Answer 1

#include <iostream>
#include <string>
#include <sstream>
using namespace std;

class StringProcessing{
static const int nMax = 100;
public:
void wordSizeOccurrence(void){
stringstream _s; //stream class to operate on strings (use a string buffer)
string _word, _str;
int wordSize[nMax] = {}; //array filled with 0
getline(std::cin, _str); //extracts characters from std::cin and stores them into _str
_s<<_str; //overwrites the contents _str in _s
while(_s>>_word)
wordSize[_word.length()]++; //increments the array element that meets a given length of words
for(int i = 0; i<nMax; i++) //if there are words with length from 1 to 100 characters, print the number of theirs
if(wordSize[i]!=0) cout<<i<<"-letter words: "<<wordSize[i]<<endl;
}
};

int main(){
StringProcessing ob;
ob.wordSizeOccurrence();
return 0;
