    Formatting with Printf

    I am using the for loop below to print records from a database table to the users screen. I am having problems displaying the results in a lined up view. The data types are also below with a screen shot of how messy it currently looks. Any help is greatly appreciated getting this in a better formatted view.

    Code:
    /* PRINT TO SCREEN */
    /*READ ALL RECORDS FOUND IN TABLE - TOTAL IS STORED IN variable COUNT*/
     for( x = 0; x < row_count; x++ )
      {
    printf("COST CENTER:  LOCATION:   DESCRIPTION:        GROUP NUMBER:\n");
    printf("%-14d         %-11s       %-20s               %s\n",  cc_lkup2[x].cc,  cc_lkup2[x].cc_sn,  cc_lkup2[x].cc_desc,  cc_lkup2[x].cc_grp);
      }
    
    return (0);
    }
    Code:
    Column Name            Type       Length Nulls Defaults
    cc                               integer         2    no      no     
    cc_sn                         varchar        10   no     yes     
    cc_desc                      varchar        40   no     yes     
    cc_grp                        varchar        40   no     yes
    Screenshot of current output:

    COST CENTER: LOCATION: DESCRIPTION: GROUP NUMBER:
    249 BLDG 30 30 WASTE TREATMENT BUILDING
    COST CENTER: LOCATION: DESCRIPTION: GROUP NUMBER:
    518 127 MILL 127 TEMPER MILL ROLLING

    That's not a screen shot and dumping "output" into an unformatted (no code tags) portion of your post doesn't really help us to truly see that the output is indeed messy.

    I notice that cc_desc is varchar 40, but you allow 20 spaces for it.

    Output Question

    I will change that to 40. Thanks for pointing that out. To rephrase my question a little. I want to print the first column with a width of 10 (due to heading), second column start one space after first and contain width of 10, third column start one space after second and have a width of 40, fourth column start one space after third and have width of 40. I hope that makes sense. Thanks.

    Oh, and:
    Code:
    printf("%-14d         %-11s       %-20s               %s\n",  cc_lkup2[x].cc,  cc_lkup2[x].cc_sn,  cc_lkup2[x].cc_desc,  cc_lkup2[x].cc_grp);
    should probably be:
    Code:
    printf("%-13d %-10s %-19s %s\n",  cc_lkup2[x].cc,  cc_lkup2[x].cc_sn,  cc_lkup2[x].cc_desc,  cc_lkup2[x].cc_grp);
    Your spaces in the printf is being printed above and beyond the spaces needed to do the formatting.

    Thanks for your input matsp - Code is updated and working great now

    Code:
    /* PRINT TO SCREEN */
    /*READ ALL RECORDS FOUND IN TABLE - TOTAL IS STORED IN variable COUNT*/
     for( x = 0; x < row_count; x++ )
      {
    printf("COST CENTER: LOCATION:  DESCRIPTION:                             GROUP NUMBER:\n");
    printf("%-12d %-10s %-40s %s\n",  cc_lkup2[x].cc,  cc_lkup2[x].cc_sn,  cc_lkup2[x].cc_desc,  cc_lkup2[x].cc_grp);
      }
    
    return (0);
    }
