    <p>The program takes a string using getline, and then passes that string to a function where it stores the string into substrings separated by whitespace. I did that just by reading characters with a loop.</p> <p>However, now I'm trying to pass a second string argument that separates the strings into substrings if the loop encounters characters in the 2nd string argument. This is what I have so far.</p> <pre><code>#include "std_lib_facilities.h" vector&lt;string&gt; split(const string&amp; s, const string&amp; w) // w is second argument { vector&lt;string&gt; words; string altered; for(int i = 0; i &lt; s.length(); ++i) { altered+=s[i]; if(i == (s.length()-1)) words.push_back(altered); else if(s[i] == ' ') { words.push_back(altered); altered = ""; } } return words; } int main() { vector&lt;string&gt; words; cout &lt;&lt; "Enter words.\n"; string word; getline(cin,word); words = split(word, "aeiou"); // this for example would make the letters a, e, i, o, // and u divide the string for(int i = 0; i &lt; words.size(); ++i) cout &lt;&lt; words[i]; cout &lt;&lt; endl; keep_window_open(); } </code></pre> <p>However, obviously I can't do something like</p> <pre><code>if(s[i] == w) </code></pre> <p>because s[i] is a char and w is a string. Do I need to use a stringstream to parse the string instead of the loop I implemented? I actually played around with stringstream, but don't really know how it could help because either way I have to read the characters 1 by 1.</p> <p>P.S. The arguments to split must be passed as strings, and the input form in main() must be a getline.</p>

    1. COIt seems, based on the restrictions on using strings and getline in your P.S., that this might be homework. If it is, please use the "homework" tag on your question.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
