C/C++ :: Variable Not Declared In Scope Error?
Jan 27, 2014I'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.

C++ :: Virtual Can Only Exist In Non-static Member Function - Field Has Incomplete Type Void
Dec 5, 2014I'm writing a class "Property" for a program that manages different types of properties. This is my .h for y base class. I was trying to write a virtual void function to convert different children classes to strings that can be displayed, but Xcode is freaking out.
I had it as:
virtual void toString()= 0;
and it gave me an error message: "Virtual can only exist in non-static member functions" and "field has incomplete type 'void'"
I changed it to:
virtual string toString() = 0;
and the error message didn't change.
Is this an issue with Xcode or did I do something wrong? Even after changing it to string it told me that it "has incomplete type 'void'"....
C++ :: Variable Not Being Declared Before Initializing - But It Is?
Mar 31, 2014I'm working on this program, and when i run it for 'p', 'P', or for a incorrect service code a error message pops up saying that "totalCost is being used without being initialized". I don't want to change it to switches, case, and breaks now because I've come too far to change it all. I have that variable right here just below.
#include <iomanip>
#include <iostream>
using namespace std;
int main() {

Error reads: 'x' was not declared in this scope.
How do I fix this?
P.S The sushi class does not matter, that is all perfect. Also, the dots are to represent my tabbing to make it easier to understand.
C/C++ :: Error - Grid Was Not Declared In Scope
Jan 28, 2014I'm trying to make a dynamic 2d array of a Tile Object I created, the Dynamic 2d array was working when I tested it as an int array but not that I gave it a type of Tile it is giving me the above error. I'm reading values from a .txt .

C# :: Field Initializer Cannot Reference The Non-static Field / Public Var
Apr 12, 2015So I have this class
class DataBase
{
// Change the connection path here to your own version of the database
public SqlConnection con = new SqlConnection(@"Data Source=(LocalDB)v11.0;AttachDbFilename=|DataDirectory|UberDatabase.mdf;Integrated Security=True;");
public DataBase()

}
}
And in the same namespace as this class I have a form that calls it like so:
DataBase dBase = new DataBase();
SqlCommand trythis = new SqlCommand("Register", dBase.con);
However, I'm getting the field initializer error on dBase.con. I'm not sure why, but when I call the database from another file (program.cs) it works fine this way.

if possible i want avoid the '&' when i assign the variable address.(variant2 f=varname;//like you see i don't use the '&')
for the moment i just need put the address to Variant pointer. but i receive several errors .

C++ :: Logical Error - Change Value Inside Void Statement
Jul 16, 2013I've encountered a slight logical error in my code

Look at case 2, which the user supposed to key in a new input, the problem is the value will never got into main function, I don't know what should I modify with the function.
Figured out I need to change the
void changeData(int startingAge, int numOfYears,
double lumpSumAmount, double yearlyAmount, double interestRate )
into
void changeData(int &startingAge, int &numOfYears,
double &lumpSumAmount, double &yearlyAmount, double &interestRate )
C++ :: Cannot Cast From Void Pointer - Returns Always Error C2440
Apr 25, 2013I having a problem which I'm not able to resovle. I try to dereference a void pointer but I always get a C2440 error. It says: 'static_cast':void* cannot be converted in wqueue<T>. I tried different cast ways but I always get the same error. As far as I found out I should get the error if I try to dereference without cast but in my case I cast before and still get that error.
void *srumbler (void *arg) {
wqueue<workclas*> m_queue= static_cast<wqueue<workclass*>>(arg);
return NULL;

The according type wqueue in the header file:

C++ :: Why Every First Function Of Each File Get Error - Multiple Definition Of Void Pointer
May 6, 2014I declared all functions in header file, such as:
bool readCase();
bool meshing();
bool readMesh();
bool calculateFlowfield();
bool readFlowfield();
bool calculateEvaporation();
And then I define them in separated .cpp files, each .cpp file include the header, but I got multiple definition error, why?
Even the int main() function, which only decalred and defined once got this error, why?
C++ :: Why Does GetY Have To Be Declared After Struct Y Is Declared
Jan 30, 2013struct x
{
y *GetY(); //error: what is "y"?
struct y
{
};
};
Why does GetY have to be declared after struct y is declared? I thought order of class members in C++ did not matter? Does it have to do with the way parsing is done?
EDIT: It also doesn't work if I typename x::y *GetY();, which makes even less sense to me.
EDIT: It works if I forward declare, but this goes against everything I know about C++ classes...

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.
