Question

Please help in C++

The image contains a C++ program with a commented task at the top, instructing to modify a word counting algorithm to count sentences instead. Specifically, the task highlights the issue of incorrectly identifying ellipses ("...") as multiple sentences. The criteria for a sentence end in this context include a period, exclamation point, or question mark that is followed by two spaces or a newline. The code snippet, `words.cpp`, is as follows: ```cpp #include <iostream> using namespace std; /** * A state filter which counts words that * are separated by non-alphanumeric characters. */ int main() { bool inAWord(false); // haven't read anything yet int words(0); // so we have no words char ch; while (cin.get(ch)) { if (! (isdigit(ch) || isalpha(ch))) // any non-alpha-numeric character { if (inAWord) // transition leaving a word { inAWord = false; words++; } } else { inAWord = true; } } cout << "There were " << words << " words." << endl; } ``` ### Explanation: - **Headers and Libraries**: The program begins by including the iostream header for input/output stream operations. - **Namespace**: The `std` namespace is used, allowing direct access to functions and objects like `cin` and `cout`. - **Comment Block**: A brief description mentions that the program is designed to count words separated by non-alphanumeric characters. - **Main Function**: - **Variables**: - `bool inAWord(false);`: A boolean to track whether the current character reading position is inside a word. - `int words(0);`: A counter for the number of words. - **Input Loop**: A `while` loop reads characters from the input: - **Character Condition**: Checks if a character is non-alphanumeric using `isdigit()` and `isalpha()`. - **Word Transition**: If non-alphanumeric is found while `inAWord` is true, it denotes the end of a word and increments the counter. - **Reset**: Sets `inAWord` to false, indicating the absence in a word context or true if inside a word. - **Output**: Finally prints the count of
