Alignment of Output

Im outputting text to a file, using setw and setfill.

Im trying to create this in a text file:

Code:

---

Gross Amount............. $1000.00
Federal Tax.............. $ 150.00

---

However, I cannot get it to align correctly, and often the hundreds place lines up with the thousands place in the money column. Here's the code I'm using:

Code:

---

outFile << "Gross Amount" << setfill('.') << right << setw(15) << right << " $" << grossAmount << right << endl;
outFile << "Federal Tax" <<  setfill('.')  << right << setw(15) << right << " $" << federalTax << right << endl;

---

You probably noticed theres like 4 different 'right' in each line - basically because im tossing them everywhere to try and get it to align the money to the right. Any ideas? Im new at this.

you need to put a little math in your setw's

Code:

---

#include <iostream>
#include <iomanip>
#include <string>

int main()
{
        float grossAmount=1000.00f;
        float federalTax=150.00f;
        std::string GA="Gross Amount";
        std::string FT="Federal Tax";
       
        std::cout<<std::setprecision(2)<<std::fixed<<std::right
                <<GA<<std::setfill('.')<<std::setw(30-GA.length())
                <<std::right<<" $"<<std::setfill(' ')<<std::setw(7)
                <<grossAmount<<'\n'
                <<FT<<std::setfill('.')<<std::setw(30-FT.length())
                <<std::right<<" $"<<std::setfill(' ')<<std::setw(7)
                <<federalTax<<std::endl;
       
        return 0;
}

make sure you actually understand what I did there... if not let me know I'll show you what I did

So really it has nothing to do with iostream. You should align it yourself.

it has to do with iomanip... and you aren't aligning it yourself, you're using the context of the words around it to set the amount of spaces... aligning it yourself dynamically would take much more code...

Can you please show me how? Thanks.

You'd need something like this:

Code:

---

length = number_to_string()
print number_to_string
print length-maxlength spaces
etc

---

oi... I'll take a crack at it... yuck...

What about something like this:

Code:

---

outFile << left<< setfill('.')<< setw(15)<<"Gross Amount" << right << " $" << grossAmount << endl;
outFile << left<< setfill('.')<< setw(15)<<"Federal Tax" << right << " $" << federalTax << endl;

---

please don't try to learn anything from this code...

Code:

---

#include <iostream>
#include <sstream>
#include <string>

namespace My
{
        std::string setw(const int num, const double dub);
        std::string retval;
}

int main()
{
        std::cout<<"Gross Amount............ $"<<My::setw(7,1000.00)<<'\n'
                <<"Federal Tax............. $"<<My::setw(7,150.10)<<std::endl;

        return 0;
}

std::string My::setw(const int num, const double dub)
{
        My::retval="";

        std::stringstream ss;
        ss<<dub;
        if(dub-static_cast<int>(dub)<0.01)
        {
                ss<<".00";
        }
        else if(dub-static_cast<int>(dub)<0.10)
        {
                ss<<"0";
        }
        My::retval=ss.str();

        for(int i=0; i<static_cast<int>(num-My::retval.length()); i++)
        {
                My::retval.insert(0," ");
        }

        return My::retval;
}

Especially not how to code a code formatter . . . :)

yeah, yeah. you build me a better one.

edit: there, happy?

It takes me some time to understand what you have written.

Thank you, I got it. I recently had a little problem with aligning that I solved it with your help.

Yes, because now I get to post the link for my (old) code formatter: http://dwks.theprogrammingsite.com/myprogs/codeform.htm

:D

well then... thank you :)

I may end up using yours... mine has an HTML output part too, but it doesn't work >.<
