I need help figuring out how to count sentences from a .txt file.
The following guild lines are what is considered to be a sentence:
1. A TERMINATOR followed by two spaces
2. A TERMINATOR followed by one space and end-of-line
3. A TERMINATOR followed by end-of-line
4. A TERMINATOR followed by a double quote and a space
5. A TERMINATOR followed by a double quote and an end-of-line
terminators are '.', '!', '?'
the file i'm reading from is a test file that contains 4 sentences the problem I've found so far is that it's not recognizing '.', '!', '?' and just counting the end of lines and its counting 8 of them. I've spent 4 hours fiddling with the code could anybody give it a look and see what I'm doing wrong?
Body:
C is a general-purpose programming language. It has been closely associ-
ated with the UNIX system where is was developed, since both the system
and most of the programs that run on it are written in C. The language,
however, is not tied to any one operating system or machine; and although
it has been called a "system programming language" because it is useful
for writing compilers and operating systems, it has been used equally well
to write major programs in many different domains.
This file contains 91 words and four sentences!
(First half of code is for counting words, its working)
