returning an array

I'm trying to return an array, but I'm getting errors when I actually try to use the method.

The error:

Quote:

---

318 C:\Dev-Cpp\Projects\Histography\main.cpp instantiated from here

---

The code:

Code:

---

char* possible_array = hist.get_least_obj_occurances();

---

The error:

Quote:

---

151 C:\Dev-Cpp\Projects\Histography\main.cpp invalid conversion from `const char' to `char*'

---

The code:

Code:

---

template <typename T> T* Histogram<T>::get_least_obj_occurances()
{
        typename map<T,int>::iterator ci;
       
        int same_occur = get_same_occurances(0);
        int low = get_least_num_occurances();
       
        T return_array[same_occur];
       
        if (same_occur = 1)
        {
            for (ci=frequency.begin(); ci != frequency.end(); ++ci)
            {
              if (ci->second == low)
              {
                return ci->first;
              }
            }
        }
        else
        {
            int index = 0;
            for (ci=frequency.begin(); ci != frequency.end(); ++ci)
            {
              if (ci->second == low)
              {
                  return_array[index] = ci->first;
                  ++index;
              }
            }
        }
       
        return return_array;
}

It specifically catches on that one bold line.




I'm creating the array with the following line:

Code:

---

char* possible_array = hist.get_least_obj_occurances();

---

Where hist is a histogram object of type char.



If someone can help me with this it would be much appreciated.

Stack frame array requires constant size. use T * return_array = new T[same_occur];

Thanks. That worked perfectly.
