C/C++ :: Initialization Of Fin Is Skipped By Case Label
Jan 28, 2015
This program was running at first but when I started to change the couts and cins to fouts and fins (in order for them to be save in a file directory), it shows a lot of errors such as:
initialization of 'fin' is skipped by 'case' label
'std::ifstream fin': redefinition
Here is the code of the program:
#include <iostream>
#include <iomanip>
#include <fstream>
using namespace std;
struct file{
int fnum;
char fname[50], lname[50];

In this simple end-of-chapter problem, the ages of two people are to be compared and determine who's older. The problem I'm experiencing is that the second user name input is being skipped and going straight to the second users age.
So while running the program it looks something like:
What is user ones name?
<input name>
How old are they?
<input age>
What is user twos name?
How old are they?
<input age>
<if statement result>
Here's my code:
Code: #include <iostream>
#include <string>
using namespace std;
int user_one_age;
int user_two_age;
string user_one_name;
string user_two_name;
[code].....

when i run it , it skips scanf and not allowing user to enter input.tried adding getchar(), fflush but nothing worked for me.
//file name : sort_array_of_structure.c
Code:
/*Write a program to accept records of the different states using array of structures. The structure should contain char state, population, literacy rate, and income. Display the state whose literacy rate is highest and whose income is highest.*/
#include <stdio.h>
#define M 50
struct state
{
char name[50];
long int population;
float literacyRate;
float income;
}

I have something like this
string rid = row.Cells[0].Value.ToString();
string identification = row.Cells[9].Value.ToString();
IDLabel.Text = "ID: " + rid + " <Identification: " + identification + ">";
I checked that while identification has a value, the IDLabel.Text was run just fine, but if identification has null value, IDLabel.Text was skipped totally...

I just dont know how to get my upper case and lower case equal...heres the program: Write a program to calculate utility cost for ACME UTILITY COMPANY. The company has 3 types of customers (R) residential, (C) Commercial and (G) government. Customers are billed based on the number of kilowatts used and they type of customer they are (R,C,or G).
Residential cusstomers are charged 0.25 cents per kilowatt hour for the first 500kw used, and 0.35 cent per kwh for all kw used over 500.Commercial customers are charged 0.22 cents per kilowatt hour for the first 999kw used, 0.29 cents per kwh for all kw used over 999 kw up to 1999 and 0.45 cents per kwh for all kilowatts used greater than 1999. Commercial customers that use over 2000 kw are charged a special surcharge of 100.0 in addition to the regular charges.
Government customers are charged 0.34 cents for the first 1500 kwh used(<=1500). 0.30 cent for the next 1000 kwh(1501-2500) and 0.25 cents for all kwh used over (>=2501)
in addition residential customer are charged .5% tax on the cost utilities while Commercial customers are 5% tax on the cost of utilities not including the special surcharge Government customers are not charged a tax
Code:
#include <stdio.h>
#include <math.h>
int main(void)
{
int R;
int ct;
int kwh;
int taxes;
int surcharge;
int charge
}
[code].....
the program should quit with Q and calculate the amount owed, utility charge, and surcharge

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) {
MessageBox.Show("Error");

With the LoadLibrary function (followed by GetProcAddress) you can get a function or any other thing that is on DLL export. AFAIK, when you assemble one program, it loses all user-reading data (names in general). How do the OS's get them?

System.Drawing.FontStyle newFontStyle;
newFontStyle = FontStyle.Regular;
expanderLabel.SelectionFont = new Font(
currentFont.FontFamily,

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 have a question, is it possible to Concatenate a variable to a label?
For example, i'm doing:
Random Rnd = new Random();
int num1 = Rnd.Next(1, 11);
And now i want to concatenate the random number to give test me if the label of that number has a char inside.
if ( lbl_s_num1.Text != "X")

Here is a function,which deletes the spaces of a string...
char *removespaces(char *s1) {
Code: char *s2=s1;
int i,j=0;
for (i = 0; i<strlen(s1); i++){
if (s1[i]!=' ') {
s2[j]=s1[i];
[Code] .....
why I have to initialize the pointer *s2 with the first element of the array s1...???If I don't initialize the pointer,or initialize it with something else,I get a segmentation fault...

I would like to initialize an arry containing function pointers with adresses of functions that have a variable number of arguments.
Below the code that works in principle. I would however get rid of the warning message during compilation pointing to the initialzation of the funtion pointers in the array. How do I need to cast the pointers to the functions ?
Code:
gcc func_ptr_init.c
func_ptr_init.c:28: warning: initialization from incompatible pointer type
func_ptr_init.c:32: warning: initialization from incompatible pointer type
Code:
#include<stdio.h>
unsigned char func1_ptr(unsigned int* if_desc, int* result_code) {
*if_desc = 1;
*result_code = 1;
return(0);

In a book I'm reading, the author has the following struct:
struct VertexPos {
XMFLOAT3 pos;
};
Where XMFLOAT3 is a structure with x,y,z floating point values within. He declares and initializes an array as the following.
VertexPos vertices[] =
{
XMFLOAT3(0.5f, 0.5f, 0.5f),
XMFLOAT3(3.3f, 5.6f, 3.6f),
XMFLOAT3(-4.5f, 2.2f, 6.4f)
};
It doesn't make sense to me why this is working. The way my mind is thinking about this is that vertices is an array of type VertexPos, so then why can it be initialized with objects of type XMFLOAT3?

I have a class containing a map member that I want to initialize at declaration time. I know I can do it in the cpp file but I'm having a problem with the order of initialization (static initialization order fiasco).
My questions are:
Is it possible that the scenario in which, the Test's constructor's implementation and the map initialization instruction are in the same cpp file and constructor is called when the map is not initialized yet, could happen?
Is it possible to initialize the map in class like I did? I get these errors:
in-class initialization of static data member 'std::map<std::basic_string<char>, Test*> Test::a' of incomplete type
temporary of non-literal type 'std::map<std::basic_string<char>, Test*>' in a constant expression
If yes, does this initialization resolve the static initialization order fiasco?
class Test {
public:
static std::map<std::string, Test*> a = {};//this is an error
Test(std::string ID) {
