C++ Columns Aligment problem

Senna · 09-11-2014 10:28PM #1

Really cant get this to work, it's just 3 columns displayed by a for loop, first ones the number, second is that number squared and third is that number cubed.
Cant get the third column to line up, I've tried
<< left ,
<<right,
with setfill() and without

it coming out like this;

Maybe I've these in the wrong place?

for (int i = 0; i<=50; i+=5)
	{
		cout<< setw(10)<<"\n Integer =  "<<i;
		cout<< setw(10)<<i<< char(253) << "  = "  <<i*i;
		cout<< right <<setfill(' ') <<setw(10)<< i<< char(252) << "  = " <<i*i*i;

Thanks in advance

Can you use the \t (tab) to evenly space the characters? So from the square numbers onwards to the cubed number, drop in a \t in quotes to see if it makes any difference.

Thanks for the suggestion, but no luck. It just prints out the same. I also can't work out why the middle row is lined up correctly when I have nothing to tell it I want it aligned.
I'm sure the answer is either <<right or <<setfill(' '), but can't work it out.

Might be a bit of hassle, but you could think of putting the data in a table?

You need another setw() for the i*i part - setw() only affects the width of the next element in the stream.

Thanks for your help, but no difference. I think I'm just too dumb to get this, which has been bugging the **** out of me all week, this is due tomorrow and this is the simple part, the rest of the project was a PITA.
I could sleep easy if I could just get that last column in some sort of aliment.

Had a look at this. Looks like setw() only sets the width of the next stream element. So you need to set it multiple times, one for each number of variable length. I did the following:

#include <iostream>
#include <iomanip> 

using namespace std;

int main()
{
	int numberLength = 6;
	for (int i = 0; i<=50; i+=5)
	{
		cout<<"\n Integer = "<< left<< setw(numberLength) << i;
		cout<< right<< setw(numberLength)<< i<< char(253) << " = " << left << setw(numberLength) <<i*i;
		cout<< right<< setw(numberLength)<< i<< char(252) << " = " << left<< setw(numberLength) <<i*i*i;	
	}

	cout<< endl;

	return 0;
}

and got:

 Integer = 0          0? = 0          0? = 0     
 Integer = 5          5? = 25         5? = 125   
 Integer = 10        10? = 100       10? = 1000  
 Integer = 15        15? = 225       15? = 3375  
 Integer = 20        20? = 400       20? = 8000  
 Integer = 25        25? = 625       25? = 15625 
 Integer = 30        30? = 900       30? = 27000 
 Integer = 35        35? = 1225      35? = 42875 
 Integer = 40        40? = 1600      40? = 64000 
 Integer = 45        45? = 2025      45? = 91125 
 Integer = 50        50? = 2500      50? = 125000

(my PC doesn't print the exponent numbers).
