    copied!<p>So, I have a project that must add, delete, and print the contents of a vector... the problem is that, when run the program exits before I can type in the string to add to the vector. I commented the function that that portion is in.</p> <p>Thanks!</p> <pre><code>#include &lt;iostream&gt; #include &lt;cstdlib&gt; #include &lt;vector&gt; #include &lt;string&gt; using namespace std; void menu(); void addvector(vector&lt;string&gt;&amp; vec); void subvector(vector&lt;string&gt;&amp; vec); void vectorsize(const vector&lt;string&gt;&amp; vec); void printvec(const vector&lt;string&gt;&amp; vec); void printvec_bw(const vector&lt;string&gt;&amp; vec); int main() { vector&lt;string&gt; svector; menu(); return 0; } //functions definitions void menu() { vector&lt;string&gt; svector; int choice = 0; cout &lt;&lt; "Thanks for using this program! \n" &lt;&lt; "Enter 1 to add a string to the vector \n" &lt;&lt; "Enter 2 to remove the last string from the vector \n" &lt;&lt; "Enter 3 to print the vector size \n" &lt;&lt; "Enter 4 to print the contents of the vector \n" &lt;&lt; "Enter 5 ----------------------------------- backwards \n" &lt;&lt; "Enter 6 to end the program \n"; cin &gt;&gt; choice; switch(choice) { case 1: addvector(svector); break; case 2: subvector(svector); break; case 3: vectorsize(svector); break; case 4: printvec(svector); break; case 5: printvec_bw(svector); break; case 6: exit(1); default: cout &lt;&lt; "not a valid choice \n"; // menu is structured so that all other functions are called from it. } } void addvector(vector&lt;string&gt;&amp; vec) { string line; int i = 0; cout &lt;&lt; "Enter the string please \n"; getline(cin, line); // doesn't prompt for input! vec.push_back(line); } void subvector(vector&lt;string&gt;&amp; vec) { vec.pop_back(); return; } void vectorsize(const vector&lt;string&gt;&amp; vec) { if (vec.empty()) { cout &lt;&lt; "vector is empty"; } else { cout &lt;&lt; vec.size() &lt;&lt; endl; } return; } void printvec(const vector&lt;string&gt;&amp; vec) { for(int i = 0; i &lt; vec.size(); i++) { cout &lt;&lt; vec[i] &lt;&lt; endl; } return; } void printvec_bw(const vector&lt;string&gt;&amp; vec) { for(int i = vec.size(); i &gt; 0; i--) { cout &lt;&lt; vec[i] &lt;&lt; endl; } return; } </code></pre>
