Cplusplus problem with formatting?

[oliviajayden]

I'm trying to make it so my program lines up 3 things orderly such as

5-------Cakes for $-----59.00
2----Balloons for $-----62.00
(without the -)
I have this

cout << left << setw(6) << cakes
<< right << setw(4) << "Birthday Cakes for $"
<< right << setw(8) << fixed << setprecision(2) << cake_price << endl;
cout << left << setw(6) << balloons
<< right << setw(4) << "Birthday Balloons for $"
<< right << setw(8) << fixed << setprecision(2) << balloon_price << endl;
How can I fix it to be like the one above?

Does this version illustrate your problem:

#include <iostream>
#include <iomanip>

int main()
{
  using namespace std;
  int cakes {5};
  int balloons {22};
  double cakep {59.0};
  double ballp {3.14};

  cout.fill('=');
  cout << left << setw(6) << cakes;
  cout.fill('_');
  cout << right << setw(24) << "Birthday Cakes for $";
  cout.fill('#');
  cout << right << setw(8) << fixed << setprecision(2) << cakep << '\n';
  cout.fill(' ');

  cout << left << setw(6) << balloons
    << right << setw(24) << "Birthday Balloons for $"
    << right << setw(8) << fixed << setprecision(2) << ballp << '\n';
}

5=====____Birthday Cakes for $###59.00
22     Birthday Balloons for $    3.14

#include <iostream>
#include <iomanip>
#include <cmath>
using namespace std;


void print( int number, string title, double cost )
{
   const int Wnum = 3, Wtitle = 20, Wcost = 6;

   if ( number + 0.5 > pow( 10, Wnum ) || title.size() > Wtitle || cost + 0.5 > pow( 10, Wcost - 3 ) )
   {
      cout << "Unable to format\n";
      return;
   }

   cout << setw( Wnum   ) << left  << number << " "
        << setw( Wtitle ) << left  << title  << " for $"
        << setw( Wcost  ) << right << setprecision( 2 ) << fixed << cost << '\n';
}


int main()
{
   print( 5, "Birthday cakes"   , 59.0 );
   print( 2, "Birthday balloons", 62.0 );
}

5   Birthday cakes       for $ 59.00
2   Birthday balloons    for $ 62.00

#include <iomanip>
#include <iostream>

struct Item {
	int	number;
	std::string description;
	double price;
};

int main() {
	Item items[] = {
		{ 5, "Cakes", 59.0 },
		{ 2, "Ballons", 62.0 }
	};

	std::cout << std::setfill('-');	// show - between fields for debug

	for (const Item& item : items)
		std::cout
			<< std::setw(2) << item.number
			<< std::setw(11) << item.description << " for $"
			<< std::setw(5) << std::setprecision(2) << std::fixed << item.price
			<< std::endl;
