C++ :: Quantlib / Error C2064 - Term Does Not Evaluate To A Function Taking 1 Arguments

Dec 8, 2014

The first call of my function works with empty vectors but fails when dimensions are introduced to the vectors.

When "uncommented, the commented out function call fails with the error above.

C/C++ :: Error C2064 / Term Does Not Evaluate To A Function Taking 1 Arguments

Aug 7, 2014

i'm implementing a templated function callback.

I get this error:

"error C2064: term does not evaluate to a function taking 1 arguments"

I'm not sure why.

Here's the code for the template function in the timer class header:

template<class T>
void TimerEvent(DateAndTime DateTime, std::function<void(T)> Callback);

Now the class body:

template<class T>
void GameTimer::TimerEvent(DateAndTime DateTime, std::function<void(T)> Callback)
{
DateAndTime time;
time.Now(false);
if (time.Compare(DateTime) == 1)
Callback(T);
}

and calling the class in the Engine:

int test1(int a)
{
}
void Main()
{
gameTime.TimerEvent<int>(gh, test1(1));
}

C++ :: Calling Function Address - Too Many Arguments For Call Error

Nov 25, 2014

In C you can just load and call the address of a function without defining its arguments like this:

Code: int (__stdcall *pMessageBox)();
int main() {
HMODULE h=0;
h = LoadLibrary("user32.dll");
pMessageBox = GetProcAddress(h, "MessageBoxA");
// MessageBoxA
pMessageBox(0, "MessageBoxA has been called!", "MessageBox Example", MB_OK);
return 0;
}

In C++ the same code gives "too many arguments for call" error unless you define the function first with its parameters.

Is there a way to do it the same way in C++?

C++ :: Debug Error When Taking A String And Casting It To Float With File Stream

May 9, 2014

Debug Error

ProjectsFinal ProjectGrItemDebugGrItem.exe

R6010 - abort() has been called

I was going over this with a friend and it seems as though getline() is not reading anything in and thus throwing the abort error. I'm not sure why this is because I've included the textfile, with the correct name of course, in both the regular file location and the debug folder. I ask for user input and the user then inputs the name of the file they want, I do some required things behind the scenes and display the results for them in a cmd window. I've included pastebin files for both my header and cpp files because it is far to large for one post I shall, however, post the full code in the comments.

Quick Code

The problem occurs on line 159. I'm assuming once this line is fixed, line 163 will have the same problem.

// Read regular price
getline(nameFile, input, '$');
vectorList[count].regPrice = stof(input.c_str());// Casts string to a float
// Read sale price
getline(nameFile, input, '#');
vectorList[count].salePrice = stof(input.c_str());

C/C++ :: Template Class Function Taking A Derived And Generic Object

Feb 23, 2014

I'm trying to write a function for receiving messages, so my classes can communicate with each other. The only issue I get is a compile error asking me to define the base parameter as one of the derived instances. I tried using a void* to fill the need, but then I lose the initial type, which I need to check for. How might I go about writing a generic object for this?

Here's my code:

template<class Object>
class State
{
public:

[Code].....

Should I just have all of the objects inherit in the order of Object >> GenericObject >> DerivedObject?

C :: Algorithm To Find Kth Term Of A Series

Dec 8, 2014

I want to write an algorithm to find the kth term of a series given by the following recursive formula:

a_0=1 and a_(k+1)=a_k+1/k!

My code (part of it responsible for calculating the value of a series) does not want to compile:

Code:

float series(int n)
{
float F0 = 1;
float F;
unsigned int i;
if (n == 0)
return(1);

[Code]...

thus my question is why it does not want to work properly and what should i change (for certain factorial function is OK)?

C++ :: Define A New Member Method Which Calculates Value Of Term And Display It

Jul 30, 2012

A class called 'sample' with the data a, b and c and two methods as defined below. Define a new member method 'term()' which calculates the value of the term (2b - 4ac) and displays it.

Define the method outside of the class definition. Write the main method to create an array of 2 objects called D of class 'sample' and display the values and find the solution to the term (2b - 4ac)

My code so far:

#include <iostream>
using namespace std;
int term(int a, int b, int c) {
int result;
result = (2*b - 4*a*c);

[Code] ....

Problem: I keep getting error messages, here is a look at the ones i'm getting.

error: ISO C++ forbids declaration of 'cout' with no type.
error: expected ';' before '<<' token.
error: new types may not be defined in a return type
error: expected unqualified-id before '{' token.

C :: Arguments When Declaring A Function?

Jun 5, 2013

I am a bit confused about how specific one must be with arguments when declaring a function. I'll show you two functions from the book I'm using to learn C to show you what I mean.

Example 1 (greatest common denominator function):

Code:
void gcd (int u, int v) {
int temp;
printf ( "

[Code] ....

So in that function, there are exactly two arguments, because that's how many arguments the algorithm to find the gcd takes. No problem there, makes sense to me. Then further in the chapter on functions I run into this,

Example 2 (square root function):

Code:
float absoluteValue (float x) {
if ( x < 0 )
x = -x;
return x;

[Code] ....

In this second example, we have a square root function that is preceded by an absolute value function. The absolute value function has the one argument, "float x", however when this function is called within the square root function, the arguments "guess * guess * -x" are passed to it. I'm confused how this absolute value function is working with all of that inside it, when it was originally declared with just "x." The only possibility I can think of is that this expression is treated as a single unit, but I'm not sure.

C :: Function With Multiple Arguments

Jan 15, 2015

I am actually developing an nginx module in C.I am not to bad in C, but i got a big problem to pass argument to a vadiadic function.This function look like the well good old printf, but you put a buffer as first argument, the last address to stop to put data as second argument (in my case it is the last adress of disponible memory), a string that look like one in printf, an the other argument after.Here is the problem, the 4th last argument does not have the good value. In fact, It seem to be random value from memory. I Use gcc (Debian 4.9.1-19) 4.9.1.

Code:

/* ngx_html_log.h */
#ifndef NGX_HTML_LOG_H
#define NGX_HTML_LOG_H
#include <ngx_vasm.h>

C++ :: Function With Template Arguments

May 26, 2013

I'm trying to create a callback wrapper for pointers to member functions of any class by using templates, std::function and std::bind. This will be used to send incoming sf::Event's to classes who register callbacks with an event manager. I based my code off of the example on this page: URL.....Here's what I have:

class EventCallback
{
std::function<bool(const sf::Event&)> func;

public:
template<typename T>
EventCallback(T* object, bool(T::*func)(const sf::Event&)) { func = std::bind(func, object, std::placeholders::_1); }
bool run(const sf::Event& evt) { return func(evt); }
};

C :: Function Fails On Even Number Of Arguments

Nov 3, 2013

What I have is a main function that takes input characters from the command prompt during the main function call, and coverts it to an integer array a using atoi. (starting at the 2nd character - the 1st is reserved for another call that I plan to reference later, and the 0th is obviously the ./function). A function is then called to find the mode of an array (the range of values in the array is 1-30). Now, when I run the whole thing, I get a segmentation fault (core dumped) for even number of arguments. It's late and I've been staring at it for too long...

Code:
#include <stdio.h>
#include <stdlib.h>
int get_mode(int a[], int count);

C :: How To Call Function With Correct Arguments

Sep 13, 2013

I'm not a programmer, at least, not a good one. I'm a researcher and I need to implement this function and test it and use it for my research. I tested some clustering methods in JAVA and Matlab and also I want to test it on C. I don't know too much about programming, especially about C, I know nothing. I tried to implement some basic methods but I failed.

It's all about K-Means Algorithm. I'm working on a disease and I'm trying to find ways to early diagnosis. Anyway, these are details. The thing is, I found a 'free to use' function but I don't know how can I use it. I tried to learn something from Net, I downloaded a compiler, I paste the code and I get many errors... And I heard that I have to do some "calling function" stuff but I don't know how to..

The code is in the link below: URL....It's not imperative that using this function, it can be another one but it had to written in C.

C++ :: Call Function With Arguments From Java

Sep 19, 2013

I am working on a project in a group at a university. We are creating a GUI in Java where the user can enter parameters. Then we want to be able to pass these parameters to a function inside our C/C++ program, that does the rest. How do I do this? So far I have managed to call a simple helloworld-function by using JNI, dll and a javah tool that create a header file from a java file. I define the helloworld-function in C and call it from Java.

Java file:

package helloworld;
public class HelloWorld {
private native void print();
public static void main(String[] args) {

[Code] ....

My problem is that I do not know how to call the helloworld-function with parameters. I guess that this is a special case when using JNI and a . dll. How do I pass simple char- and int-arguments from the Java class to the helloworld-C-function?
