C++

Write a program that finds rhyming words in a poem. Specifically, the program reads an input file, line by line, and extracts the last word in each line. It then compares this last word with the last word from the line after it. If it finds that the 2 words rhyme (which is simply defined as the 2 words that are being compared share the same 2 last letters), then it prints out these two words to standard output (i.e. the display). But FIRST, the words must be cleaned up of any non-alphabetical characters (usually this means puncuation, since many poems have their last lines often end with a comma, a semicolon, a question-mark, etc) So if the last word on a line has punctuation marks on it, e.g. hello?!, it becomes hello. Or if the last word is dont, it becomes dont.

Finally, the program has to state how many rhyming pairs it found, or if it did not find any at all.

The program has to ask the user for the file name and has to check to see if the file exists (use the string Enter file name: for the question). If it does not exist, the program must output (via cerr) an error message: Input file opening failed. and then exit with code 1.

Your program should define at least one function. If your program does NOT have at least one function, you will not get credit for this part of the assignment, even if your program passes submit.cs grading.

As an example, assume there is a text file called MyPoem.txt, which contains this:

"I cannot go to school today," Said little Peggy Ann McKay. "I cannot go to school and play! I have the measles and the mumps, A gash, a rash and purple bumps. My mouth is wet, my throat is dry, Im going blind in my right eye. My tonsils are as big as rocks, Ive counted sixteen chicken pox" 

The program would run as follows:

Enter file name: MyPoem.txt today and McKay McKay and play mumps and bumps There are 3 pairs of rhyming words.
