Question

C++

4. Write a loop that reads in a collection of words and builds a sentence out of all the words by appending each new word to the string being formed. For example, if the three words This, is, one are entered, your sentence would be This", then This is", and finally This is one". Exit your loop when a sentinel word is entered.

#include<string>

#include<algorithm>

#include<iostream>

using namespace std;

int main(){

vector<string> words;

cout<<"Please enter quit to stop"<<endl;

string temp;

while(cin>>temp){ //input word

transform(temp.begin(), temp.end(), temp.begin(), ::tolower); //convert word to lower case

if(temp == "quit"){

break;

}

words.push_back(temp); //insert word in the vector

}

for (int i=0; i < words.size(); i++) { //display word in sentences

for (int j=0; j<=i; j++) {

cout <<words[j]<<" ";

}

cout<<endl;

}

}
