IN C++

The filter words counts the number of words in input as long as each word is separated from the next by one or more spaces. Modify the program so that it makes explicit tests for the space, tab and newline characters. Make sure it also counts the last word in a line which doesn't end in a newline. Complete the following file: words.cpp 1 2 #include using namespace std; /** 3 4 5 6 7 8 9 10 11 12 13 14 15 16 A state filter which counts words that are separated by spaces. */ int main() { bool in AWord{false}; // haven't read anything yet int words{0}; // so we have no words char ch; while (cin.get(ch)) { if (ch '') // any whitespace character 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 if (ch == ') // any whitespace character { if (inAWord) // transition leaving a word { inAword = false; words++; } } else { inAword = true; } } cout
