My program works before i declare a new variable in class. Right after i declared a new int variable called prevans in my guess class, my program crashes when it runs.
Here's my code: Code: #include <iostream>
#include <time.h>
#include <cstring>
#include <cstdlib>
#include <vector>

I'm having a small problem on comparing a table i coded with a string that I want to input. I'm actually building a Bulls and Cows program and this is part of my assignment. What i want to do is to input a string and from the table get the results compared to the string i inputted.
Few words about the Bulls and Cows program.
The game involves two players, a coder and a cracker. The coder (either a person or a computer) chooses the four-digit number with all different digits and keeps it secret. The cracker tries to guess the secret number. After a guess, the coder gives you information about number of digits which were correctly guessed but in the wrong place (they are called 'cows') and how many are both the right digit and in the correct place (they are called 'bulls').
For example, if the coder chooses the secret number 0419 and the cracker guesses 6039, then the coder scores this as 1 cow, since 0 is a digit in the secret number that's in the wrong place, and 1 bull (9 is in the right place.)
what i want to do is when i input a string it scans the whole table of possibilities and gives me the results based on the string. so each row of my table is (let's say the secret code) and based on the given string(the guess) it gives me the result. Here's my table code:
Code:
void initialize(int poss[1296][4])
{
int i=0;
int j, k=0;
int m;

This problem is best explained by looking at its output below. I stored 15 different values but when retrieved some are wrong.
#include <iostream>
using namespace std;
class A {
public:
int ** pointer;
[Code] ....
I need to store and retrieve the 15 different values correctly. How to solve this? The main thing is, I need to store the pointer in class A objects.
I have an example where I have a variable belonging to a base class, but I would like to tell the compiler that it actually belongs to a derived class. How can I do this?
// base class: R0
// derived class: R1
// see function SetR1 for the problem
class R0 {
public:
int a;

I am trying to access a variable from another class through another class but it is not returning its "instance"?
Example:
Class View
Code:
...
V3D_Viewer viewer;
...
Class MainWindow
Code:
...
viewer* myView;
myView = new viewer();
...
Class Test
Code:
...
MainWindow window;
window.myView->setBackgroundColor(WHITE);

Linker error.
First off the error
Code:
Error1error LNK2019: unresolved external symbol "public: __thiscall ReachTop<class Character>::ReachTop<class Character>(class Character *)" (??0?$ReachTop@VCharacter@@@@QAE@PAVCharacter@@@Z) referenced in function "void __cdecl `dynamic initializer for 'gReachTop''(void)" (??__EgReachTop@@YAXXZ)Main.objDecisionTest
Reach Top class inherits from Goal Class
Goal Class
Code:
#ifndef _GOAL_H
#define _GOAL_H
#include "Action.h"
#include <list>
template <class T>
class Goal
[Code] ....
Code to create
Code:
Character* gCharacter = new Character(1, gWorld);
Goal<Character>* gReachTop = new ReachTop<Character>(gCharacter);
I can provide the character class and its inheritance aswell if you like.
I finished my project and it does work, but every time I hit enter to end the program I get an error that says my variable array is corrupted.
here is my code:
#include <iostream>
#include <ctime>
using namespace std;
int main() {
system ("color C");
[Code] ....
How could I stop this end error from occurring?
I have one problem with my code it's working until end of this program and program show this error: Run-Time check failure #2 - Stack around the variable 'Obsd" was corrupted.
here is a code, :
#include <iostream>
#include <conio.h>
using namespace std;
struct SData {
int SDSamples;
float SDSampleCount;
[code]....
#include <iostream>
#include <string>
struct WeatherStats {
double total_rainfall;
int high_temp;
int low_temp;
int avg_temp;
[Code] ....
When I run this program I am able to input data for the three months but after inputting everything I am prompted with a run time error that states: Run time check failure#3: The variable 'temp' is being used without being initialized. I've underlined the statement that the compiler says is causing this error, yet there is no variable 'temp' in that statement.
Computer are very specific right? So in the problem statement total_yearly_temp = total_yearly_temp + temp.avg_temp; there is a variable called total_yearly_temp and one called temp.avg_temp, but there are none called temp. It can't be complaining about the WeatherStats variable I defined in the first line of the function called temp because I did the exact same thing in the previous function and there are no errors concerning that.
I'm working through this neural network tutorial, unfortunately I get stuck trying to compile on line 28, saying "error: 'neuronNum' not declared in this scope." I seem to always get stuck on these kinds of errors, yet I don't understand because I though that the variable was declared and initialized within the for loop.

I tried changing the type of variable to char but i still get the same result. i also tried using a switch statement which was my first choice but i had the same issue.
Why I am getting this error
error: variable or field createBinaryFile declared void

If I DEFINE a global variable in two source files which belong to the same project, then there is a linker error "multiply defined symbols". But if I DEFINE a global variable in two source files which belong to the different projects, then it compiles fine. Why?

I need to have a program display an error message if the variable entered isn't an integer but then I want it to cin again. I have this but it doesn't work:
cout << "Enter an Integer: " ;
for (;;) {
cin >> var;
if (!cin) {

I am not sure how to do what I want and this doesn't work, it just repeats That wasn't an int.. over and over again.
I have an if statement that should either match a text variable that the user has entered and a another text variable that has been got from an array but they won't match even if they are the same,Im at a lost with it.
