    copied!<p>I'm sorry if this is a repeat question but I already tried to search for an answer and came up empty handed. So basically I just want to add strings (single words) to the back of a vector and then display the stored strings as a single string. I am quite the rookie.</p> <pre><code>#include &lt;iostream&gt; #include &lt;vector&gt; #include &lt;string&gt; #include &lt;cctype&gt; using namespace std; int main(int a, char* b []) { vector&lt;string&gt; userString; string word; string sentence = ""; for (decltype(userString.size()) i = 0; i &lt;= userString.size() - 1; i++) { cin &gt;&gt; word; userString.push_back(word); sentence += userString[i] + " "; } cout &lt;&lt; sentence; system("PAUSE"); return 0; } </code></pre> <p>Why doesn't this work?</p> <p><strong>EDIT</strong></p> <pre><code>int main(int a, char* b []) { cout &lt;&lt; "Enter a sequence of words. Enter '.' \n"; vector&lt;string&gt; userString; string word; string sentence = ""; / int wordCount = 0; while (getline(cin, word)) { if (word == ".") { break; } userString.push_back(word); } for (decltype(userString.size()) i = 0; i &lt;= userString.size() - 1; i++) { sentence += userString[i] + " "; wordCount += 1; if (wordCount == 8) { sentence = sentence + "\n"; wordCount = 0; } } cout &lt;&lt; sentence &lt;&lt; endl; system("PAUSE"); return 0; } </code></pre> <p>So my new program works. It just puts values at the back of a vector and prints them out 8 words to a line. I know there's easier ways but I'm just learning vectors and I'm going in baby steps. Thanks for the help guys.</p>
