    <p>How do I make a binary search replace an element of an array of strings with another element of an array of strings? This is the final part of my program and I don't get it...I know with char's you use strcpy, or .replace, etc. </p> <p>I have a struct that has an "orginalWord" and a "replacementWord", then a string array of "inputword"'s, it takes the inputword, finds it within the struct array (comparing to the orginalWord), and once found (Which it does find it...that part works, it finds the correct element number, so I know the searching is correct) replaces the "inputword" with the "replacementword". I just can't make it replace the element within the "inputword" with the "reaplcementWord" it finds. Help please!! I'll post the Binarysearch function seperate from the rest of my code for easy of reading. I know this should be simple, but I can't remember for the life of me.</p> <p>Example: So...searchitem is inputword[20] = "Like". Sruct Array... encryption[50].OrginalWord = "Like". Match found...encryption[50].ReplacementWord = "Ducks". I would like to put "Ducks" into inputword[20]. How would I do this using the BinarySearch?</p> <pre><code>//Function call within main: for(number=0; number &lt; plaincount; number++) { BinarySearch(encryption, count, inputword[number]); } int BinarySearch (StringPair correctword[], int size, string searchitem) { int middle =0, start = 0, last = size-1; bool found = false; int position = -1; while (!found &amp;&amp; start &lt;= last) { middle = (start + last)/2; // Midpoint // Was a breakpoint here, why? if(correctword[middle].orginalWord == searchitem) { position = middle; cout &lt;&lt; "Replacing word: " &lt;&lt; searchitem &lt;&lt; " With: " &lt;&lt; position &lt;&lt; endl; searchitem.swap(correctword[position].replacementWord); found = true; return position; // Return new value for inputword array? } else if (correctword[middle].orginalWord &lt; searchitem) { start = middle+1; } else last = middle-1; } cout &lt;&lt; "Misspelled word found: " &lt;&lt; searchitem &lt;&lt; endl; return false; } </code></pre>

    1. COAre you trying to make it so that searchitem is modified in the caller?

    2. CO@VaughnCato Yes? Once it finds a match for the words, I want it to replace the element in the string array, that was used as the searchitem. With the string where it found the match at. Hope that makes sense.

    3. COI have a struct array of 2 strings, "OriginalWord" and "ReplacementWord". There's 86 of them. I then have a string array "inputword" of about 200. I use the "inputword" as the searchitem, searching within the struct array comparing to "OriginalWord", which it does find. But once it find it, I want it to take that element number in that array, and use "ReplacementWord" and put that new string, where the element within the string array for "intputword" is that was used as the search item.

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.
