My Pig Latin code doesn't work

Question

I am sure that code run perfectly but when I put it in the playground question doesn't work, even when the answer is the same of the expected.
My code is the following:

#include <iostream>
#include <sstream>

using namespace std;

int main() {
string msg, word;
string wd = "";
getline(cin, msg);
stringstream ss(msg);

while(ss>>word){
int len=word.length();
for(int i=1;i<=len;i++){
wd = wd + word[i];
}
wd = wd + word[0] + "ay";
cout << wd << " ";
wd = "";

}
return 0;
}

Answer 1

Strings are zero-indexed, the character at position word.length() is therefore not a valid character of the string; accessing it is undefined behaviour.
Change the condition of your for loop to

for ( ...; i < len; ... )

in order to fix the problem.

Answer 2

A͢J - S͟o͟l͟o͟H͟e͟l͟p͟e͟r͟ I don't think that is an issue, as all whitespace at the end of the string seems to be ignored anyway. I can print something like " \f \n \r \t \v " at the end and still pass the challenge.

I think that is working fine. He is getting expected result but I think adding extra space in result.

Yes got it. The problem was with index. That should be like:

for (int i = 1; i < len; i++)
