    <p>I have a problem that I need some help in figuring out. I was hoping I could get a few pointers on a better way to approach what i'm doing. My main issue is a few lines below (//This is whats hanging me up) and described at the bottom of page.</p> <p>I need to permutate all possible outcomes of a phone number: (not just dictionary words)</p> <p>I.E. 222-2222</p> <p>Should output a list 3^7 long with all the possible permutations of a,b,c</p> <p>I.E.</p> <pre><code>AAAAAAA AAAAAAB AAAAAAC AAAAABA // THIS IS WHATS HANGING ME UP AAAAABB AAAAABC AAAAACA // HERE TOO AND SO ON </code></pre> <p>MY CODE (purposely shortened for testing) GIVES ME:</p> <pre><code>AAAA AAAB AAAC AABC AACC ABCC ACCC BCCC CCCC </code></pre> <p>I'm a beginning programming student so my knowledge goes as far as using for, while, if, statements and grabbing individual chars from the array.</p> <p>Here's what my code looks like so far: (this is a part of a function. Code missing)</p> <p>char alphaFunc(char n[]){</p> <pre><code>int d1=n[0]-48; int d2=n[1]-48; int d3=n[2]-48; int d4=n[3]-48; int d5=n[4]-48; int d6=n[5]-48; int d7=n[6]-48; int a=0,b=0,c=0,d=0,e=0,f=0,g=0; int i=0; char charArray[10][4]={ {'0','0','0'},{'1','1','1'},{'A','B','C'}, {'D','E','F'},{'G','H','I'},{'J','K','L'},{'M','N','O'}, {'P','R','S'},{'T','U','V'},{'W','X','Y'} }; while(i &lt;=14){ printf("%c%c%c%c\n", charArray[d1][a], charArray[d2][b],charArray[d3][c],charArray[d4][d], charArray[d5][e],charArray[d6][f],charArray[d7][g]); g++; if(g==3){ g=2; f++; } if(f==3){ f=2; e++; } if(e==3){ e=2; d++; } </code></pre> <p>I'm not exactly looking for someone to do this for me I just need a little help in figuring out which sort of statement will work b/c when you have a digit get to CharArray[d-][a] location [3] and reset it to [0] it sends you to a different part of the loop. (hope that makes sense).</p>

    2. COThe links I provided show how to generate combinations of items from a list (you asked for "pointers to a better way", and I posted links to two). You can find the issue you're having with your code by using the debugger to step through it. Set a breakpoint on the line you have a question about, run with debugging until you stop at the breakpoint, and single-step through the code watching the variables to see what's happening with them. (t would help you if you used more readable variable names, too.)

    3. COThank you for your help. I was more looking for a quick hint on what type of loop I need to use IE (for, while, if..) and since this is a online class that is one step above beginning programming I don't know how to use a debugger b/c we log in to a linux server.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
