    <p>As a beginner I am trying to input one digit numbers in word form, but sort and display them as numbers. </p> <p>On inputting :</p> <p>seven three five one nil</p> <p>the output is</p> <p>0 1 3 5 7 How can i stop 0 from displaying and from being populated in num array in first place?</p> <pre><code>#include &lt;iostream&gt; #include &lt;algorithm&gt; #include &lt;string&gt; #define n 5 using namespace std; string words[n]; int nums[n],size; void input(){ cout&lt;&lt;"Enter in word form, the numbers to be sorted\n"; for( int i = 0; ; i++){ cin &gt;&gt; words[i]; if( words[i] == "nil" ) break; } size = sizeof words/sizeof(string); } void convert(){ for( int i = 0; words[i]!= "nil" ; i++ ){ if ( words[i] == "one" ) nums[i] = 1; // else cout&lt;&lt;"Wrong input\n"; } } void sort(){ sort(nums, nums + size); for ( int i = 0; i &lt; size; i++ ) cout&lt;&lt; nums[i]&lt;&lt;endl; } int main(){ input(); convert(); sort(); system("pause"); return 0; } </code></pre> <p>This works fine, I erred at length of words..to remove element nil (used as sentinel) from consideration of sort i had to reduce size by 1 . This code works just fine and the way it is intended to.</p> <pre><code> //headers and std string words[n]; int nums[n],size; void input(){ cout&lt;&lt;"Enter in word form, the numbers to be sorted\n"; for( int i = 0; ; i++){ cin &gt;&gt; words[i]; if ( words[i] == "nil" ) break; } size = sizeof words/sizeof(string) - 1;//one for nil } void convert(){ for( int i = 0; words[i]!= "nil" ; i++ ){ if ( words[i] == "one" ) nums[i] = 1; else if ( words[i] == "two") // } } void sort(){ sort(nums, nums + size); for ( int i = 0; i &lt; size; i++ ) cout&lt;&lt; nums[i]&lt;&lt;endl; } int main(){ // } </code></pre>

    1. COMost likely, you are overwritting the bounds of allocated array. Also, why do you fill the array from `1` index and not `0`? In C and C++ `0` is the first index. The valid index range is `0` to `N-1`.

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.
