    Thumbs up Lining up decimals & text - code included inside.

    Hello, I am having troubles lining up decimals and text in my output.

    This is what my output consists of

    Code:
    No. Last Name     Gross     LTB     EI     CPP     FED TAX     TOT DED     NET PAY
    111 Lastname01       288.40         4.00         4.04         4.61        67.83        80.48       207.92
    222 Lastname02      4807.69        96.00        11.80        11.20      1942.10      2061.10      2746.60
    333 Lastname03       405.51         8.00         5.68         6.49        97.53       117.69       287.82
    444 Name     11057.69       100.00        11.80        11.20      4606.47      4729.47      6328.22
    555 Name       339.68         6.00         4.76         5.43        79.89        96.08       243.60
    666 Name       353.32         6.00         4.95         5.65        83.10        99.70       253.62
    777 Name       439.20         8.00         6.15         7.03       108.92       130.09       309.11
    888 Name       321.20         6.00         4.50         5.14        75.55        91.18       230.02
    999 Name       321.92         6.00         4.51         5.15        75.72        91.37       230.55
    As you can see its fairly messy.

    Here is the code I have written.

    Code:
    fprintf(outputfile, "No. Last Name     Gross     LTB     EI     CPP     FED TAX     TOT DED     NET PAY");
    and

    Code:
    fprintf(outputfile, "\n%d %s %12.2lf %12.2lf %12.2lf %12.2lf %12.2lf %12.2lf %12.2lf", empnum, lname, grosspay, ltb, 
    																 employment_ins, can_pen_plan, fed_tax,
    																 ltb + employment_ins + can_pen_plan + fed_tax,
    																 grosspay - (ltb + employment_ins + can_pen_plan + fed_tax));

    I would appreciate any help towards fixing up and formatting this text. Thanks in advance.

    As well, its my first post on the forums here

    PS: I hope this is all the required code needed, if more is needed - let me know.

    Add a width specifier for your string specifier.

    Really? It works for me.
    Code:
    #include <stdio.h>
    struct foo
    {
            char *word;
            float ta;
            float me;
            float hom3z;
            float yo;
    } peace[] =
    {
            { "out", 1.337, 1.2, 2.333, 4.444 },
            { "w0rd", 2.5, 6666.9, 867.5309, 0.1812 },
            { "give", 0.0, 2.222, 12.9, 999.0 },
            { "propz", 1.1, 3.333, 23141.2, 12.0 },
            { "yo", 0.0, 0.0, 10.01, 9.9 }
    };
    
    int main( void )
    {
            int x;
            for( x = 0; x < sizeof peace / sizeof peace[0]; x++ )
            {
                    printf("%-20s %-15.5f %-15.5f %-15.5f %-15.5f\n",
                                    peace[x].word,  peace[x].ta, peace[x].me,
                                    peace[x].hom3z, peace[x].yo );
            }
            return 0;
    }
    Murtaugh: Word, Riggs!

    Riggs: Word Rog.

    Murtaugh: What are we talking about?

    Riggs: Word, four letters, starts with W, OR in the middle, D on the end. Word.

    Murtaugh: Oh, that word.

    I have no idea what that code does. I was only recently taught to use things like this
    Code:
    %12.2lf
    .

    The format tags follow this prototype:
    %[flags][width][.precision][modifiers]type

    You can learn about these options here.

    For a brief summary:

    The width is 12 representing a minimum number of characters to be printed. If the value to be printed is shorter than this number the result is padded with blanks.

    Your precision is .2 representing number of digits to be printed after the decimal point. [if nothing specified default is 6].

    Your modifier is l representing the argument interpreted as long int (interger types) or double (floating point types).

    Your type is f representing a decimal floating point.

    Segmentation Fault: I am an error in which a running program attempts to access memory not allocated to it and core dumps with a segmentation violation error. This is often caused by improper usage of pointers, attempts to access a non-existent or read-only physical memory address, re-use of memory if freed within the same scope, de-referencing a null pointer, or (in C) inadvertently using a non-pointer variable as a pointer.

    Ok, so I need to change the "%12.2lf" to another number?

    That doesnt fix anything.

    How about this:

    Code:
    int main( void )
    {
            int x;
            for( x = 0; x < sizeof peace / sizeof peace[0]; x++ )
            {
                    printf("%20s %15.5f %15.5f %15.5f %15.5f\n",
                                    peace[x].word,  peace[x].ta, peace[x].me,
                                    peace[x].hom3z, peace[x].yo );
            }
    
      system("PAUSE");	
      return 0;
    }
