Answer 1

i am using this to take input to create an array of words with whitespaces.but after ending of sentence using Enter, i am not getting any output.

That's because

while (std::cin >> word)
  words.push_back(word);

does not stop when you press Enter

It stops when there is no more data in std::cin. You have to enter EOF to get out of the while loop.

Answer 2

using

getline(cin,word) 

instead of

cin<<word 

will allow you to input words with whitespaces.

Even, vector starts at index 0, hence output

words[0]

instead of

words[1]

will output the entered value. that is the problem.
