without using map 1. Write a C++ program to find out the top 10 words in terms of number of appearances in a given file, named “picasso.txt”. The data file is to be downloaded from iLMS system (http://lms.nthu.edu.tw). (Hint: The most efficient way to handle this problem is to build a word dictionary using class map in STL (Standard Template Library) if you know how to do it. On the other hand, without using map, it is still possible to...
