A pointer to a bound function may only be used to call the function

Question

I'm working on a homework assignment for my C++ class and have ran across a problem that I cannot figure out what I am doing wrong.

Just to note, the separation of the files is necessary and I realize this would be much easier if I just made a structure AttackStyles inside the main and forgo the additional class file altogether.

The base of my problem is that I cannot seem to be able to loop through an array of classes and pull out base data. Here is the code:

// AttackStyles.h
#ifndef ATTACKSTYLES_H
#define ATTACKSTYLES_H
#include <iostream>
#include <string>
using namespace std;
class AttackStyles
{
private:
    int styleId;
    string styleName;
public:
    // Constructors
    AttackStyles();  // default
    AttackStyles(int, string);
    // Destructor
    ~AttackStyles();
    // Mutators
    void setStyleId(int);
    void setStyleName(string);  
    // Accessors
    int getStyleId();
    string getStyleName();  
    // Functions
};
#endif
/////////////////////////////////////////////////////////
// AttackStyles.cpp
#include <iostream>
#include <string>
#include "AttackStyles.h"
using namespace std;
// Default Constructor
AttackStyles::AttackStyles()    
{}
// Overloaded Constructor
AttackStyles::AttackStyles(int i, string n)
{
    setStyleId(i);
    setStyleName(n);
}
// Destructor
AttackStyles::~AttackStyles()    
{}
// Mutator
void AttackStyles::setStyleId(int i)
{
    styleId = i;
}
void AttackStyles::setStyleName(string n)
{
    styleName = n;
}
// Accessors
int AttackStyles::getStyleId()
{
    return styleId;
}
string AttackStyles::getStyleName()
{
    return styleName;
}
//////////////////////////////////////////////
// main.cpp
#include <cstdlib>
#include <iostream>
#include <string>
#include "attackStyles.h"
using namespace std;
int main()
{
    const int STYLE_COUNT = 3;
    AttackStyles asa[STYLE_COUNT] = {AttackStyles(1, "First"), 
                                     AttackStyles(2, "Second"), 
                                     AttackStyles(3, "Third")};
    // Pointer for the array
    AttackStyles *ptrAsa = asa;
    for (int i = 0; i <= 2; i++)
    {
        cout << "Style Id:\t" << ptrAsa->getStyleId << endl;
        cout << "Style Name:\t" << ptrAsa->getStyleName << endl;
        ptrAsa++;
    }
    system("PAUSE");
    return EXIT_SUCCESS;
}

My question is why do I get the error:

  "a pointer to a bound function may only be used to call the function"

on both ptrAsa->getStyleId and ptrAsa->getStyleName?

I cannot figure out what is wrong with this!

Solution 1

You are missing () around the function calls. It should be ptrAsa->getStyleId().

Solution 2

You are missing parenthesis on both calls, it should be

ptrAsa->getStyleId() 

to call the function.

ptrAsa->getStyleId 

is used to refer to a member value / attribute.

Solution 3

You need to invoke the function, not merely reference it:

    std::cout << "Style Id:\t" << ptrAsa->getStyleId() << "\n";
    std::cout << "Style Name:\t" << ptrAsa->getStyleName() << "\n";

Solution 4

You are Forgot to put () in last in Your Function(ptrAsa->getStyleId ) Calling with arrow operator.
