Why this code doesnt work: error

Question

this code is supposed to take a sentence, then swap first and last letters of each word and add "ay'' at the end of each word

#include <iostream>
#include <string>
#include <vector>
#include <sstream>

int main()
{
std::string input;
int last, first = 0;
char r;

std::cin >> input;

std::istringstream iss{input};
std::vector <std::string> words;
std::string word;
while (iss >> word)
words.push_back(std::move(word));

std::string aword, result;
for (int i = 0; i < words.size(); i++)
{
aword = words[i];

last = aword.front();
first = aword.back();

r = aword[last];
aword[last] = aword[first]; //swap
aword[first] = r;

aword = aword + "ay";
if (i == 0)
result = aword + " ";
if (i == words.size() - 1)
result = result + aword;
else
result = result + aword + " ";
}
std::cout << result;
}

Answer 1

Not gone through entire code... A quick check on cin >> input....

Try to print value of input immediately after taking input post cin.... You will observe that it's not entire string stored in variable...

For input string having space in between , plz use getline(cin,input)

Answer 2

thanks for telling me about getline. i figured out the rest of the code, heres the result
#include <iostream>
#include <string>
#include <vector>
#include <sstream>

int main()
{
std::string input;
int last, first = 0;
char r;

std::getline(std::cin, input);

std::istringstream iss{input};
std::vector <std::string> words;
std::string word;
while (iss >> word)
words.push_back(word);

std::string aword, result;
for (int i = 0; i < words.size(); i++)
{
aword = words[i];

last = aword.length() - 1;
first = 0;

r = aword[last];
aword[last] = aword[first]; //swap
aword[first] = r;

aword = aword + "ay";
if (i == 0)
result = aword + " ";
else if (i == words.size() - 1)
result = result + aword;
else
result = result + aword + " ";
}
std::cout << result;
}
