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 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;
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
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?
I have kept dummy as the data to be aligned.I will update hours, minutes, and seconds , but will not use dummy in any case. If I don't initialize 'dummy' does it make any errors ? Do I need to initialize hours, minutes, seconds as well before I use the structure ? If so is there any particular reason ?
I am getting this message from Valgrind, As far as I can see what it points to is initialized. The memory it is referring to is freed in unload and I was not getting this error until after I added the check function. Valgrind was happy. Here is the code and the error message from Valgrind. I am trying to create a spell checker for an assignment for a online class I am taking. I just want to get this table working correctly before I add it to the rest of the program. The code seems to run fine but I have come to see that dos not mean much in C.

I have airport class which should navigate planes, in its list to runways, with method move, theres a method prepare which changes the direction of flight to all planes, always before move is called, move just increments decrement x and y of plane in its list. But after calling two times in row airport->move(), I get screwed and I really dont know wheres the problem. Have I badly initiazed something? Iterator gets invalidated.
Valgrind Stacktrace Conditional jump or move depends on uninitialised value(s) ==26207== at 0x409601: plane::move() (in /home/xnovak11/Downloads/airport/main) ==26207== by 0x401FBD: airport::move() (in /home/xnovak11/Downloads/airport/main) ==26207== by 0x405FE1: io::start(std::istream&, std:stream&, std:stream&) (in /home/xnovak11/Downloads/airport/main)
This is the method where it fails. When I call it once, no problem, after second call I get instead of normal number in cout<<after move<< s1 i get like 8795456 ....
I discovered valgrind and started using it for my c code. But I get following error message at almost every malloc position, :
==19505== 40 errors in context 10 of 12: ==19505== Use of uninitialised value of size 8 ==19505== at 0x10000416E: my_method (main.c:662) ==19505== by 0x10000159E: main (main.c:182) ==19505== Uninitialised value was created by a heap allocation ==19505== at 0x47F1: malloc (vg_replace_malloc.c:302) ==19505== by 0x100001C21: my_method (main.c:333) ==19505== by 0x10000159E: main (main.c:182)
and I really don't understand what it means. I already googled it but I didn't find out what is my mistake.SO here i just put one example:
Code:
int main(int argc, char** argv) {
//i declare my variables at this position Uint *used, *forbidden_jumps, *forbidden_jumpsV, *forbidden_jump;
/*now i want to allocate one of them, this is my line 333 from the error message*/
//a_num is set during the execution of the program, ALLOC(used, Uint, a_num); }

Is there any support page for the output of valgrind? I found it on the homepage.
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;
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.
#include <iostream> #include <vector> using namespace std;
using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace Furniture { class Program { static void Main(string[] args)

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.
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.
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?
when i compile my code i get this error : "error : variable-sized object 'largeArray2' may not be initialized"
Code:
float give_coefficients_routh_table_and_fill_two_first_lines(int denominator_degree) { float largeArray2[20][20] = {0}; int l = 0; int c = 0; int e = denominator_degree ; for ( e = denominator_degree; e>=0; e--)
I am working on a physics engine, following the cyclone physics engine source code but a I am having trouble with an error that is occurring in my overloaded operator== function. It is saying that the information is unaccessible.
Im building a banking system. in my create_account it asks for account address and phone number as well as other questions. When I go to my Show account info (balance inquiry) I notice its not getting the right address as well as phone number. its showing "garbage".

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.
I am modifying a set of static variables inside of the class's member function. The static variables are private. An example of what I'm doing is as below,
utilities.h ----------- class utilities { private: static int num_nodes;
public: void parse_details(char* );
[Code] ....
I get a compilation error in the function void utilities::parse_details(char* filename)
which says: undefined reference to `utilities::num_nodes'
