My program has a goto label in it and when the program is not instructed to goto the label, it does. When control goes to the line that it is on, even if no where does it say to execute the label's content, it does execute it.

I've been making an RPG in C++ and I've used goto all throughout the program. After receiving an error and Googling how to fix it, I read that you shouldn't use goto. What can I use as a instead of goto, which isn't 'considered bad programming practice'?

Or something along those lines?
I am new to c++ programming, and I wrote this program. It runs perfectly but the problem is I want the program to stop If I entered letters other than A,B or C
The code as follows:
#include <cstdlib>
#include <iostream>
#include <cstring>
#include <iomanip>
using namespace std ;
int main() {
// Deceleration Statements

I have a project where I have to schedule 3 doctors for 28 days. Doc A, B, and C. The rules are:
1. They can't work back to back, but only on weekends. Example Doc. A can't work Monday and Tuesday, If Doc. A works Saturday, he must work Sunday also.
2. Doc. A and B work alternate weekends.
3. Doc. C can't work Tuesday or weekends.
I'm trying to base my project off of the 8 Queens program that uses backtracking and the goto function. Right now, I'm just trying to get my program to print this
100100100
010010010
001001001
Here is my goto Code
#include "stdafx.h"
#include <iostream>
#include<iostream>
using namespace std;
void print();
#define n 28 //28 day schedule
int a[n]={};
[Code] ....
If you look at my code you will notice that it prints out like this, where array c doesn't take in account for array a.
1010101010101
0101010101010
1010101010101
I need getting the program to modify a[], b[], and c[] when necessary. I should be able to change any array element to '1' and it will automatically fill in the schedule by itself. example
010001000101001
100100101010010
001010010000100
It's a tic-tac-toe program. I haven't finished doing everything I need to for the project, I'm just trying to get certain parts working as I go.
Anyway, my problem: The program will print the board and ask the first player which square they want to mark. Then it will print the updated board, print the question for the second player to input their square choice but not actually stop to let the user enter anything. Instead it prints the board again and then prints the question for player one again -- this time stopping to let them type in their choice.
Here's my code:
#include <stdio.h>
// Function prototypes
void printBoard(char board[3][3]);
int main() {
int quit = 0;
// Loop so game continues until player quits
[Code] .....
And it looks like this when I run it, as an example:
-------------
| 1 | 2 | 3 |
-------------
| 4 | 5 | 6 |

| 7 | 8 | 9 |

Player 'C' enter a square: 5
-------------
| 1 | 2 | 3 |

| 4 | C | 6 |

| 7 | 8 | 9 |

Player 'U' enter a square:

| 1 | 2 | 3 |

So when you enter the number 99 its supposed to quit the program and it wasnt so i fixed that then i noticed that if you don't hit the green its supposed to loop back to a certain point but it was going to far back so i put a goto statement in and now it wont output my data table.
I am writing a program which creates a set of coordinates that when plotted will reveal a syastro crescent moon character. If you imagine plotting a crescent moon as two circles with different radius, where the overlap will create the shape. The problem I am having is how to just plot where they overlap ( ie the crescent moon part) and no the rest of the circles. How can I impose a boundary to stop the program creating coordinates I dont want. My first attempt is an if else loop.

I am stuck on my program right now, what i am trying to do is get the sum of the amount from a access database table and than display it on a label, however i cant seem to get this to happen. This is what I have so far:
OleDbConnection conn = new OleDbConnection();
conn.ConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=Church.accdb";
conn.Open();
Form1 frm1 = new Form1();
//frm1.Show();
//string tableName = frm1.tableName;
//string time = "4/5/1991";
string fullName = memberscmb.Text;

I'm trying to print numbers in a label but I'm not having success. For example, I have the following code:
private: System::Void txtLeftWheel_Click_1(System::Object^ sender, System::EventArgs^ e)
{
for (int i = 1; i <= 1000; i++)
{
Sleep(100);
this->lblLeftWheel->Text = (Int32::Parse(this->lblLeftWheel->Text) + i).ToString();
}
}
The idea is that when I click the button, the numbers on the label increment from 1 to 1000.
The Sleep() is there to slow down the loop and the user can see something happening. However, if I put the Sleep() before the label->, the form freezes completely. If I put the Sleep() after the label-> text, the form freezes for a few seconds and the label text goes from 1 and jumps straight to 1000.
The expected functionality is that the label displays numbers 1 through 1000 but increment every second.
I have a label on my main form. When I menu select my settings form, I make a change to the label text on the main form but the label text does not update with the new text.
So here is my code in my settings form:
MainForm frm = new MainForm();
frm.paintMainFormThemeTitle(logoText); // updates the main form label
I may not fully understand the new instantiate key word, but doesn't this create another, new copy of my main form to operate on? And isn't that why I can't see my label text change on my main form that is previously in view?
All of the examples that I have been able to find show using this new key word to be able to access a component on another form. But to my understanding, I'm creating another, new form.
In my program I have WinForm and on this WinForm I have a User Control. On the User Control I have a TreeView.
So what I'm trying to do is passing a number, which is in the TreeNode Text to the WinForm. On the Winform I have a couple of Labels which I want to fill with Informations. To get those informations I have a class with a method which Needs my number from the User Controller. But I can not Access the Labels in the WinForm Method.
Here my code:
User Control
private void TreeView_SelectedNode(object sender, TreeViewEventArgs e) {
CwiaMain frmMain = new CwiaMain(TFS, TfsConnect);
TreeNode tn = _tvWorkItemList.SelectedNode;
if (tn == null) {
