I made this pig latin translator in c++ and I was wondering what I could improve and what is good about it. I used the stringstream class to get the individual words and I was also wondering how that works because I know what it does but I don’t know how it works. Thanks in advance.

#include <iostream> #include <vector> #include <sstream> std::string translate(std::string word){    if(word.length() > 1){        word += word[0];        word[0] -= word[0];        word += "ay";    }    return word; } int main(){     std::vector<std::string> v;     std::string str = "Hello the world has ended";     std::stringstream stringStream(str);     for(int i = 0; i < str.length(); i++){         std::string currentWord;         stringStream >> currentWord;         v.push_back(currentWord);     }  for(int i = 0; i < v.size(); i++){     std::cout << translate(v[i]) + " "; }  std::cout << std::endl;  }
