    <p>I have a file with random characters in basically a word search format. i would like to be able to take all the characters in it and put it into a 2d puzzle array so that i am able to type something like printf("the value is %c",puzzle[2][2]); and it will print the value in the 3rd row and 3rd column (since it starts at 0...) heres my code so far.</p> <pre><code>#define MAXROWS 60 #define MAXCOLS 60 #include &lt;stdio.h&gt; #include &lt;string.h&gt; #include &lt;stdlib.h&gt; #include &lt;math.h&gt; main() { char TableFileName[100]; char PuzzleFileName[100]; char puzzle[MAXROWS][MAXCOLS]; char line[MAXCOLS]; FILE *TableFilePtr; int cols = 0; int rows = 0; printf("Please enter the table file name: "); scanf("%s",TableFileName); /* ... */ TableFilePtr = fopen(TableFileName, "r"); while (fgets(line, sizeof line, TableFilePtr) != NULL &amp;&amp; rows &lt; MAXROWS) { for (cols; cols&lt;(strlen(line)-1) &amp;&amp; cols &lt; MAXCOLS; ++cols) { puzzle[rows][cols] = line[cols]; } ++rows; } printf("%c",puzzle[2][2]); } </code></pre> <p>the puzzle[x][y] doesnt contain any values once the program runs. any ideas?</p> <p>update1: changed for cols to for cols=0 update2: added printf("\nthe rows are at %d, cols at %d, puzzle[%d,%d]=%c line[cols]=%c",rows,cols,rows,cols,puzzle[rows,cols],line[cols]); to for loop update3: after update 2, i see the line[cols] characters are getting every character in the puzzle, but not int the correct order. also, the line[cols] isnt correctly being put into the puzzle[rows][cols]. heres some of what what im seeing (not sure why its making me put it as code but whatever):</p> <pre><code>the rows are at 0, cols at 0, puzzle[0,0]=l line[cols]=A the rows are at 0, cols at 1, puzzle[0,1]=▒ line[cols]= the rows are at 0, cols at 2, puzzle[0,2]=▒ line[cols]=B the rows are at 0, cols at 3, puzzle[0,3]= line[cols]= the rows are at 0, cols at 4, puzzle[0,4]=\ line[cols]=D the rows are at 0, cols at 5, puzzle[0,5]=▒ line[cols]= the rows are at 0, cols at 6, puzzle[0,6]=▒ line[cols]=E the rows are at 0, cols at 7, puzzle[0,7]= line[cols]= the rows are at 0, cols at 8, puzzle[0,8]=L line[cols]=Q the rows are at 0, cols at 9, puzzle[0,9]=▒ line[cols]= the rows are at 0, cols at 10, puzzle[0,10]=▒ line[cols]=T </code></pre> <p>the A,B,D,E,A,T are correct but... A should be puzzle[0,0], B should be [0,1] D should be [0,2] etc...</p> <p>heres a sampler of the input... (would be in a txt file)</p> <pre><code>K N R D J P L H X E K B W M X A M U Y A L E F Q N D L D B D B S W W M T F B K Z D G A L V L K U N U R C R I E I H N L A N D N T O V P O G R U U Y X E D L Y R M Q D T T Y C G Y E M A S I E X P V Z N W H X B D G G R T K V C W M Y C X A M I E U T Z J U O C N F F L R E F B T D R Y W R K V A C B H G L C F D Y X R Z Q E R E H N Q D S J H T R G E N Y Y K F J V G S C G D H O G K A F E M I S S Q P S J Z A B V A A P E E P R K F T A H W C G B J N N L W B F V F Z Y T V Y E O C Y A D L Q Q P P F V W K M E U V O </code></pre>

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.
