    Cool printing values loop.

    I am printing out values in a for loop

    for(i = 0; i<value[0]; i++)
    {
    fprintf(output,"%f\n",value[0]);
    fclose(output);

    }
    this prints data only in one column.

    but i want to print out only 10 at a time and then "\n",
    and print 10 more and so on. How would I go about doing this?

    Thankx.

    Look here.. Subsitute fprintf for the print a ___ lines.

    On a side note, why are you printing the same character over and over again? I'll assume you want to do:

    for( x = 0; x < whatever_the_decimal_value_of_this_array_cell_is; x++ )

    Smile use if statements

    Hi

    You can use the if statement and a counter inside your for loop.

    For example,

    if (i==10*counter)
    {
    printf("\n");
    }

    Code:
    for(i = 0; i<value[0]; i++)
    {
    fprintf(output,"%f ",value[0]);
    fclose(output);
    if((i % 10) == 0)
              fprintf(output, "\n");
    }

    To quzah,

    The value that is being printed to the file changes as the program is running. I want to capture all of those values in a formatted way.

    Sorry it took so long to get back to you.

    Lightbulb Set a Flag

    for(i = 0; i<value[0]; i++)
    {
    int flag = 1;
    fprintf(output,"%f",value[0]);
    ++flag;
    fclose(output);

    if (flag==10)
    {
    fprintf(output, "\n", value[0]);
    flag =1;
    }
    }



    hope this helps...

    But if you look in the actual loop, no, it actually doesn't change. Your loop, unless you happen to be making it a lot more compilicated then you actually have it, (ie: unless inside the loop you begin changing the value that is written) it will write the same character.

    Your value may change some place in your program sure, but in that loop, all that gets written is the exact same character over and over.

    quzah,

    your right. I tried the nested for loop statement and It just prints the number over and over. I guess back to the drawing board.


    thanks..
