Before I start, I would like to stay thanks to the people who helped before in my previous threads. Sorry if I can't reply quickly at that time due to connection issues.

Back to the problem. I am working on a stemplot(http://en.wikipedia.org/wiki/Stem_and_leaf_plot), which prints the data(the plot thing) into the text file. The data is pre-sorted, and the numbers were obtained using RNG, but what I'm having trouble is how to place each of them into their respective intervals.

Here's the code:

//////////////////////////////////////////////
fp=fopen("plot.txt","r");
putchar('\n');
    for(x=0;x<20;x++){
        fscanf(fp,"%d",&storage[x]);
    }    
fclose(fp);
//Arranged data will be placed into their respective rows in descending order.
for(x=0;x<20;x++){
}

//Prints the data into a text file.
fp=fopen("plot.txt","w");        
printf("Stem-and-leaf plot:\n\n");
fprintf(fp,"Stem-and-leaf plot:\n\n");
    for(x=0;x<10;x++){
    printf("%2d| ",9-x);
    fprintf(fp,"%2d| ",(9-x));        
        
        for(y=0;y<10;y++){
            if(storage[x]){
            }
        
        plot[x][y]=storage[x];
        printf("%2d ",plot[x][y]);
        fprintf(fp,"%2d ",plot[x][y]);
        }
    
    putchar('\n');
    fputc('\n',fp);    
    }
fclose(fp);
    
}

I've already placed an "if" statement inside the plot's loop. But when I did it, it only prints the first ten data in the list. Any advice???

This is the output, without the if statement in.:

Stem-and-leaf plot:

 9| 97 97 97 97 97 97 97 97 97 97 
 8| 96 96 96 96 96 96 96 96 96 96 
 7| 86 86 86 86 86 86 86 86 86 86 
 6| 82 82 82 82 82 82 82 82 82 82 
 5| 76 76 76 76 76 76 76 76 76 76 
 4| 68 68 68 68 68 68 68 68 68 68 
 3| 54 54 54 54 54 54 54 54 54 54 
 2| 53 53 53 53 53 53 53 53 53 53 
 1| 52 52 52 52 52 52 52 52 52 52 
 0| 49 49 49 49 49 49 49 49 49 49

I believe you're making it hard for yourself. Just:

1) Sort the data points for each row in the 2D array.
2) Print the stem, the | and the columns of data from that stems row of the array.

And you're done. Don't use Rube Goldberg logic - simplicity leads to clarity, leads to a quick and bug free program. (If there can be such a thing! ;) )

That explains it. =/

Would it work even with the RNG as the basis?
