ac=0, sa=0, sb=0, sc=0;
char a1[13], o1[]="AAS
[Code] .....
i need one more option which it can display all the items i have entered in alphabetic order in my program..this is my coding......
#include<stdio.h>
#include<string.h>
#include<ctype.h>
#define capacity 1000
void cal_item(struct item[capacity]);
void input(struct item[capacity]);
}

So , i had to make an rock paper scissors game . After lot of hard work and struggle ,I completed it but my professor rejected it since I didnot add option where it says "Would you like to play again .Y/N " . The code has too many brackets ! Here is my code
#include <iostream>
#include <ctime>
#include <cstdlib>
using namespace std;
// for displaying the outputs to the user; passing string to functions
void user_win() {
[Code] ....
Remove the break statements from each of the cases. What is the effect on the execution of the program?
Add an additional switch statement that allows for a Passing option for a grade of D or better. Use the sample run given below to model your output.
Sample Run: What grade did you earn in Programming I ? A YOU PASSED! an A - excellent work!
Rewrite the program LastFirst_lab44.cpp using if and else if statements rather than a switch statement. Did you use a trailing else in your new version? If so, what did it correspond to in the original program with the switch statement?
// This program illustrates the use of the Switch statement.
// The break statement causes all subsequent expressions to be executed as well, also known as "falling through".
// The trailing else statement acts just like the default section if none of the options from before work it gets "defaulted" to it.
#include <iostream>
using namespace std;
int main() {
char grade;
cout << "What grade did you earn in Programming I ?" << endl;
[code]....
how do you add an additional switch statement? i tried multiple times and i'm not sure if i don't understand braces enough but it didnt seem doable. also, I'm not sure what the teacher wants me to submit.
I need to do a code that gave me Original string, uppercase string, lowercase string, reverse string (if letter is upper then convert to lower, and if lower then convert it to upper) and uppercase first (first character of each word in uppercase).
I need to do it in functions but i dont know hot to use strings. The program should provide the option to save the outputs in a file.
Code: Obj<TCHAR>* obj = dynamic_cast<Obj<TCHAR>* >(I->objects[0]);
Which is resulting in this error
Code: A dynamic cast is present, but the correct RTTI option is not specified.
I am running ubuntu and have tried adding -1GL to the end of my gcc compiling commands but the error says "unrecognized commandline option: 1GL". do i have to install any packages to get this to work?
Its supposed to be an l not a 1.
Basically i have a 'HomeWindow' with a button 'OptionWindow'. My idea is that the 'OptionWindow' button will open up the 'OptionWindow'. Which will give the user three options 'Option1', 'Option2' and 'Option3'. If they pick 'Option1' then in the 'HomeWindow' in a stackpanel i want it to display 'UserControl1'. Where as if they pick 'Option2' then in the 'HomeWindow' in a stackpanel i want it to display 'UserControl2'.
If you need some of my code that i have already then let me know what you need as i have a lot of it so can't paste it all in one go. But the new thing i need is the way of making the user-controls in the 'HomeWindow' change depending on what is selected in the 'OptionWindow'.
today I've been working on a rock, paper and scissors game. It compiles OK, except:
It doesn't use a random number from 1 -3, or goes out of scope.2. It doesn't COUT and it doesn't flush the buffer.3.
My code is as follows:
#include <windows.h>
#include <iostream>
#include <cstdlib>
#include <ctime>
std::string randomPC(int &);
void PCSelect(int &);

I'm creating a program that is based on a menu system. Basically each menu is its own user-defined function. The problem is at each menu you can input 'b' to go to the previous menu. I just have it call the function of that menu.
However, do the functions need to complete themselves eventually? If I just keep calling functions will I just keep going further and further deeper into ever running functions?
If so how do I avoid this and yet keep the option to go back to a previous menu/function?
My perceptron's train function seems to materialize my BadInput exception object out of nowhere. Yet, everything works fine.
And when I put an forever loop in main to validate the output with many different inputs, I get a bad_alloc exception and a call to terminate().
BadInput.hpp
Code:
#ifndef BADINPUT_HPP
#define BADINPUT_HPP
class BadInput {
public:
BadInput(int val):difference(val) {
[Code] ....
I cannot figure out why train() is throwing an exception...feedforward didn't, as it's error message never printed.
I catch an exception and want to log it on the console. This works as exepcted, but Valgrind shows me a set of invalid reads.
Here the code of the catch-block:
} catch(HGL::IOException &e) {
logError(e);
}
The signature of the logDebug is: BasicLogger &operator<<(const std::exception &e);
Now valgrind shows me 4 errors like that:
==20943== Invalid read of size 1
==20943== at 0x402C658: strlen (in /usr/lib/valgrind/vgpreload_memcheck-x86-linux.so)
==20943== by 0x41554DD: std::basic_ostream<wchar_t, std::char_traits<wchar_t> >& std::operator<< <wchar_t, std::char_traits<wchar_t> >(std::basic_ostream<wchar_t, std::char_traits<wchar_t> >&, char const*) (in /usr/lib/i386-linux-gnu/libstdc++.so.6.0.16)
[Code] .....
Generally I dislike invalid read in my code, even if they are harmless like in that case.
If I don't pass a reference, but a copy of the exception, I don't get this invalid reads, but also loose all information, because of the implicit upcasting.
Why I get the illegal read, resp. why std::wstring is deleting it on the way to the <<-operator?
I know how exception handling works, but how should I actually use it in action? Let's say I have something like this:
Class X
{
public:
X();
//Pre-condition: example can't be 3.
void number(int example);
[code]......
If I know that the exception can only happen at the beginning of the function, is it okay to catch it right away?
I'm trying to do some operator overloading, the function is supposed to add the values at index [i] of two vectors and place the result in the returning vector. The problem is I keep getting a vector out of range. This is the overloaded operator I'm working with (relatively new to these):
vector<float> operator+(const vector<float>& a, const vector<float>& b){
unsigned long size;
vector<float> temp;
if(a.size() >= b.size())
size = a.size();
[Code] .....
and then I would do something like this in the main:
vector<float> v, v1, v2;
v1.push_back(9.1);
...
v2.push_back(8);
...
v = v1 + v2;
but when I try to output the vector v I just get a vector out of range exception.
I'm making an "improved" array for my programing class. It's currently unfinished, so you might see some commented out code. I'm trying to debug what I have.
I keep getting these errors when I try to complile my main.cpp:

write a program as described below: program that reads in two integers (age, social security number). You should write functions that throw an out-of-range exception forage (no negative numbers)SSN (must be a 9-digit integer) My code is written below:

int main(){
int age = 0;
int ssn = 0;

If a class A contains an array of objects of another class B.. And in the constructor of A, while constructing objects of B, any one object throws an exception, then how can we guarantee to release all the memory acquired.. so that there is no memory leak..
class B{};
class A{
public:
B Array[100];
...
};
In the above code, if in constructor of A, suppose 99 objects of B are constructed successfully, but 100th object throws exception, then how can we guarantee to release all the memory acquired by the other 99 objects?
I have one problem deleting a file with boost. The file is opened in another application and cannot be deleted. I am supposed to received an exception error but I don't get it.
Here is my piece of code, very simple:
bool delete_file(const string &path) {
boost::filesystem::path bpath(path);
try {
if (boost::filesystem::remove(bath)) return true;
[Code] ....
I have put a breakpoint inside the catch part but it does not come to this point. Instead, the the output window of visual studio, I got these lines:
First-chance exception at 0x00007FFD2E575A88 in site_server.exe: Microsoft C++ exception: boost::filesystem::filesystem_error at memory location 0x00000070F8E3E920.
Unhandled exception at at 0x00007FFD2E575A88 in site_server.exe: Microsoft C++ exception: boost::filesystem::filesystem_error at memory location 0x00000070F8E3E920.
How to manage this situation?
It is advisable not to throw the exception from destructor. Because if exception happens stack unwinding happens. suppose the destructor again throws the exception then on part of first exception again one exception is thrown and exceptions can not be handled at same time. This is what i read from stack over flow.
