C++ Using STL Multimap

Need help with: I have the code that retrieves the map values and displays to the map, now I need to input the resulting values from the map and transpose them in a multimap and output the letters in the order of its occurrence(amount of times each letter is repeated within the string). (arranged from: least # of times --- to greatest # of times repeated).

Example of what I need:

Enter a text string: fghjkjhjhhjkfgdfghjk The frequency table: [d]->1 [f]->3 [g]->3 [h]->5 [j]->5 [k]->3 The occurance table - a transposed multimap: [1]->d [3]->f [3]->g [3]->k [5]->h [5]->j
