write a program that displays numbers in an LC-display-like style on the computer.
The input file contains several lines, one for each number to be displayed. Each line contains two integers s, n (  1<=s<=10, 0<=n<=999999 ), where n is the number to be displayed and s is the size in which it shall be displayed.
The input file will be terminated by a line containing two zeros. This line should not be processed.
Output the numbers given in the input file in an LC-display-style using s ``-'' signs for the horizontal segments and s ``|'' signs for the vertical ones. Each digit occupies exactly s+2 columns and 2s+3 rows. (Be sure to fill all the white space occupied by the digits with blanks, also for the last digit.) There has to be exactly one column of blanks between two digits.
Output a blank line after each number. (You will find a sample of each digit in the sample output.)

Sample Input  
2 12345
3 67890
0 0
Sample Output  
      --   --        --
   |    |    | |  | |  
   |    |    | |  | |  
      --   --   --   --
   | |       |    |    |
   | |       |    |    |
      --   --        --

 ---   ---   ---   ---   ---
|         | |   | |   | |   |
|         | |   | |   | |   |
|         | |   | |   | |   |
 ---         ---   ---

oops, that was a mispost. but nevertheless, as I said it would be more helpful if you state what your problem is. Without stating what the problem is, it sounds more like a homework question.

regarding the problem, a easy way out is to initialize a 2D array, with each element representing the real display. if the element contains 0, draw a space, contains 1 draw a '-', contains 2 draw a '|'. that is the simple way out though not the only way out.

CoolBreeze's 2D array is the way to go.

Basically have a static array of how many digits you need.  

Then have a function for each number:




and mark everything in the array.

Then you just need to output the array.

Hi guys,
this doesn't look like HW to me .. more it looks like ACM programming contest :)

anyway .. the algorithm you can use 2dim array simulating the dot matrix display (as ged pointed) or you can use some more sophisticated algorithm.

// you get this line, don't you? it's just your digital representation of number 0 (followed by number 1 etc.)
char *n0[9] = {" --- ", "|   |", "|   |", "|   |", "     ", "|   |", "|   |", "|   |", " --- "} ;
char *n1[9] .....

// this is just array of all numbers
char *n[][] = {n0, n1, n2, n3, n4 ...... n9} ;

// now display every line of segment display:
for (i=0; i<9; i++)
    // and in every line treat all numbers
    for (j=0; j<strlen(numberstring); j++)
        // and here just display correct line of correct number
        printf ("%s", n[numberstring[j]][i]) ;
    printf ("\n") ;


i just read your post correctly and found out the size parameter .. ok, there are 2 solutions. or you predefine the strings for all sizes, or you use some algorithm for the string creation in runtime. Following algorithm can be used

// top segment, top side segments, middle segment, bottom side segments, bottom segment
char *n0[] = {" - ", "| |", "   ", "| |", " - "} ;

1st line:
print 1st char of top (" ")
#s print 2nd char
print 3rd char

topside lines:
print 1st char of topside
#s print 2nd char
print 3rd char

etc, etc

Cheers! S.
