Although the associative array is not a primitive data type, it is one of the most widely used data types due to its versatility and fast performance. In this project, you are to implement'word count' in C++ using an associative array Count the number of unique words in a sentence -Assume that only lower case letters are used, there's only one white space between words in the input sentence, and punctuation mark is separated from a word. -meaning all data preprocessing is done) You can implement your own associative array type, but STL map class performs very well. You can find examples in the CS455/456 textbook or by a google search (e.g https://www.cprogramming.com/tutorial/stl/stlmap.html) Submission hardcopy: attach your source code to this cover sheet softcopy: upload hw5.cpp to CourseWeb (DO NOT submit a zip file) 'll compile your code using g++ hw5.cpp -o hw5 on ACM.
