returning an array

[System_Error]

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

The error:

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

The code:

char* possible_array = hist.get_least_obj_occurances();

The error:

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

The 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:

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.

T return_array[same_occur];

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

Thanks. That worked perfectly.
