C/C++ :: Uninitialized Local Variable Errors

Sep 7, 2014

I keep getting the "Uninitialized Local Variable" error. But for my code it's says it's the variable 'pay' in my Manager Function. This is the only error that is popping up.

I've tried setting pay to 0 but when I do, I get a bunch of external errors. I've also tried assigning pay to WeeklySalary like this:

double pay = WeeklySalary;

//Calculating pay for a company

#include <iostream>
#include <iomanip>
using namespace std;

//Function prototypes
double managerFunction();
double hourlyWorkerFunction();
double commissionWorkerFunction();

C++ :: Error Stating Variable Is Uninitialized?

Jan 8, 2015

#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.

Visual C++ :: Local Variable Be Passed As Parameter Into A New Thread?

Apr 1, 2013

Can local variable be passed as the parameter for a new created thread procedure? Here is the example code:

Code:
void CDLG::some_function()
{
CString strFileName="abc.doc";
//local variable, can it be valid for being passed into the following new thread???
//Can strFileName still be accessed from within the stack of thread procedure?
::AfxBeginThread(ProcessContentThread,(LPVOID)&strFileName);
}

[Code]...

There is another method using variable on the heap,

Code:

void CDLG::some_function()
{
CString strFileName="abc.doc";
CString* pstrFN=new CString(strFileName);
::AfxBeginThread(ProcessContentThread,(LPVOID)pstrFN);
}

[Code]...

I test these code, both methods work as expected, but I doubt whether the first method is a good way. OR if only the second method is the correct way to pass a parameter to a thread.

C++ :: Compiler Auto Correct Uninitialized Variable?

Jul 13, 2012

I had a flawed function like this:

Code:
fn(){
char c;
if (runFirstTime){
#ifdef VC
c='';
#else
c='/';
#endif
}
... // c is used in the rest of the function to construct some pathnames
}

The problem is that the value of c is not defined the 2nd time the function is called (and subsequently). It somehow worked fine under CygWin compiled with gcc. So I didn't spot the flaw until it ran incorrectly under Windows complied with VC++ 2010. Then I found the error and changed the code to something like

Code:
fn(){
#ifdef VC
const char c='';
#else
const char c='/';
#endif
...
}

So now it works correctly under Windows. Then I re-compiled the new code with gcc and to my surprise gcc produced exactly the same binary! How can this be? Does the gcc compiler see my flaw and fix it for me somehow?

C :: Transform Local Variable Into Global Variable?

Oct 25, 2014

I need to transform a local variable into a global variable so I can use it in one of my functions. I thought about passing the value as a parameter to this function but I can do this since the function is called inside the while loop and this variable counts how many times the while loop does (so the final value is outside the loop). Example to visualize better:

Code:
while(condition) {
function(parameter1, parameter2);
count = count + 1;
}
printf("%d
", count);

So, I need to transform the final value of "count" into a global variable. Can I do this?

Visual C++ :: Error / M4 Failed With Exit Code 255

Dec 8, 2013

Basically, I'm moving a VC project from my Windows 7 build machine to a new build machine that's running Windows 8.1. One of the pre-build steps (for a particular project) runs a script which needs to call the M4 macro processor (which is installed on my C: drive). I've been pretty careful to set everything up the same on both machines (including my PATH) but when I try to build the project on my Windows 8 box, MSVC's IDE shows me this error output when running the script:-

m4 failed with exit code 255

C :: Returning A Pointer To Local Variable

Aug 18, 2014

Should i never return a pointer to a local variable. i have seen the following code in the standard text book.

Code:

struct node *add_to_list(struct node *list, int n)
{
struct node *new_node;
new_node = malloc(sizeof(struct node));
// some code here
return new_node;
}

new_node is a local pointer then why is he returning the new_node? Is it wrong or am i failing to understand something?

C++ :: Temp Or Local Variable Warning

Feb 28, 2014

Here is my overloaded operator :

const double & Waz::operator()(int i,int j) const {
return ((WazImpl const)(*p))(i,j);
}

Where in Waz class I have : WazImpl* p; and in the class WazImpl I have an operator () const

The warning is : Warning C4172 returning address of local variable or temporary

As far as I understand I'm returning a temp variable which is destroyed somewhere else what can I do to fix it?

C++ :: Returning Address Of A Local Variable?

Jul 9, 2014

I know that this code is wrong because it returns the address of local variable which no longer exist after function:

int *f1()
{
int x = 2;
return &x;
}

However, why this one does not show problem and runs fine, here the pointer p is also a local variable:

int *f2()
{
int x = 2;
int *p;
p = &x;
return p;
}

C# :: Unassigned Local Variable In Pay Calculator

Nov 15, 2014

{
//Declare Variables
decimal hrsWrkd, otPay, grossPay, taxRate=0, taxAmount, netPay,basePay, wage;
string maritalStatus;
const decimal WORKWEEK = 40;
const decimal OTRATE = 1.5m;
const double m = 0.15;

[Code] ....

The error message I am getting is Use of unassigned local variable 'otPay' . I see its been declared and been used in the code so the error is confusing, also when i run the program i noticed that it doesn't take out the taxes.

C :: Return Local Variable - Infix To Postfix

Nov 21, 2014

So I have been working my way through this assignment and I'm just stuck now. I cannot get this work properly It just tells me I'm trying to return a local variable when attempting to return postfix in the to_postfix function. It is line 97 that wont compile. Also I cannot change anything in runner.c.

C/C++ :: Local Variable Declaration - While Loop Expression

Feb 3, 2013

I got the following lines of code from a book. The variable char c is being used here to demonstration local variable declaration.

  while(char c = cin.get() != 'q') {
    cout << c << " wasn't it" << endl;
    if(char x = c == 'a' || c == 'b')
      cout << "You typed a or b" << endl;
    else
      cout << "You typed " << x << endl;
  }

It compiles and runs. There are two issues when I try to run it.

1) It seems to loop through two times for every entry. If I insert cin.ignore() just before the closing bracket, it seems to work better.

2) the variable c does not seem to have the character I entered when examined in the if statement.

What is happening with the variable c inside the while loop scope?

Does c actually get initialized?

C/C++ :: Create Local Instances Of A Global Variable?

Oct 4, 2012

is it possible to have a global variable pointing to a different address depending on the thread?

Imagine one would like to use threads with the loop:

for (i=0;i<n;i++){
globalPointerVariable=getAddress(i);
DoThingsUsingThe_globalPointerVariable();
}

C++ :: How To Pass Address Without Creating Local Variable

May 14, 2012

I am doing a piece of gui code on some embedded system.

I'm trying to find a way of eliminating the local variable kEvent:

Code:
EVENT kEvent;
....

Code:
kEvent = EVENT_UPSTREAM;
xStatus = xQueueSendToBack(getEventProcessorQueue(),&kEvent, 0 );
....

I tried this, it doesn't work:

Code:
xStatus = xQueueSendToBack(getEventProcessorQueue(),(EVENT *)EVENT_UPSTREAM, 0 );

Shouldn't this work?

C :: String Declaration As Global / Main Local Variable

Nov 14, 2013

When a declare a string e.g.

Code:
char str[30]; as a global variable, the srting is initialized to NULL.

But if I declare char str1[30] INSIDE main(), then the string has garbage inside.... Why this happens??

E.g. the following code snippet...

Code:
#include <stdio.h>
char str[50];
int main(){
char str1[50];

Visual C++ :: Static Variables Local Or Global?

Mar 10, 2014

I came across the following code today and I was a bit surprised that it worked:-

Code:
std::string func_A () {
static std::string x;
if (!x.empty())
return x;

[Code] ....

I've simplified things slightly - but the basic point is that both functions are in the same source file and they both have a static std::string called 'x'. Being static, I guess they aren't (strictly) local variables. So how does the compiler know that they're different entities? Does it encode their signatures using the function name or something like that? If I call each function separately I do seem to get the correct string...
