if (s[i] >= 'a' && s[i] <= 'z')
count_small_letters++;
}
int count_words = 0;
bool new_word = true;
for (int i = 0; i < s.length();i++) {
if ((s[i] >= 'a' && s[i] <= 'z') || (s[i] >= 'A' && s[i] <= 'Z')) { // is letter
if (new_word) {
count_words++; & //counting new words
new_word = false; //counting only first letters of the words
}
}
else new_word = true; //symbols between words shows that next letter will begin new word
}
cout<< count_words << " words in sentence." << endl;
cout<< count_small_letters << " small letters in sentence." << endl;
system("pause");
return 0;
