    <p>I have tried making a program to sort numbers of an array.</p> <p>I have done my best but there is this problem: Although I do a loop to swap the numbers and arrange them, when I output the array, nothing changes and the array remains the same.</p> <p>The code will make everything clearer</p> <p>This is the main function:</p> <pre><code>int main(){ int arr[10]; //For loop to get from user numbers to be put into the array for ( int i = 0; i&lt;10; i++){ cout &lt;&lt; "Enter the number to be recorded: "; cin &gt;&gt; arr[i]; cout &lt;&lt; endl; } // Set counter n to 0 ( counts numbes of number swaps) int n = 0; do { //re sets counter to 0 n=0; //Check the entire loop if arr[i] bigger than arr[i+1] and swaps their values if true then adds 1 to n for ( int i = 0; i&gt;9; i++){ if(arr[i]&gt;arr[i+1]){ swap(&amp;arr[i], &amp;arr[i+1]);//swaps by sending the addresses of the two array elements the pointers in the swap function n++; } } }while(n&gt;0); // if counter = 0 then end (therefore the numbers are arranged correctly since no swapping happened) cout &lt;&lt; "The numbers ordered are:\n\n"; // Loop to output the arranged array for (int i =0; i&lt;10; i++){ cout &lt;&lt; arr[i] &lt;&lt; ", "; } cout&lt;&lt;endl; system("PAUSE"); return 0;} </code></pre> <p>This is the swap function:</p> <pre><code>void swap ( int *p, int *t){ int temp; temp = *p; *p = *t; *t = temp;} </code></pre> <p>I hope you guys can help me with my problem here and tell me what's wrong with this code</p> <p>Thank you all</p>

    1. CO1) Don't use `system("pause");`. 2) Prefer `std::swap` to making your own. 3) Prefer `std::sort`, but I assume the whole point of this is that you can't do that.

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.
